Oracle Oracle Certifications 1Z0-134 Questions & Answers

• Question 51:

  You are creating a new domain with WLST.

  Identify three parameters that can be customized with the setOption command. (Choose three.)

  A. the JDK that will be used to start the domain

  B. the domain name

  C. whether or not the domain will run in production mode

  D. the default persistent store type for the domain

  E. whether or not to automatically start the Node Manager

  F. the default diagnostic profile for the domain

  Correct Answer: ABC

  setOption sets options related to a domain creation or update.

  Syntax: setOption(optionName, optionValue)

  Option names include:

  *

  JavaHome--Home directory for the JVM to be used when starting the server. The default for this option depends on the platform on which you install WebLogic Server. Update JavaHome to point to the jre directory for the JDK that you are using for WebLogic Server.

  *

  DomainName--Name of the domain.

  *

  ServerStartMode--Mode to use when starting the server for the newly created domain. This value can be dev (development) or prod (production). This option defaults to dev.

• Question 52:

  Which two objects can be considered potential clients of a Node Manager? (Choose two.)

  A. an administration server

  B. a WLST session

  C. an HTTP server

  D. any other Node Manager

  E. a remote JMS client

  F. the weblogic.Deployer utility

  Correct Answer: AB

  A Node Manager client can be local or remote to the Node Managers with which it communicates. You access either version of Node Manager--the Java version or the script-based (SSH) version--from the following clients:

  A: an administration server

  B: WLST commands and scripts--WLST offline serves as a Node Manager command-line interface that can run in the absence of a running Administration Server.

• Question 53:

  In order to leverage replication and high availability features of your back-end database, among other benefits, you are configuring a JDBC TLOG store to persist transaction logs.

  Since something went wrong during the setup of the TLOG, you are reviewing the configuration considerations for TLOG.

  Which two guidelines are true for configuring JDBC TLOG stores? (Choose two.)

  A. Only one JDBC TLOG store can be configured per WebLogic Server.

  B. JDBC TLOG stores should only be configured for RAC databases.

  C. Only globally-scoped (not application-scoped) data sources can be targeted to a JDBC TLOG store.

  D. Multiple WebLogic Servers can share the same JDBC TLOG store.

  Correct Answer: AC

  A: Only one JDBC TLOG store can be configured per WebLogic Server. Conversely, multiple WebLogic Servers can not share a JDBC TLOG store.

  C: Only globally-scoped (not application-scoped) data sources can be targeted to a JDBC TLOG store.

• Question 54:

  Examine the domain diagram: You are asked to write a WLST script that will print the current available heap size for server04.

  

  Assuming: all servers are running you have just started an offline, interactive WLST session a domain-scoped node manager is running on each machine, listening o port :5556 the username/password "weblogic/Welcome1" maps to a valid domain administrator and Node Manager client

  Which two code options will accomplish this task? (Choose two.)

  A. connect(`weblogic',`Welcome1',`host00.acme.com:7001') domainRuntime() x = getMBean(`/ServerRuntimes/server04/JVMRuntime/server04') print x.getHeapFreeCurrent()

  B. connect(`weblogic',`Welcome1',`host02.acme.com:7201') serverRuntime() x = getMBean(`/JVMRuntime/server04') print x.getHeapFreeCurrent()

  C. connect(`weblogic',`Welcome1',`host00.acme.com:7001') serverRuntime() x = getMBean(`/JVMRuntime/server04') print x.getHeapFreeCurrent()

  D. nmConnect(`weblogic',`Welcome1',`host02.acme.com:5556') serverRuntimes() x=getMBean(`/server04/JVMRuntime/server04') print x.getHeapFreeCurrent()

  E. nmConnect(`weblogic',`Welcome1',`host00.acme.com:5556') domainRuntime() x=getMBean(`/ServerRuntimes/server04/JVMRuntime/server04') print x.getHeapFreeCurrent()

  Correct Answer: AB

• Question 55:

  You are managing a WebLogic domain that has the default built-in diagnostic module configured for each

  server in the domain.

  You have the following requirements:

  You want to capture metrics that are not collected by any of the built-in diagnostic modules.

  You want to continue capturing the metrics that are already captured by the existing built-in module.

  You want your configuration to persist after the server is restarted.

  What are two approaches you can apply to achieve this result? (Choose two.)

  A. Clone the built-in module, add now metrics to it, deactivate the existing module, and activate your new module.

  B. Leave the built-in module, create a new module and add metrics to it, and activate your new module alongside the built-in module.

