  B. Determine what could be causing the HTTP status code 620.

  C. Verify Login.jsp can be found in the document root directory of the IHS.

  D. Check the server's SystemOut.log file to see what errors occurred around the same time.

• Question 22:

  A system administrator has enabled the HPEL mode on an application server, but has disabled the HPEL text log to improve performance.

  How can the administrator view only the messages that were streamed to System.out and System.err by a single server thread?

  A. Use a text editor to open a log file in the server's logdata directory, and search for the thread ID.

  B. Use the Log Analyzer to import the SystemOut.log file for the server and search on the thread ID.

  C. Use the Integration Solutions Console (ISC) Log Viewer to select a thread and then click the "Show Only Selected Threads" button.

  B. Ensure that all connections taken from the data source are returned to the pool.

  C. Determine why the collection class increases in size and consumes memory.

  D. Modify the application so it uses stateless instead of stateful session beans to conserve the heap.

  Correct Answer: C

• Question 24:

  An application developer needs to know the SOAP_CONNECTOR_ADDRESS for their development application server. The Integrated Solutions Console (ISC) is unavailable because the Deployment Manager server is down for maintenance.

  How can the system administrator determine the proper port number for the developer? Search for SOAP_CONNECTOR_ADDRESS in the:

  A. server.xml

  B. serverindex.xml

  C. resources.xml

  D. virtualhosts.xml

  Correct Answer: B

• Question 25:

  A Java EE application is deployed to a horizontal cluster and makes use of HTTP session objects. The administrator is required to ensure failover of these session objects, and chooses to implement memory-to-memory replication. To maximize chances of successful failover, how should the administrator configure the replication?

  A. Select Entire domain for the number of replicas.

  B. Select Single replica and select the default tuning parameter.

  C. Select Single replica and select "Very high" for the tuning parameter.

  D. Specify at least 3 replicas and select "Very high" for the tuning parameter.

  Correct Answer: A

  C. Implement Secure Shell (SSH) communication.

  D. Configure Secure Sockets Layer (SSL) transport.

  Correct Answer: D

• Question 28:

  B. Remove the cluster members and delete the cluster.

  C. Uninstall the application and delete the cluster.

  D. Uninstall the application, remove the cluster members and delete the cluster.

  Correct Answer: A

• Question 29:

  A cluster is a member of a service integration bus (SIBus) and is configured with the high availability messaging engine policy.

  How should a system administrator configure JMS messaging so that message-driven beans (MDBs) on all cluster members can get messages?

  A. Enable the JMS activation specification option: Always activate MDBs in all servers.

  B. Enable the JMS destination option: Do not prefer a local queue point over other queue points.

  C. Set the scope of all JMS destinations to the cluster that is a member of the SIBus.

  D. Set the scope of the JMS connection factory to the cluster that is a member of the SIBus.

  Correct Answer: A

• Question 30:

  A. Enable protocol transformation between buses.

  B. Add a cluster to the bus and create multiple messaging engines.

  C. Use a proxy server to route messages to multiple messaging engines.

  D. Create a mediation to manage the messaging work load across servers.

  Correct Answer: B
