QUESTION 2
Refer to the Exhibit.
You use the Start button in the administration console to start managed2 successfully. Which two statements must be true?
A. Managad2 is part of a cluster.
B. The Administration Server is running.
C. Managed2 has applications deployed to it.
D. The Node Manager for machine2 is configured and running.
E. The Node Manager for the Administration Server machine is configured and running.
Correct Answer: BD
Section: (none)
Explanation
B: The administration server must be running.
Note: A WebLogic Server administration domain is a logically related group of WebLogic Server resources. Domains include a special WebLogic Server instance
called the Administration Server, which is the central point from which you configure and manage all resources in the domain.
D:
Node Manager is a WebLogic Server utility that enables you to start, shut down, and restart Administration Server and Managed Server instances from a remote
location. Although Node Manager is optional, it is recommended if your WebLogic Server environment hosts applications with high availability requirements.
A Node Manager process is not associated with a specific WebLogic domain but with a machine. You can use the same Node Manager process to control server
instances in any WebLogic Server domain, as long as the server instances reside on the same machine as the Node Manager process. Node Manager must run on
each computer that hosts WebLogic Server instances -- whether Administration Server or Managed Server -- that you want to control with Node Manager.
Incorrect answers:
A: We could not know if Managed2 is in a cluster or not.
C: We could not know if Managed2 has deployed applications.
QUESTION 3
Within your data center, the Administration and Managed Servers utilize a shared, central storage device, which server's access via NFS.
In this scenario, your application files no longer need to be copied to servers across the network. Which server attribute allows you to override this behavior?
A. Startup Mode
B. Staging Mode
C. Root Directory
D. Listen Address
Correct Answer: B
Section: (none)
Explanation
The server staging mode specifies the default deployment mode for a server if none is specified at deployment time. For example, the server staging mode is used
if you deploy an application or module using weblogic.Deployer and you do not specify a staging mode.

http://docs.oracle.com/cd/E12840_01/wls/docs103/ConsoleHelp/taskhelp/deployment/SetAServe rStagingMode.html
QUESTION 4
An EJB application is targeted to a cluster. Remote EJB clients can therefore take advantage of WebLogic Server's load balancing and failover capabilities.
However, a proxy server exists between the clients and the cluster, which performs IP address translation. Which cluster attribute should you modify to ensure that
load balancing and failover work correctly?
A. Multicast Address
B. Persistent Store

C. Cluster Address
D. Migration Basis
E. Replication Channel
Correct Answer: C
Section: (none)
Explanation
Note:
Updating Proxy Service Configurations for an Expanded Cluster

QUESTION 5
You run the default startmanageWeblogic (.cmd in Windows) script as shown here:
startmanageWeblogic.sh server1 http://192.168.1.102:8001.
What does this do?
A. It starts the administration server named server1, which is running at 192.168.1.102.8001.
B. It starts the managed server named server1, which is running at 192.168.1.102.8001.
C. It starts the managed server named server1 whose Node Manager is running at 192.168.1.102.8001.
D. It starts the Managed Server named server1 whose Administration Server is running at 192.168.1.102:8001.
Correct Answer: D
Section: (none)
Explanation
A Managed Server is a WebLogic Server instance that runs deployed applications. It refers to the Administration Server for all of its configuration and deployment
information. Usually, you use Managed Servers to run applications in a production environment.
See step 4 and 5 below in particular:
To use the WebLogic Server scripts to start Managed Servers:
1. Refer to Starting Servers: Before You Begin for prerequisite tasks.
2. If you have not already done so, create one or more Managed Servers.
See Creating WebLogic Domains Using the Configuration Wizard or "Create Managed Servers" in the Administration Console Online Help.
3. Start the domain's Administration Server.
4. In a shell (command prompt) on the computer that hosts the Managed Server, change to the directory that contains the startManagedWebLogicscript:
DOMAIN_NAMEbinstartManagedWebLogic.cmd (Windows)
DOMAIN_NAME/bin/startManagedWebLogic.sh (UNIX)
where DOMAIN_NAME is the directory in which you located the domain. By default, this directory is BEA_HOMEuser_projectsdomainsDOMAIN_NAME.
5. Enter one of the following commands:
startManagedWebLogic.cmd managed_server_name
admin_url (Windows)
startManagedWebLogic.sh managed_server_name
admin_url (UNIX)
where managed_server_name specifies the name of the Managed Server and admin_url specifies the listen address (host name or IP address) and port number of
the domain's Administration Server.
For example, the following command uses startManagedWebLogic.cmd to start a Managed Server named myManagedServer. The listen address for the domain's
Administration Server is AdminHost:7001:
c:beauser_projectsdomainsmydomainbinstartManagedWe
bLogic.cmd myManagedServer http://AdminHost:7001
6. For each Managed Server that you want to start, open a separate command shell and follow steps 4 and 5. If you are starting Managed Servers on another
machine, log in to that machine (remotely or locally) and then follow steps 4 and 5.

A. Create a separate application archive to use with each domain.
B. Create a separate deployment plan file to use with each domain.
C. Create and register a custom deployment listener.
D. Modify the application code to determine the current domain.
Correct Answer: B
Section: (none)
Explanation
A WebLogic Server deployment plan is an optional XML document that you use to configure an application for deployment to a specific WebLogic Server
environment, such as a domain.

