A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs. The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run.

How can the administrator decrease the size and remove some of the content from the shared resources directory?

A. Manually delete content from the directory.

B. During an update, create a new shared resources directory.

C. Clear the Delete Saved Files option for the Installation Manager.

D. Set the preserve Downloaded Artifacts preference to false.

A system administrator has created a cluster containing two servers in a same node. The administrator did not select the option Generate unique HTTP ports during the creation of the cluster members. After the cluster creation, the administrator changed the HTTP port of the second cluster member to 9081.

Testing the servers using the snoop servlet directly to the server's HTTP port, the administrator got the following error message for the second server:

How can the administrator fix this problem?

A. Regenerate and propagate the HTTP plug-in.

B. Add the port 9081 to the default_host alias.

C. Create a new virtual host alias at the cell level for the port 9081.

D. Edit the server.xml for the second server and add the port 9081.

A WebSphere system administrator needs to install the Installation Manager (IM) on an unmanaged node on a host named . The deployment manager is running on a host named .

What step must the administrator take before submitting a job from the Integrated Solutions Console (ISC) to install the IM on ?

A. Install a node agent on .

B. Install the job manager on .

C. Start the job manager on .

D. Register as a target for job manager.

A system administrator is asked by a development team to monitor the performance of a newly deployed EJB application. The administrator noticed that the heap size of the application server is growing.

What should the administrator do to fix the problem using ORB settings?

A. Use J2EE managed object MBeans.

B. Enable the pass by reference option.

C. Disable the application scoped resources in the application deployment descriptor.

D. Ensure that Process embedded configurations is not selected when exporting the EAR.

The application placement controller has been configured with elasticity mode enabled. Intermittently, all instances of a dynamic cluster are removed. After further review, the system administrator noticed that it occurs during peak load on another dynamic cluster.

The administrator wants to keep at least one instance available. Which configuration is needed in the dynamic clusters?

A. Enable application lazy start with elasticity mode.

B. Set the proactiveIdleStop custom property to true.

C. Set the Number of instances to a value greater than zero.

D. Disable the option "If other dynamic clusters need resources, stop all instances of this cluster during periods of inactivity".

A WebSphere Application Server cell was configured with a deployment manager node and a custom node. An operator manually changed some configuration files in the custom node, and the node became out of synch with the master repository.

The system administrator used the Synchronize button in the system administration session of the Integrated Solutions Console (ISC) to try to resynchronize the node, but the node remained out of sync.

What should the administrator do to fix it?

A. Use the Full Resynchronize button.

B. Invoke "sync" operation on NodeSync MBean.

C. Recreate the custom profile with the same name without deleting the node.

D. Manually copy all the deployment manager configuration files to the custom node.

A system administrator has installed WebSphere Application Server Network Deployment V8.5.5 using the silent installation process and needs the verify that the installation completed successfully.

What does the administrator need to do to verify a successful installation?

A. Launch the Installation Manager GUI, verify the installation by going to File -> View Installed Packages.

B. Run the command IBMIM listInstalledPackages and check that the appropriate WebSphere Application Server package is listed.

C. Check for INSTCONFSUCCESS message at the end of the log.txt file.

D. Use the installver command to compare the checksum of the product file to the correct checksum value in the bill-of-materials file and make sure that the checksums match.

A system administrator needs to trigger a javacore only when a java,net.SocketTimeoutException is encountered in real time.

What does the administrator have to configure to trigger the javacore dump?

A. Configure the JAVA_DUMP_OPTS environment variable to capture javacore for ANYSIGNAL and all exceptions.

B. Configure an -Xdump:java Generic JVM argument on WebSphere Application Server with the filter for java.net.SocketTimeoutException.

C. Code wsadmin script to capture javacore and then execute it after the java.net.SocketTimeoutException has been encountered.

D. Use the log filter in HPEL to monitor for java.net.SocketTimeoutException and then gather a javacore dump from the Integrated Solutions Console (ISC).

An EJB application posts a request message into a JMS destination and waits for a response message on a different JMS destination. To correlate the response message to the request message, the application uses the JMS correlationId of the message. The application waits up to five seconds for a response before timing out the request.

A Message Driven Bean (MDB) running on a different cluster is responsible for consuming the request message, process it and post a response message.

The destinations are defined in a Service Integration Bus (SIB) within the cell. Intermittent timeout exceptions have occurred for the requester application. How can a system administrator correlate and analyze the debug information from both requester and consumer applications?

A. Enable High Performance Extensible Logging (HPEL).Use HPEL logViewer command to see debug information.

B. Enable a diagnostic trace in both requester and consumer servers.Use the Integrated Solutions Console (ISC) to set the admin=all trace.Analyze the trace.

C. Enable High Performance Extensible Logging (HPEL).Enable Cross Component Trace (XCT) to include request IDs in log and trace records.Use HPEL logViewer command with appropriate filters to see debug information.

D. Using the Integrated Solutions Console (ISC), browse the request message that has timed out and look for any key application data.Search for exceptions using the key application data in both requester and consumer in native_stderr.log and native_stdout.log.

A system administrator needs to install WebSphere Application Server Network Deployment V8.5.5 multiple times and would like to automate the task of installing the product. The administrator wants to create a response file based on an initial installation and use this for future installations.

How can the administrator accomplish this task?

A. Use the IBM Packaging Utility.

B. Use the Installation Manager console mode.

C. Complete a silent installation with the -log option.

D. Start the Installation Manager GUI with the -record option.
