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?

1. Create a J2C authentication alias for that developer.

2. Create an Administrative user role and provide Configuration access to the developer.

3. Create an Administrative group role and provide Configuration access to the developer.

4. 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.

Answer: A

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?

1. Check the System logs for Out Of Memory Errors.

   Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.

2. Configure WebSphere Application Server to enable verbose garbage collection. Analyze the garbage collection cycles in the native logs.

3. Configure Initial heap to be equal to the max heap.

   Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.

4. Configure WebSphere Application Server to increase max heap. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