A. When you create a cluster, you must add at least one server to it.
B. Only managed servers can be in a cluster.
C. The administration server is automatically added to a new cluster.
D. You must explicitly identify which servers belong to the cluster.
Correct Answer: AB
Section: (none)
Explanation
A cluster must include at least one server.
A clustered is administered through an administration server, but the cluster consists of managed servers only.
QUESTION 12
Consider a single JMS module that includes a connection factory as well as queue. Based on your system's requirements, the connection factory needs to be made
available to all servers in the domain. The queue, on the other hand, can be targeted to only a single JMS server domain.
What is the best way to achieve the desired JMS setup?
A. Create two subdeployments within the JMS module.
B. Target the JMS server to the JMS module.
C. Target the JMS module to the entire domain.
D. Replace the queue with a topic.
Correct Answer: A
Section: (none)
Explanation
A subdeployment is a mechanism by which JMS module resources (such as queues, topics, and connection factories) are grouped and targeted to a server
resource (such as JMS servers, server instances, SAF agents, or a cluster).
For example, you can group a connection factory with stand-alone queues or topics in a subdeployment targeted to a specific JMS server, which guarantees that all
these resources are co-located to avoid extra network traffic. Another advantage of such a configuration would be if the targeted JMS server needs to be migrated
to another WebLogic server instance, then the connection factory and all its connections will also migrate along with the JMS server's destinations. However, when
stand-alone queues or topics are members of a subdeployment, a connection factory can only be targeted to the same JMS server.

QUESTION 13
Which three attributes are part of the configuration of an existing Managed Server and can be modified through the" administration console?
A. name of the server
B. the cluster it is in
C. the machine it runs on

D. its replication group
E. whether it is in Development Mode or Production Mode
F. that it should become the Administration Server for the domain
Correct Answer: BCD
Section: (none)
Explanation
B: Attribute label: Cluster
The cluster to which this server belongs. If set, the server will listen for cluster multicast events.
This is a configurable attribute.
C: Attribute label: Machine
The WebLogic Server host computer (machine) on which this server is meant to run.
This is a configurable attribute.
D: Server --> Configuration --> Cluster
A WebLogic Server cluster is a group of servers that work together to provide a more scalable, more reliable application platform than a single server.
Use this page to specify a server's primary and secondary replication group, cluster weight, and the interface address used to handle multicast traffic.
Attribute label: Replication Group
Description: Defines preferred clustered instances considered for hosting replicas of the primary HTTP session states created on the server.
Incorrect answers:
A: Attribute Label: Name
After you have created a server, you cannot change its name. Instead, clone the server and provide a new name for the clone.
Note:
An alphanumeric name for this server instance. This field will not accept spaces. Each server instance in your WebLogic environment must have a unique name,
regardless of the domain or cluster in which it resides, or whether it is an Administration Server or a Managed Server. Within a domain, each server, machine,
cluster, JDBC connection pool, virtual host, and any other resource type must be named uniquely and must not use the same name as the domain.
F: There is no attribute within a server's configuration that designates it as an Administration Server or Managed Server. Instead, the first server instance that you
start in a domain always functions as the Administration Server.
Reference: BEA WebLogic Server 8.1 Documentation, Server --> Configuration --> General
QUESTION 14
Which can be associated with multiple domains?
A. Cluster
B. Server Log
C. Node Manager
D. Administration Server
Correct Answer: C
Section: (none)
Explanation
A Node Manager process is not associated with a specific WebLogic domain but with a machine. You can use the same Node Manager process to control server
instances in any WebLogic Server domain, as long as the server instances reside on the same machine as the Node Manager process.
Incorrect answers:
A: A cluster is part of a particular WebLogic Server domain.
D: In each domain, one WebLogic Server instance acts as the Administration Server--the server instance which configures, manages, and monitors all other server
instances and resources in the domain. Each Administration Server manages one domain only. If a domain contains multiple clusters, each cluster in the domain
has the same Administration Server.

Explanation
A: Main Steps for Creating Packaged JMS Application Modules
Follow these steps to configure a packaged JMS module:
If necessary, create a JMS server to target the JMS module to, as explained in "Configure JMS Servers" in the Administration Console Online Help.
Create a JMS system module and configure the necessary resources, such as queues or topics, as described in "Configure JMS system modules and add JMS
resources" in the Administration Console Online Help.
The system module is saved in configjms subdirectory of the domain directory, with a "- jms.xml" suffix.
Copy the system module to a new location, and then:
Give the module a unique name within the domain namespace.
Delete the JNDI-Name attribute to make the module application-scoped to only the application. Add references to the JMS resources in the module to all applicable
J2EE application component's descriptor files, as described in Referencing a Packaged JMS Application Module In Deployment Descriptor Files.
Package all application modules in an EAR, as described in Packaging an Enterprise Application With a JMS Application Module.
Deploy the EAR, as described in Deploying a Packaged JMS Application Module.
D: JMS application modules can be packaged as part of an Enterprise Application Archive (EAR), as a packaged module. Packaged modules are bundled with an
EAR or exploded EAR directory, and are referenced in the weblogic-application.xml descriptor. The packaged JMS module is deployed along with the Enterprise
Application, and the resources defined in this module can optionally be made available only to the enclosing application (i.e., as an application-scoped resource).
Such modules are particularly useful when packaged with EJBs (especially MDBs) or Web Applications that use JMS resources. Using packaged modules ensures
that an application always has required resources and simplifies the process of moving the application into new environments.

QUESTION 17
Which two statements are true about a WebLogic domain?
A. It is the basic administrative unit of WebLogic Server.
B. It is an optional administrative construct to organize groups of WebLogic
C. Administration Servers are defined within a domain, but Managed Servers
D. You must first have a domain to define a WebLogic Server cluster.
E. Every domain has one Administration Server and at least one managed server
Correct Answer: AD
Section: (none)
Explanation
A: A domain is the basic administration unit for WebLogic Server instances.
D: To define a WebLogic Server cluster there must be a domain:
Note: Before you start the Managed Servers in a domain, start the Administration Server. When you start a standalone or clustered Managed Server, it contacts the
Administration Server for its configuration information. In this way, the Administration Server operates as the central control entity for the configuration of the entire
domain.

