IBM WebSphere Application Server Network Deployment V8.5, Core Administration Sample Questions:

1. A system administrator is monitoringa web application and needs to find the slowest JSP page when a typical client load is run against the server. How can the system administrator find it?

A) Use the HPEL Log Viewer to view traces.
B) Use the Tivoli Performance Viewer (TPV) and view the Servlet Summary reports.
C) Analyze the thread dump.
D) Use the Log Analyzer toview the SystemOut logs

2. An administrator needs to move an application from a Liberty profile development environment to a production Network Deployment cell. What steps should the administrator take to deploy the application in the production cell?

A) Use the migration tool to generate the customizedand automated wsadmin script.
B) Use the "Release" functionality in the administrative console and point it to the server.xml file of the development Liberty profile.
C) Deploy the application EAR file through the deployment manager and define the resources defined in the server.xml.
D) Use the enhanced EAR generated by the Liberty profile ensuring that the resources used by the Liberty profile are used by the deployment manager.

3. A system administrator manages a WebSphere Application Server environment which uses a Federated Repository consisting ofmultiple LDAP servers. The first LDAP server is the corporate, highly-available LDAP server and contains most of the users. The second LDAP server contains only the administrative users and is run on a local system which is restarted regularly. To maximize the availability of the Federated Repository, what should the system administrator do?

A) Set the second LDAP server as a backup server.
B) Add both LDAP servers to the High Availability Manager's core group.
C) Use a TAI (Trust Association Interceptor)to aggregate the LDAP servers.
D) Enable Allow operations if some of the repositories are down.

4. A system administrator notices that only one of the two available clustermembers is receiving HTTP requests. The http_plugin.log shows that the other cluster member is constantly marked down even though it is up and running. What should the system administrator do to follow the request process flow to help diagnose the problem?

A) Change LogLevel="Trace" in the plugin-cfg.xml file and view the http_plugin.log
B) Use the HPEL Log Viewer to select a thread and click the "Show Only Selected Threads" button.
C) Use IBM Support Assistant to analyze the HTTP server error log.
D) Use the Log Analyzer to import the HTTP server access log.

5. A system administrator has configured a clustered environment where session persistence
is configured. While tuning the environment, the administrator enables verbose garbage collection. Now the administrator is seeing a high CPU usage for the servers in the cluster and begins seeing out-of-memory exceptions in the log files. How can the system administrator diagnose what is accumulating in the memory and causing the out-of-memory exceptions?

A) Enable High Performance Extensible Logging (HPEL).
B) Disable verbose garbagecollection and compare the before and after verbose garbage collection statistics.
C) Use the Garbage Collection and Memory Visualizer tool in the IBM Support Assistant.
D) Examine the verbose garbage collection statistics in the SystemOut.log files.
