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

1. A system administrator needs to define an alternate security configuration for one of the clusters in a cell. As a whole, the cell uses a Federated Repository. The cluster in question needs to define a specific stand-alone LDAP server. How could the system administrator accomplish these requirements?

A) Install and configure a TAI(Trust Association Interceptor) which disables authentication calls coming in just for the cluster.
B) Configure a security domain for the stand-alone LDAP server. Add the applications in the cluster to the security domain.
C) Create a new security domain mapped to a scope of the cluster. Then assign the security attributes for the User Realm to use the stand-alone LDAP server.
D) Use a custom registry which checks with the stand-alone LDAP server for authentication. Ensure that the custom registry is enabled only when calls are made from the cluster.

2. A system administrator needs toconfigure Single Sign-on (SSO) using LTPA for an application which will run in two cells. What is one of the key steps in configuring cross cell authentication?

A) Put the name of the second cell in the "Domain name" field of the first cell.
B) Enable the "Interoperability mode" in SSO configuration screen.
C) Enable the "Requires SSL" feature in SSO configuration screen.
D) Export the LTPA keys from one cell and import them into the other.

3. An enterprise application needs to be deployed into a production WebSphere Application Server environment. The EAR contains application scoped resources which will conflict with the resourcedefinitions that already exist in the federated environment.How can the system administrator ensure that the enterprise application uses only the already existing resources?

A) Verify that the classpath does not include the folder containing the application scoped resources.
B) Make sure that Process embedded configuration is not selected during the deploy process.
C) Change the scoping for the existing resources to the cell level.
D) Check that the EAR file is not in the application server classpath.

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) Use the Log Analyzer to import the HTTP server access 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) Change LogLevel="Trace" in the plugin-cfg.xml file and view the http_plugin.log

5. A system administrator needs to create a diagnostic trace for an application server which has a problem that occurs only infrequently. The desire is to limit the amount of space taken up by the trace output file but still ensure that the log includes the trace information recorded during the problem. What should the system administrator do to accomplish these goals?

A) Limit the Maximum Number of Historical Files to one.
B) Configure the trace output to use a memory buffer and do a manual dump when the problem occurs.
C) Reduce the Maximum File Size to an amount just larger than the required trace log.
D) Use the First Failure Data Capture (FFDC)feature to ensure the trace log is only capture on the first instance of the problem.