QUESTION 18
Which two statements are true about multicast communication within a cluster?
A. Multicast can be used for cluster heartbeat messages.
B. Multicast is used to replicate session state between servers.
C. Multiple clusters can share the same multicast address and port.
D. You may disable multicast on individual cluster members.
E. Multicast traffic is often limited to a single subnet.
Correct Answer: AE
Section: (none)
Explanation
A: WebLogic Server instances in a cluster communicate with one another using two basic network technologies:
* IP sockets, which are the conduits for peer-to-peer communication between clustered server instances.
* IP unicast or multicast, which server instances use to broadcast availability of services and heartbeats that indicate continued availability.
E: In many deployments, clustered server instances reside within a single subnet, ensuring multicast messages are reliably transmitted. However, you may want to
distribute a WebLogic Server cluster across multiple subnets in a Wide Area Network (WAN) to increase redundancy, or to distribute clustered server instances
over a larger geographical area.

QUESTION 19
Identify two true statements about an Oracle WebLogic Server JMS Connection Factory.
A. A default JMS Connection Factory exists and is named weblogic.jms.connections
B. A Connection Factory can be targeted to only one WebLogic Server.
C. A JMS Connection Factory's Default Priority and Default Time-to-Live attribute cannot be modified after the Connection Factory is created.
D. A JMS Connection factory can be created as a system module resource within the administration console.
Correct Answer: BD
Section: (none)
Explanation
Incorrect answers:
A: WebLogic JMS defines two default connection factories, which you can look up using the following JNDI names:
weblogic.jms.ConnectionFactory
weblogic.jms.XAConnectionFactory
C: Both Default Priority and Default Time-to-live can be changed:
Default Priority: This attribute is dynamic. It can be changed at any time. However, changing the value does not affect existing connections. It only affects new
connections made with this connection factory.
Default Time-to-Live:
This attribute is dynamic. It can be changed at any time. However, changing the value does not affect existing connections. It only affects new connections made

with this connection factory.

Which three statements are true about WebLogic users and groups?
A. A user is associated with a single security provider.
B. A user can be a member of several groups.
C. A group can contain other groups.
D. A group consists of a name and a password.
E. A group is associated with multiple security providers.
F. Both users and groups are assigned a keystore.
Correct Answer: ABC
Section: (none)
Explanation
B: For efficient security management, BEA recommends adding users to groups. A group is a collection of users who usually have something in common, such as
working in the same department in a company.
C: Example of group nesting:
Every user is a member of the everyone group.
The users group is nested within the everyone group.
Note: Security Providers - are modules that provide security service to application to protect Weblogic resource.
Types of security providers in WebLogic Server are
Authentication Provider, Authorization Provider, Auditing Providers, Credential Mapping Provider, Identity Asser- tion Provider, Principal Validation Provider,
Adjudication Providers, Role Mapping Providers, Certificate Lookup and Validation Providers, Keystore Providers and Realm Adapter providers
Incorrect answers:
D: There is no password for a group.
F: A keystore is a mechanism designed to store password-protected store private keys and trusted CA certificates. In the WebLogic Server security architecture, the
WebLogic Keystore provider is used to access keystores. You cannot use a custom Keystore provider with WebLogic Server.

QUESTION 22
Your production JMS server and/or its consumers are not able to handle the incoming message workload. The number of messages on the server never stabilizes
and the server eventually becomes overload.
Which JMS server attribute will best help prevent the JMS server from being overloaded by producers?
A. Producer Pause High
B. Messages Threshold High
C. Reconnect Polity
D. Paging Directory
E. Pool Maximum Capacity
Correct Answer: B
Section: (none)
Explanation
JMS Configuration option ' Messages Threshold High':
The upper threshold (number of messages stored in this JMS server) that triggers flow control and logging events. A value of -1 disables the events for this JMS
server. If the number of messages exceeds this threshold, the triggered events are:
Log Messages
- A message is logged on the server indicating a high threshold condition.
Flow Control
- If flow control is enabled, the JMS server becomes armed and instructs producers to begin decreasing their message flow.
Reference: Administration Console Online Help, JMS Server: Configuration: Thresholds and Quotas
QUESTION 23
Which three statements are true about WebLogic clusters?
A. Clusters provide clients with transparent failover.
B. EJB applications can be targeted to an entire cluster.
C. All cluster members must bind to the same port number.
D. Cluster members replicate application data by using heartbeats.
E. Cluster members can be associated with one or more domains.
F. Web applications require a proxy in order to be used in a cluster.

Correct Answer: ABC
Section: (none)
Explanation
A: If an object is clustered, failover and load balancing for that object is available. In a WebLogic Server cluster, application processing can continue when a server
instance fails. You "cluster" application components by deploying them on multiple server instances in the cluster--so, if a server instance on which a component is
running fails, another server instance on which that component is deployed can continue application processing.
The choice to cluster WebLogic Server instances is transparent to application developers and clients.
B: A clustered application or application component is one that is available on multiple WebLogic Server instances in a cluster. If an object is clustered, failover and
load balancing for that object is available. Deploy objects homogeneously--to every server instance in your cluster --to simplify cluster administration, maintenance,
and troubleshooting.
Web applications can consist of different types of objects, including Enterprise Java Beans (EJBs), servlets, and Java Server Pages (JSPs).
Note: Load balancing and failover for EJBs and RMI objects is handled using replica-aware stubs, which can locate instances of the object throughout the cluster.
C: Cluster Multicast Address and Port
Identify the address and port you will dedicate to multicast communications for your cluster.
Incorrect answers:
D: Cluster heartbeats-- Each WebLogic Server instance in a cluster uses multicast to broadcast regular "heartbeat" messages that advertise its availability. By
monitoring heartbeat messages, server instances in a cluster determine when a server instance has failed.
E: All server instances in a cluster must reside in the same domain; you cannot "split" a cluster over multiple domains. Similarly, you cannot share a configured
resource or subsystem between domains.
F: Proxy might be needed depending how you set up the architecture, but a proxy is not required for web applications.

