Question 2

Which is true when an administrator properly updates a single file within an application?


  1. The administrator can use apartial application update.
  2. The administrator must redeploy the full application file.
  3. The administrator can manually update the file on the file system.
  4. The administrator must uninstall the application, and then, reinstall with the updated application file.
Correct answer: C



Question 3

Which is true about software repositories for IBM Installation Manager?


  1. Repositories must be local.
  2. Repositories must be online.
  3. Repositories can be either local or online.
  4. Repositories are only in the media package.
Correct answer: C
Explanation:
IBM Installation Manager is a single installation program that can use remote or local software repositories to install,modify, or update certain IBM products. It determines and shows available packages, checks prerequisites and interdependencies, and installs or modifies the selected packages. You also use IBM Installation Manager to uninstall the packages that it installed.References: http://www-01.ibm.com/support/docview.wss?uid=swg24023498

Question 4

An administrator installed an enterprise application in fast mode and noticed that the application is failing because J2EE roles have not been mapped.
How can this issue be resolved?


  1. Re-deploy the application.
  2. Request that the application developer create an enhanced .ear file which has roles mapped, and deploy the enhanced .ear file.
  3. Map a security role to the user/group for the application using the Integrated Solutions Console, save changes, and restart the application.
  4. Map a security role to the user runAs roles for the application using the Integrated Solutions Console, save changes, and restart the application.
Correct answer: C
Explanation:
WSRR defines J2EE roles that must be mapped to user or group principals. This can be done by using the WebSphere Administration ConsoleReferences: https://www.ibm.com/support/knowledgecenter/en/SSWLGF_8.5.6/com.ibm.sr.doc/twsr_configrn_userroles08.html

Question 5

An administrator needs to resolve port conflicts after creating a managed node using the Profile Management Tool.
Which supported method can be used to resolve the port conflicts?


  1. Editserverindex.xml.
  2. UseupdatePorts.ant.
  3. Use Profile Port Checker tool and set ports.
  4. UsemanageProfiletool and set port range on the profile.
Correct answer: B
Explanation:
If you discover ports conflicts, then you can reassign ports manually. To reassign ports, run the updatePorts.ant file by using the ws_ant script.References: https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.base.doc/ae/tpro_instancessaappserv.html

Question 6

An administrator notices that the Message Driven Beans (MDBs) are slow to complete, and decides to increase the 'Maximum concurrent MDB invocations per endpoint'.
Which thread pool should be tuned to ensure it can run the maximum number of MDBs without waiting?


  1. Default
  2. WebContainer
  3. SIBJMSRAThreadPool
  4. WMQJCAResourceAdapter
Correct answer: D
Explanation:
The thread pool WMQJCAResourceAdapter is referenced by the WebSphere MQ (WMQ) resource adapter inbound delivery to MDB's. WhenWebSphere MQ resource adapter is used in conjunction with the activation specs, the resource adapter's Work Manager uses the values defined for the WMQJCAResourceAdapter for utilizing the total number of threads defined.Ideally the default values provides for the WMQJCAResourceAdapter will be sufficient for the resource adapter. But in case there is an heavy load on the system processing huge number of messages, you can increase the maximum number of threads the thread pool can hold.References: http://www-01.ibm.com/support/docview.wss?uid=swg21383363

Question 7

What determines which On Demand Routers (ODRs) a Web server forwards requests to?


  1. The default order in theODR_Module_Routing_Poilicy.xml.
  2. The configuration scope determines which ODRs are included inhttpd.conf.
  3. The configuration scope determines which ODRs are included inplugin-cfg.xml.
  4. The configuration scope determines which ODRs are included inHTTPplugin-cfg.xml.
Correct answer: C
Explanation:
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin- cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.References: https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/twve_odr.html

Question 8

An administrator would like to uninstall an instance of a multiple instance installation via response file.
How does the administrator ensure that the correct instance is uninstalled?


  1. All the features must be listed.
  2. The profile ID must point to the correct instance.
  3. The offering IDmust point to the correct instance.
  4. The repository location must point to the correct instance.
Correct answer: D

Question 9

An administrator configures an IBM DB2data source at cell scope. The environment variable DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope. The data source test connection on one node succeeds, but fails on the other node with java.lang.ClassNotFoundException:com.ibm.db2.jcc.DB2ConnectionPoolDataSource.
Which of the below is the likely cause for the exception?


  1. The data source is configured at cell scope.
  2. Multiple driver JARs are installed on the second node.
  3. DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope.
  4. A different version of the JDBC driver JAR does not exist on the second node.
Correct answer: C
Explanation:
Check that the variable is correctly defined at the scope where the JDBCProvider/DataSource is defined.Note: At runtime, WebSphere Application Server invokes a physical data source by resolving the appropriate variable at a level where one of thefollowing criteria exists: The scope of the variable can contain the data source configuration; that is, the variable has the larger scope.The variable and the data source have identical scopes.Application Server meets these conditions by attempting to resolve the variable at each level of the scope spectrum. That is, the product tries to resolve the variable in the server scope, then the cluster scope, then the node scope, and lastly the cell scope.References: https://www.ibm.com/support/knowledgecenter/SSAW57_8.0.0/com.ibm.websphere.nd.doc/info/ae/ae/cdat_testcon.html

Question 10

What data source property can an administrator configure to minimize the chances of encountering StaleConnectionExceptions?


  1. Minimum connections = 0
  2. Reap Timeout < Unused Timeout
  3. Purge Policy = FailingConnectionOnly
  4. Unused Timeout > Half firewall timeout
Correct answer: A
Explanation:
Explanation: The configuration options below help minimize the chances of encounteringStaleConnectionExceptions by helping to ensure that your WebSphere Application Server maintains control of database connections, specifically, the only one closing them, rather than other components in your network:The datasource MIN connections should beset to 0. By setting a MIN > 0, you are telling the application server that this number of connections will be valid for the life of the application server JVM. Unless you can guarantee the MIN number of connections will never be timed out or dropped, setting a MIN will cause a StaleConnectionException when the connection becomes invalid.References: https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/websphere_application_server_staleconnectionexceptions?lang=en
