• Question 61:

  An application deployed to a multi-node cluster is reported to have slowness and hung threads. A system administrator is asked to review the logs on each node and identify if the hung threads are a false alarm. How can the administrator determine that the hung threads are a false alarm? Analyze the:

  A. ffdc logs.
  B. SystemErr.log.
  C. SystemOut.log.
  D. native_stderr.log.
  C. SystemOut.log.

• Question 62:

  There are many applications deployed in a large WebSphere Application Server cluster. A system administrator is required to give Configuration role access to a developer for a single application deployed in that cluster. How should the administrator meet this requirement and restrict Configuration role access for a single application?

  A. Create a J2C authentication alias for that developer.
  B. Create an Administrative user role and provide Configuration access to the developer.
  C. Create an Administrative group role and provide Configuration access to the developer.
  D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configuration access to the developer.
  A. Create a J2C authentication alias for that developer.

• Question 63:

  Within a WebSphere Application Server Network Deployment cell, a system administrator needs to write a script to determine if a particular server is stopped. It is important that the wsadmin script explicitly return a status of stopped as opposed to just failing.

  What wsadmin object should the administrator use to write this script?

  A. AdminApp
  B. AdminTask
  C. AdminConfig
  D. AdminControl
  D. AdminControl

• Question 64:

  A system administrator suspects that the slow performance of an application might be caused by lock contention. To debug this further, what can the administrator do using IBM Support Assistant?

  A. Analyze the running server using IBM Monitoring and Diagnostic Tools for Java -Health center.
  B. Collect a java core and analyze it using IBM Monitoring and Diagnostic Tools for Java - Health Center.
  C. Collect three thread dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java - Dump Analyzer.
  D. Collect three system dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java - Memory Analyzer.
  A. Analyze the running server using IBM Monitoring and Diagnostic Tools for Java -Health center.

• Question 65:

  A system administrator is required to monitor the application server logs for heap memory issues and determine if the heap memory usage is reaching close to 70% of the maximum heap. The application server is configured with an initial heap of 256 MB and a max heap of 1 GB.

  How should the administrator determine if the application server is utilizing 70% of the max allocated heap memory?

  A. Check the System logs for Out Of Memory Errors. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
  B. Configure WebSphere Application Server to enable verbose garbage collection. Analyze the garbage collection cycles in the native logs.
  C. Configure Initial heap to be equal to the max heap. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
  D. Configure WebSphere Application Server to increase max heap. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
  A. Check the System logs for Out Of Memory Errors. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