QUESTION 24
Which three statements are true when an Administration Server is compared to a managed server?
A. A domain must have at least one of each type of server.
B. Administration Server keeps a domain log, but a Managed Server does not.
C. A Managed Server keeps a server log, but an Administration Server does not.
D. When a Managed Server comes up, it asks its Administration Server for the latest configuration.
E. An Administration Server manages the domain configuration.
F. JEE applications are deployed only to a Managed Server.
Correct Answer: DEF
Section: (none)
Explanation
D: When a Managed Server starts, it contacts the Administration Server to retrieve its configuration information. If a Managed Server is unable to connect to the
specified Administration Server during startup, it can retrieve its configuration directly by reading a copy of the config.xml file and other files located on the Managed
Server's own file system.
E: One instance of WebLogic Server in each domain acts as an Administration Server. The Administration Server provides a central point for managing a WebLogic
Server domain.
F: For a typical production system, BEA recommends that you deploy your applications only on Managed Servers. This practice allows you to dedicate the
Administration Server to configuration and monitoring of the domain, while one or more Managed Servers service your applications.
Incorrect answers:
A: In a domain with only a single WebLogic Server instance, that server functions both as Administration Server and Managed Server.
B, C: Many WebLogic Server operations generate logs of their activity. Each server has its own log as well as a standard HTTP access log. These log files can be
configured and used in a variety of ways to monitor the health and activity of your servers and applications.

QUESTION 30
Your server includes an application that uses a generic JDBC data source to connect to a database. However, the network connection between the server and the
database is not 100% reliable.
You wish to avoid scenarios in which the application fails due to a failed JDBC connection. Identify two data source attributes to help accomplish this.
A. Statement Cache
B. Pool Reserve Mode
C. Test Table Name
D. Test Connection Mode
E. Test Connections on Reserve
Correct Answer: AE
Section: (none)
Explanation
A: Each connection in a data source has its own individual cache of prepared and callable statements used on the connection. However, you configure statement
cache options per data source. That is, the statement cache for each connection in a data source uses the statement cache options specified for the data source,
but each connection caches it's own statements.
E: When Test Connections On Reserve is enabled, when your application requests a connection from the data source, WebLogic Server tests the connection using
the query specified in Test Table Name before giving the connection to the application.
Testing reserved connections can cause a delay in satisfying connection requests, but it makes sure that the connection is viable when the application gets the
connection.

QUESTION 31
You have selected Configuration Archive Enabled for the domain. When a configuration change and activated, where is the previous version of the configuration
archived?
A. in the Oracle database
B. in the config directory
C. in the pending directory
D. in the console-ext directory
E. in the configArchive directory
Correct Answer: E
Section: (none)
Explanation
You can configure WebLogic Server to make backup copies of the configuration files. This facilitates recovery in cases where configuration changes need to be
reversed or the unlikely case that configuration files become corrupted. When the Administration Server starts up, it saves a JAR file named config-booted.jar that
contains the configuration files. When you make changes to the configuration files, the old files are saved in the configArchive directory under the domain directory,
in a JAR file with a sequentially-numbered name like config-1.jar. Reference: Understanding Domain Configuration, Configuration File Archiving http://

QUESTION 32
When a typical application utilizes a JDBC data source, the process involves several steps.
Identify three of these steps.
A. The application returns the connection to the data source.
B. The application looks up the data source using the JNDI name.
C. The application tests the connection to verify the database's availability.
D. The application adds a new connection to the data source if none are available.
E. The application requests a connection from the data source.
Correct Answer: BDE
Section: (none)
Explanation
Applications look up the data source on the JNDI tree or in the local application context (B) and then reserve a database connection with the getConnection (E)
method. Data sources and their connection pools provide connection management processes that help keep your system running and performant.
B: JNDI Name - Enter the JNDI path to where this JDBC data source will be bound. Applications look up the data source on the JNDI tree by this name when
reserving a connection.
Note: If you've done any work with JDBC DataSources in a Web application, you already understand the basic process: create an initial JNDI (Java Naming and
Directory Interface) context, then use the context to perform a "lookup" to retrieve your DataSource.
Incorrect answers:
C: The test is optional and if it is executed by weblogic before releasing the connection to the application

QUESTION 33
As an Oracle WebLogic Server administrator, you are given an EAR file application to deploy.
Identity three reasons for creating an EAR file first.
A. After the .ear file has been deployed, the developer will not have to ask for your assistance to deploy it again.
B. The EAR file is created to avoid namespace clashes in the Java code.
C. The EAR file can contain multiple WAR, EAR, and other resources to easily bundle together.
D. The EAR file is required if you are deploying an application.
E. The EAR file can declare application-wide security roles definitions.

Correct Answer: ABE
Section: (none)
Explanation
E: An EARfile contains:
* Web module
A WAR file containing the view logics like JSPs, Servlets, Html contents. Every web module must have one Web Deployment descriptor placed inside "WEB-INF/
web.xml"
web.xml is a J2EE standard deployment descriptor. Among other settings, it has a set of elements for configuring security for the web application.
Note:
* An EAR file provides a convenient way to bundle up all pieces of a J2EE application. It may contain Java Module, WAR Module or an EJB Jar module.
An EAR can contain at least any one of these modules. EAR may contain more Modules as well.
* To bring your portal online in a production environment, it is first necessary to prepare your portal application. Typical preparation steps include modifying
deployment descriptors for the product, building the Enterprise archive (EAR) with all its pre-compiled classes, and deciding if you want to compress that EAR into
an archive or leave it exploded.

