• Question 102:

  Consider a cluster of four servers: ServerA, ServerB, ServerC, and ServerD. The cluster hosts a web application and is accessed using a proxy pug-in. This web application is configured to use in-memory session replication. A user is directed to ServerA. An HTTP session is established on ServerA and is also replicated to ServerC. If ServerA subsequently fails, which server will this user be redirected to?

  A. none; the user will receive an error message
  B. ServerB
  C. ServerC
  D. ServerD
  E. Any other available server
  C. ServerC

  To support automatic failover for servlet and JSP HTTP session states, WebLogic Server replicates the session state in memory. WebLogic Server creates a primary session state on the server to which the client first connects, and a secondary replica on another WebLogic Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server that hosts the servlet fails. The process of copying a session state from one server instance to another is called in-memory replication.

• Question 103:

  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.
  A. Create two subdeployments within the JMS module.

  ---

  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 104:

  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
  C. Log files are rotated only when the rotation criteria are met.

  ---

  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 105:

  Which answer best describes how you can start the Java-based version of the Node Manager?

  A. W1scontrol.sh (.cmd in Windows)
  B. Wisifconfig.sh (.cmd in Windows)
  C. startNodeManager.sh (.cmd in Windows)
  D. startNM.sh (.cmd in Windows)
  C. startNodeManager.sh (.cmd in Windows)

  ---

  Although running Node Manager as an operating system service is recommended, you can also start Node Manager manually at the command prompt or with a script. Use startNodeManager.cmd on Windows systems and startNodeManager.sh on UNIX systems.

• Question 106:

  Identify three ways to create a domain template.

  A. Administration console
  B. Domain Template Builder
  C. unpack command
  D. pack command
  E. Node Manager
  F. WLST
  G. Configuration Wizard
  B. Domain Template Builder
  D. pack command
  F. WLST

  ---

  There are three ways to create domain templates:

  *

  Domain Template Builder (config_builder.sh under WL_HOME/common/bin) Go to Start Menu->All programs->weblogic10gR3->Tools->Domain Template Builder

  *

  pack command The pack command creates a template archive (.jar) file that contains a snapshot of either an entire domain or a subset of a domain. You can use a template that contains a subset of a domain to create a Managed Server domain directory hierarchy on a remote machine.

  *

  WLST offline command line tool

• Question 107:

  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.
  D. The Administration Sever distributes copied of application files over the network to the Managed Servers.

  ---

  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.

  C. Java Standard Identity and Custom Trust
  D. Custom Identity and Demo Trust
  E. Custom Identity and Custom Trust
  F. Custom Identity and Command Line Trust
  A. Demo Identity and Demo Trust
  E. Custom Identity and Custom Trust
  F. Custom Identity and Command Line Trust

• Question 109:

  Identify two methods for utilizing WebLogic Server's production redeployment feature.

  A. Specify a version identifier when deploying the application.
  B. Include a version identifier in the application's manifest file.
  C. Provide a version identifier when running the Plan Generator tool.
  D. Include a unique context root in the application's descriptor files.
  A. Specify a version identifier when deploying the application.
  B. Include a version identifier in the application's manifest file.

  ---

  A: If you are testing the production redeployment feature, or you want to use production redeployment with an application that does not include a version string in the manifest file, specify a unique version string by using the -appversion option when deploying or redeploying an application

  B: To assign a version identifier to an application, BEA recommends that you store a unique version string directly in the MANIFEST.MF file of the EAR or WAR being deployed.

• Question 110:

  While creating a new domain in the Configuration Wizard, there are two types of machines that may be configured. Identify them.

  A. Machine and Windows machine
  B. administrator machine and managed machine
  C. machine and Unix machine
  D. stand-alone machine and cluster machine
  E. RDBMS machine and LDAP machine
  B. administrator machine and managed machine

  Administrator machine:

  The Choose the Administration Server window prompts you to designate a server as the Administration Server. This window is displayed automatically only if the selected template includes multiple servers that are not assigned to clusters.

  To choose the Administration Server:

  1.

  From the list of Available Servers, select the server that you want to designate as the Administration Server. The Administration Server cannot be assigned to a cluster.

  The Server Details area displays detailed information about the selected server. By default, the currently assigned Administration Server is selected.

  2.

  Select Next to proceed to the next configuration window.

  The Configure the Administration Server and Configure Managed Server(s) windows are updated to reflect your changes.

  Managed machine:

  The minimum requirement for your domain is a single Administration Server on a single machine. In addition, however, you have the option of configuring other resources to be managed by the Administration Server and distributing them

  across multiple machines.

  Specifically, you can:

  *

  Add, change, or delete Managed Servers

  *

  Add, change, or delete clusters

  *

  Group Managed Servers into clusters, or change current groupings

  *

  Assign servers to machines, or change current assignments

  Note: The Managed Servers, Clusters, and Machines Options window prompts you to specify whether you want to distribute your WebLogic configuration across Managed Servers, clusters, and physical machines

  Note 2:

  The Configure Managed Servers window prompts you to provide the configuration information for one or more Managed Servers. Production environments typically deploy one or more Managed Servers, in addition to the Administration

  Server, to host enterprise applications.