  C. Leave the built-in module, create an external resource descriptor module and add metrics to it, and activate your new module alongside the built-in module.

  D. Remove the built-in module, create an external resource descriptor module and add built-in and new metrics to it, and activate your new module alongside the built-in module.

  Correct Answer: BC

  In a given domain, you can create multiple diagnostic system modules with distinct configurations. You can target multiple diagnostic system modules to any given server or cluster.

  Note: To configure and use the Instrumentation, Harvester, and Watch and Notification components at the server level, you must first create a system resource called a diagnostic system module, which will contain the configurations for all those components. The configuration of diagnostic system module is defined in a resource descriptor. A resource descriptor can be either configured or external.

• Question 56:

  You have a versioned application deployed in your production environment. You have been asked to troubleshoot why the most recent production redeployment appeared to allow the older version to retire too quickly.

  In this case, the application had active RMI clients, but their subsequent calls were directed to the newer version immediately rather than waiting for the expected five minutes defined by the retirement timeout argument. The script command was:

  java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic -password Welcome1 –redeploy –name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300

  You expected the older version to remain active (when there are active RMI clients) for five minutes after executing the production redeployment.

  Which modification should have been made to this command to ensure the older version remains active? (Choose the best answer.)

  A. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic -password Welcome1 –redeploy –name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300 –rmigraceperiod 300

  B. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic -password Welcome1 –redeploy –name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300 -keepsessions

  C. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic -password Welcome1 –redeploy –name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300 –timeout 300

  D. java weblogic.Deployer –adminurl http://localhost:7001 –user weblogic -password Welcome1 –redeploy –name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300 –remote

  Correct Answer: D

  The –remote argument indicates that weblogic.Deployer is not running on the same machine as the

  Administration Server, and that source paths specified in the command are valid for the Administration

  Server machine itself. If you do not use the -remote option, weblogic.Deployer assumes that all source

  paths are valid paths on the local machine.

  Incorrect Answers:

  weblogic.Deployer does not have arguments named rmigraceperiod, -keepsessions, or –timeout.

• Question 57:

  Which three types of information can an Extension Template contain? (Choose three.)

  A. JMS

  B. JDBC

  C. sample applications

  D. servers

  E. clusters

  F. machines

  G. administration username and password

  Correct Answer: ABC

  Optionally, you can define parameters for Java Message Service (JMS) in the Extension Template. Optionally, you can customize the Java Database Connectivity (JDBC) settings in the Extension Template. You can review and modify, if desired, the list of applications to be included in your extension template.

• Question 58:

  Under a normal startup scenario, a managed server contacts the administration server to get its configuration information.

  However in case the administration server is not available, which mechanism can be used by the managed server to start up successfully? (Choose the best answer.)

  A. Silent Mode

  B. Isolated Mode

  C. MSI Mode

  D. Cluster Mode

  Correct Answer: C

  When a Managed Server starts, it tries to contact the Administration Server to retrieve its configuration information. If a Managed Server cannot connect to the Administration Server during startup, it can retrieve its configuration by reading configuration and security files directly. A Managed Server that starts in this way is running in Managed Server Independence (MSI) mode

  B. \oracle_common\common\bin and temp_builder.sh

  C. \oracle_common\bin and config_builder.sh

  D. \oracle_common\bin and temp_builder.sh

  Correct Answer: A

• Question 60:

  You are deploying an application.

  Which two are common processes for all three staging modes? (Choose two.)

  A. The target server receives the deployment command, performs its internal preparation of the deployment, and performs the actual deployment.

  B. The administration server executes the deployment process on all targeted servers.

  C. The administration server copies all the files to each of the targeted servers.

  D. The administration server copies all the files to the appdeploy directory for the targeted servers.

  E. The administration server executes the unarchive process in each of the targeted servers.

  Correct Answer: BE

  Note: WebLogic Server provides three different options for staging files: stage mode, nostage mode, and external_stage mode.

  *

  In stage mode, the Administration Server copies the deployment files from their original location on the Administration Server machine to the staging directories of each target server.

  *

  In nostage mode, the Administration Server does not copy the archive files from their source location. Instead, each target server must access the archive files from a single source directory for deployment. The staging directory of target servers is ignored for nostage deployments.

  *

  External_stage mode is similar to stage mode, in that target servers deploy using local copies of the deployment files. However, the Administration Server does not automatically copy the deployment files to targeted servers in external_stage mode; instead, you must copy the files to the staging directory of each target server before deployment.

  Incorrect Answers:

  C, D: In the external_stage and Nostage mode the Administration Server does not copy deployment files.