QUESTION 35
A managed server, myserver1, has a boot.properties file in the security directory. It was started with the startManageWeblogic.sh script(.cmd in windows) and his
boot.properties file was used for its startup credentials.
You just used the administration console to change all administrator passwords. To continue using boot.properties, what can you do?
A. This is not possible. A boot.properties file can be used only with the Administration Server.
B. Delete boot.properties. In the administration console, under the myserver configuration, select Generate Boot Identity file.
C. You need not do anything- The password in boot .properties was automatically updated by administration console when you changed the password.
D. Edit boot.propetties. Type over the encrypted password with the new password in clear text.
The next time myserver1 is started, it will encrypt the password in the file.
E. Delete boot .properties. Use the WLST encrypt () command to create a new boot.properties file containing the new password. Copy that file into the security
directory of myserver1
Correct Answer: D
Section: (none)
Explanation
If you install the WebLogic Server Examples component, the default user weblogic is created that has permission to start and stop WebLogic Server. The default
password is welcome1. If you change the password of the weblogic user, WebLogic Server does not automatically update this password in the boot.properties file,
which is located in the DOMAIN_NAME/servers/AdminServer/security directory.
If you change the password for user weblogic, you can use either of the following workarounds so that you can continue to boot a WebLogic Server instance via that
username and its new password:
* Remove the boot.properties file. Subsequently each time you start WebLogic Server, you are prompted for the username and password. The changed password
for the weblogic user will be accepted.
* Modify the existing boot.properties file, changing the username and password as follows:
username=weblogic
password=welcome1
Subsequently during the server startup process, the boot.properties file is encrypted again.

QUESTION 38
You monitor a running JDBC data source with the console and note the following values:
Current Capacity = 10
Current Capacity High Count = 20
Identify two plausible explanations for these metrics.
A. The pool size has increased.
B. The pool size has decreased.
C. The workload was higher than it is now.
D. The workload was lower than it is now.

E. The statement cache size is 10.
F. The statement cache size is 20.
Correct Answer: BC
Section: (none)
Explanation
The pool size has decreased from a maximum 20 to 10.
The workload has been 20. Now it is 10. The workload was higher.
Note: Current Capacity: The current count of JDBC connections in the connection pool in the data source.
Current Capacity High Count: Highest number of database connections available or in use (current capacity) in this instance of the data source since the data
source was deployed.
Note:
Incorrect answers:
E, F: The statement cache deals with statements. Current capacity and Current Capacity High Count deals with connections.
Statement Cache Size shows the total number of statements to cache for each connection in each instance of the data source. WebLogic Server can reuse
statements in the cache without reloading the statements, which can increase server performance. Each connection in the connection pool has its own cache of
statements.

Which three statements are true about the administration console?
A. The administration console cannot be disabled.
B. The context path of the administration console may be changed.
C. The administration console may be extended.
D. If a domain is in Development Mode, the administration console no longer requires an administration-level user when logging in.

E. If a domain is in Production Mode, access to the administration console must be made through secure port.
F. If the domain's Administration Port is enabled, access to the administration console must be made only through that port.
Correct Answer: BCF
Section: (none)
Explanation
B: The Console Context Path is an advance configuration option. The context path that you want to use in URLs that specify the Administration Console. Note:
Create a new WebLogic Server domain based on a template. Templates allow you to re-create an existing domain for use in another context, such as migrating a
domain containing an application under development to a production environment.
C: An Administration Console extension is a WAR file that contains the resources for a section of a WebLogic Portal Web application. When you deploy the
extension, the Administration Console creates an in-memory union of the files and directories in its WAR file with the files and directories in the extension WAR file.
Once the extension has been deployed, it is a full member of the Administration Console: it is secured by the WebLogic Server security realm, it can navigate to
other sections of the Administration Console, and if the extension modifies WebLogic Server resources, it participates in the change control process.
Incorrect answers:
A: Exposing the console in your production environment might be security issue. In those cases you can either disable the console or hide it. Needless to say if you
disable the console then your only option is to depend on command-line and scripting tools for any other administration activity or to even enable the console back.
But hiding will provide a level or security.
To disable the console:
In the admin console navigate to --> General --> Advanced Options --> Console Enabled. De-select that option to disable console (restart required).
To hide the cosole:
E: Access through a secure port is recommended, but not required:
The administration port requires all communication to be secured using SSL. By default, all servers in a domain use demonstration certificate files for SSL, but
these certificates are not appropriate for a production environment.

Identify three attributes of a WebLogic cluster.
A. Listen Address
B. Cluster Address
C. Cluster Factory
D. Messaging Mode
E. Servers
F. Targets
Correct Answer: BDE
Section: (none)
Explanation
WebLogic Cluster Attributes includes:
B: * ClusterAddress
Defines the address to be used by clients to connect to this cluster. This address may be either a DNS host name that maps to multiple IP addresses or a comma
separated list of single address host names or IP addresses. If network channels are configured, it is possible to set the cluster address on a per channel basis.
D: The Message Mode of a cluster can be either Unicast or multicast.
E: Managed Servers are included in a WebLogic cluster.
Note: The config.xml file is an XML document that describes the configuration of a WebLogic Server domain. config.xml consists of a series of XML elements. The
Domain element is the top- level element, and all elements in the Domain descend from the Domain element. The Domain element includes child elements, such
as the Server, Cluster, and Application elements. These child elements may have children of their own. For example, the Server element includes the child
elements WebServer, SSL and Log. The Application element includes the child elements EJBComponent and WebAppComponent.
Each element has one or more configurable attributes. An attribute defined in config.dtd has a corresponding attribute in the configuration API. For example, the
Server element has a ListenPort attribute, and likewise, the weblogic.management.configuration.ServerMBean has a ListenPort attribute. Configurable attributes are

readable and writable, that is, ServerMBean has a getListenPort and a setListenPort method.

QUESTION 46
A client accesses a web application named companystore that is running on WebLogic Server. After adding several items to the shopping cart, the host server
crashes. The client is automatically redirected to another server by a proxy, but the shopping cart is now empty. Which WebLogic Server feature would you enable
to remedy this situation?
A. Application Persistence
B. Message Persistence
C. Session Replication
D. Dynamic Failover
E. Stateful Pooling
Correct Answer: C
Section: (none)
Explanation
In order for a cluster to provide high availability it must be able to recover from service failures. In clusters that utilize Web servers with WebLogic proxy plug-ins, the
proxy plug-in handles failover transparently to the client. If a server fails, the plug-in locates the replicated HTTP session state on a secondary server and redirects
the client's request accordingly.

B. The Change Center is available only in a Production Mode domain.
C. The Change Center has a link to view any servers that need to be restarted.
D. After activating the changes to a server's configuration, you must always restart that server.
E. In a Development Mode domain, the configuration lock can be acquired automatically.
F. Changes must always be activated before they can be undone.
Correct Answer: ACE
Section: (none)
Explanation
A: You can view any changes that you have saved, but not yet activated, by clicking the View Changes and Restarts link in the Change Center.
C: The View Changes and Restarts link presents two tabs, Change List and Restart Checklist:
* The Change List tab presents all changes that have been saved, but not yet activated.
* The Restart Checklist lists all servers for which non-dynamic changes have been activated, but which require restarts before the changes become effective.
Incorrect:
D: is wrong because dynamic changes usually don't require a restart if that is all that was changed. If it were mix of dynamic and non-dynamic changes it would
require a restart.
F: is wrong because in production mode the change center has the "undo all changes" button so you don't have to activate the changes before you undo them.

E. WebLogic Server uses server machine assignments to help it choose servers in a cluster on which to replicate session state.
F. The machine's Cluster Weight attribute may be used by load balancers to help them determine how often to send requests to servers assigned to that machine.
Correct Answer: BE
Section: (none)
Explanation
B: The Administration Server uses the machine definition in conjunction with the Node Manager application to start remote WebLogic Server instances.
E: By default, WebLogic Server attempts to create session state replicas on a different machine than the one that hosts the primary session state. You can further
control where secondary states are placed using replication groups. A replication group is a preferred list of clustered servers to be used for storing session state
replicas.
Using the WebLogic Server Console, you can define unique machine names that will host individual server instances. These machine names can be associated
with new WebLogic Server instances to identify where the servers reside in your system. Machine names are generally used to indicate servers that run on the
same machine.

QUESTION 52
You received a signed certificate from a Certificate Authority and you wish to use the keytool command-line utility to store it in your keystore. Which command of
keytool would you us
A. genkey pair
B. import cert
C. gensockey
D. importkeystore
E. storepasswd
Correct Answer: B
Section: (none)
Explanation
B: keytool import
Reads the certificate or certificate chain (where the latter is supplied in a PKCS#7 formatted reply) from the file cert_file, and stores it in the keystore entry identified
by alias. If no file is given, the certificate or PKCS#7 reply is read from stdin. keytool can import X.509 v1, v2, and v3 certificates, and PKCS#7 formatted certificate
chains consisting of certificates of that type.
Incorrect answers:
A: keytool --genkey generates a key pair (a public key and associated private key). Wraps the public key into an X.509 v1 self-signed certificate, which is stored as
a single-element certificate chain. This certificate chain and the private key are stored in a new keystore entry identified by alias.
Description: Loads a trusted CA certificate into a keystore. If the keystore does not exist, it is created.

QUESTION 55
Which three statements are true about the default behavior of WebLogic Server proxy plug-ins?
A. The proxy will pin a client to a specific server if a session cookie is created.
B. The proxy fails over to another server if a connection or request times out.
C. The proxy distributes requests to cluster members based on their CPU usage.
D. The proxy dynamically learns the latest locations of cluster members.
E. The proxy always uses SSL, regardless of the client's protocol.
F. The proxy replicates session data to its backup proxy.
Correct Answer: ABD
Section: (none)
Explanation
A: When the HTTP client requests the servlet, HttpClusterServlet proxies the request to the WebLogic Server cluster. HttpClusterServlet maintains the list of all
servers in the cluster, and the load balancing logic to use when accessing the cluster. In the above example, HttpClusterServlet routes the client request to the
servlet hosted on WebLogic Server A. WebLogic Server A becomes the primary server hosting the client's servlet session. To provide failover services for the
servlet, the primary server replicates the client's servlet session state to a secondary WebLogic Server in the cluster. This ensures that a replica of the session state
exists even if the primary server fails (for example, due to a network failure). In the example above, Server B is selected as the secondary.
The servlet page is returned to the client through the HttpClusterServlet, and the client browser is instructed to write a cookie that lists the primary and secondary
locations of the servlet session state. If the client browser does not support cookies, WebLogic Server can use URL rewriting instead.
Figure, Accessing Servlets and JSPs using a Proxy:

B: In clusters that utilize Web servers with WebLogic proxy plug-ins, the proxy plug-in handles failover transparently to the client. If a server fails, the plug-in locates
the replicated HTTP session state on a secondary server and redirects the client's request accordingly.
D: The WebLogic proxy plug-in maintains a list of WebLogic Server instances that host a clustered servlet or JSP, and forwards HTTP requests to those instances
on a round-robin basis.
Incorrect answers:
C: The WebLogic proxy plug-in maintains a list of WebLogic Server instances that host a clustered servlet or JSP, and forwards HTTP requests to those instances
on a round-robin basis. This load balancing method is described in Round Robin Load Balancing. The plug-in also provides the logic necessary to locate the replica
of a client's HTTP session state if a WebLogic Server instance should fail.
F: SSL Parameters for Web Server Plug-ins
Parameter: SecureProxy
Default: OFF
Description: Set this parameter to ON to enable the use of the SSL protocol for all communication between the plug-in and WebLogic Server.

QUESTION 58
You are logged in to the administration console for a domain that is running in Development Mode. The domain configuration, you select Production Mode, Save,
and then Activate Changes.
Which two statements are true?
A. All running servers must be restarted.
B. Only the Administration Server must be restarted.
C. Auto-deployment will no longer be available for this domain.
D. This change may be made only through the Administration Server's secure port.
E. If you decide to go back to Development Mode, uncheck Production Mode in the administrate console.
Correct Answer: AC
Section: (none)
Explanation
C: auto deployment is not allowed in production mode only development mode.
Note 1:
All servers in a domain run either in development mode or production mode. To configure all servers in a domain to run in production mode:
1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit .
In the left pane of the Console, under Domain Structure, select the domain name.
2. Select Configuration > General and select the Production Mode check box.
3. Click Save, and then, to activate these changes, in the Change Center, click Activate Changes.
4. Shut down any servers that are currently running.
5. Invoke the domain's startWebLogic script.
The Administration Server starts in the new mode.
6. If the domain contains Managed Servers, start the Managed Servers.
Result
As each Managed Server starts, it refers to the mode of the Administration Server to determine its runtime mode.
Note 2: Once you have changed to production mode, whether by using a start command argument, the Console, or WLST, you cannot change back to development
mode without restarting the server.
By default auto deployment is turned off in Production Mode (however it can be later turned on).
Incorrect:
E: if you want to go back to development mode you must change the config.xml file and restart the admin server. The window shown below shows from
developemnt to production NOT production to development is allowed.
This is in development mode and you can change to production mode but in production mode this attribute states the word true.

QUESTION 61
You use a web browser to log in to a web application that is deployed to WebLogic Server. When you click link named "publish" on the site, an "Access Denied"
message appears. Which two statements must be true about this server's security configuration?
A. The application is not associated with any security roles.
B. Multiple security realms are active at the same time.
C. Your user account is a member of a group.
D. Your user account exists in an authentication provider.
E. A security policy is attached to the "publish" link URL.
Correct Answer: DE
Section: (none)
Explanation
D: You were able to log in to the web application that is deployed through WebLogic. In WebLogic Server, Authentication providers are used to prove the identity of
users or system processes.
This implies that your account exists in an authentication provider.
E: Extra security is needed to use the publish link. This could be explained by a security policy attached the publish Link URL.

QUESTION 62
You have set Server log Rotation criteria to either size or time. When a domain is in Production Mode, which statement is true?
A. Log files are rotated when the server restarts.
B. Log files are not rotated in Production Mode.
C. Log files are rotated only when the rotation criteria are met.
D. Log files are rotated when the rotation criteria are met or rotated when the server restarts
Correct Answer: C
Section: (none)
Explanation
By default, when you start a server instance in production mode, the server rotates its local log file whenever the file grows to 5000 kilobytes in size. It does not
rotate the local server log file when you start the server.
You can change these default settings for log file rotation. For example, you can change the file size at which the server rotates the log file or you can configure a
server to rotate log files based on a time interval. You can also specify the maximum number of rotated files that can accumulate. After the number of log files
reaches this number, subsequent file rotations delete the oldest log file and create a new log file with the latest suffix.

QUESTION 63
Which three methods does WebLogic provide to implement persistent JMS messaging?
A. Create a file store and assign it to a JMS server.
B. Create a JDBC store and assign it to a JMS server.
C. Configure a file store within a JMS module.
D. Configure the domain's default store.
E. Use the target server's default store.
Correct Answer: ABE
Section: (none)
Explanation
A: The main steps for creating a custom file store are as follows:
1.Create a directory where the file store's data will be persisted. 2.Create a custom file store and specify the directory location that you created. 3.Associate the
custom file store with the subsystem(s) or migratable target that will be accessing it, such as:
*For JMS servers, select the custom file store on the General Configuration page. *For Store-and-Forward agents, select the custom file store on the General
Configuration page. *For a Path Service, select the custom file store on the General Configuration page.
B: The main steps for creating a JDBC store are as follows:
Create a JDBC data source or multi data source to interface with the JDBC store. Create a JDBC store and associate it with the JDBC data source or multi data
source. It is highly recommended that you configure the Prefix option to a unique value for each configured JDBC store table.
Associate the JDBC store with the subsystem(s) that will be using it, such as:
For JMS servers, select the JDBC store on the General Configuration page. For Store-and-Forward agents, select the JDBC store on the General Configuration
page. For a Path Service, select the custom file store on the General Configuration page.
E: Each server instance, including the administration server, has a default persistent store that requires no configuration.
Note:
When a persistent message is sent, it is stored in the WebLogic Persistent Store. The persistent store provides a built-in, high-performance storage solution for
WebLogic Server subsystems and services that require persistence. For example, it can store persistent JMS messages or temporarily store messages sent using
the Store-and-Forward feature. The persistent store supports persistence to a file-based store or to a JDBC-enabled database.
Note 2: A persistent message is guaranteed to be delivered once-and-only-once. The message cannot be lost due to a JMS provider failure and it must not be
delivered twice. It is not considered sent until it has been safely written to a file or database. WebLogic JMS writes persistent messages to a WebLogic persistent
store (disk-base file or JDBC-accessible database) that is optionally targeted by each JMS server during configuration.
Reference: Using the WebLogic Persistent Store
QUESTION 64
Managed Server Independence enabled is not selected in the configuration of myserver1. Which statement is true?
A. Only the Node Manager can start myserver1

B. Only a local start script can start myserver1
C. Myserver1 cannot be part of a cluster.
D. The Administration Server must be available before starting myserver1
Correct Answer: D
Section: (none)
Explanation
To prevent the Administration Server from becoming a single point of failure, Managed Servers can always function without the presence a running Administration
Server. When a Managed Server starts, it contacts the Administration Server to retrieve its configuration information. If a Managed Server is unable to connect to
the specified Administration Server during startup, it can retrieve its configuration directly by reading a copy of the config.xml file and other files located on the
Managed Server's own file system.
A Managed Server that starts in this way is running in Managed Server Independence mode. In this mode, a server uses cached application files to deploy the
applications that are targeted to the server.

QUESTION 65
You have opened a terminal window (or a Window command prompt) to run a WLST script named weeklydeployer.py. You enter the following command:
Java weblogic.WLST weeklydeployer.py
Instead of the WLST initializing and the script running, however, you receive the NoClassDefFoundError java exception for weblogic/WLST.
What is the problem?
A. You forgot to set PATH to include the java executable.
B. There is an error in the code of the script.
C. You forgot to set CLASSPATH to include weblogic.jar.
D. You are not in the directory where weeklydeployer.py resides.
E. You should have omitted the ".py" in the file name; it is assumed by WLST.
F. You forgot to set PATH to include the WLST executable.
Correct Answer: C
Section: (none)
Explanation
To set up your environment for WLST:
1. Install and configure the WebLogic Server software
2. Add WebLogic Server classes to the CLASSPATH environment variable
Note: Although the process should be able to build the correct classpath by default, you might hit this issue in some cases. To overcome the problem, you must
explicitly set the classpath in the admin console accordingly.

QUESTION 66
You monitor a running JMS topic with the console and note the following values:
Consumers Current = 3
Message Current = 1
Message Pending = 0
These values do not change for several minutes. Which is the most plausible explanation?
A. Production on the topic has been paused.
B. A message arrived after a durable subscribe disconnected from the topic.
C. One of the consumers received a message but did not acknowledge it.
D. None of the consumers are durable subscribes.
Correct Answer: B
Section: (none)
Explanation
For durable subscriptions, WebLogic JMS stores a message in a persistent file or database until the message has been delivered to the subscribers or has expired,
even if those subscribers are not active at the time that the message is delivered.
Note #1: Durable subscriptions means that weblogic server will store the messages in a persistent store (i.e a file-store or a JDBC-store) until those messages are
delivered to the subscribers/listener. This technic helps weblogic server to make sure that the messages get delivered even if those subscribers/listeners are not
active at the time that the message is getting delivered.
As all of us know that in Topic's the senders/producers just send the messages to the topic and the receivers/listeners have subscribe them self to get those
messages, hence senders/producers does not have any concern if the messages are been received or not. However with this feature weblogic make sure all the
subscribers would get the messages as the messages gets stored in a persistence store.
Note #2:
* Consumers Current Count: Current number of consumers accessing this destination
* MessagesCurrentCount: The current number of messages in the destination. This does not include the pending messages.
* MessagesPendingCount: The number of pending messages in the destination.
Pending messages are over and above the current number of messages. A pending message is one that has either been sent in a transaction and not committed,
or that has been received and not committed or acknowledged.
Incorrect answers:
A: When a topic is paused for production, it prevents any new message production operations from both new and existing producers attached to that topic.
C: There is no pending message here. So there cannot be a message that a consumer has not acknowledged.
D: Non-durable messages are not stored.

QUESTION 67
Which statement best describes WebLog's default application staging behavior?
A. The Administration Sever distributes application files when the application is first accessed by a client.
B. The Administration Sever copied application files to a database that is shared with the Managed Servers.
C. The Managed Servers obtain application files from a disk that is shared with the Administration Server.
D. The Administration Sever distributes copied of application files over the network to the Managed Servers.
Correct Answer: D
Section: (none)
Explanation
Deployment Staging Mode: stage
Behavior: The Administration Server first copies the deployment unit source files to the staging directories of target servers specified by the Staging Directory Name
attribute.
The target servers then deploy using their local copy of the deployment files.
Note: The deployment staging mode determines how deployment files are made available to target servers that must deploy an application or standalone module.
WebLogic Server provides three different options for staging files: stage mode, nostage mode, and external_stage mode. The following table describes the
behavior and best practices for using the different deployment staging modes.

QUESTION 69
You create a system-wide JMS module named Payroll-JMS and set its default target to an existing cluster in your domain named PayrollCluster. Next, you add a
standard JMS topic to Payroll-JMS. To which are you permitted to target this topic?
A. the entire PayrollCluster
B. any single JMS server in the domain
C. any combination of member servers in Payrollcluster
D. several JMS servers targeted to PayrollCluster
Correct Answer: B
Section: (none)
Explanation
JMS system modules are owned by the Administrator, who can delete, modify, or add JMS system resources at any time. With the exception of standalone queue
and topic resources that must be targeted to a single JMS server, the connection factory, distributed destination, foreign server, and JMS SAF destination resources
in system modules can be made globally available by targeting them to server instances and clusters configured in the WebLogic domain. These resources are
therefore available to all applications deployed on the same targets and to client applications.
Note #1: JMS modules are application-related definitions that are independent of the domain environment. You create and manage JMS resources either as system
modules or as application modules.
System modules are globally available for targeting to servers and clusters configured in the domain, and therefore are available to all applications deployed on the
same targets and to client applications.
Note #2: JMS servers are environment-related configuration entities that act as management containers for the queues and topics in JMS modules that are targeted
to them. A JMS server's primary responsibility for its destinations is to maintain information on what persistent store is used for any persistent messages that arrive
on the destinations, and to maintain the states of durable subscribers created on the destinations. JMS servers also manage message paging on destinations, and,
optionally, can manage message and/or byte thresholds, as well as server-level quota for its targeted destinations. As a container for targeted destinations, any
configuration or run-time changes to a JMS server can affect all the destinations that it hosts.
