Study with C2180-318 Actual Test Questions

A system administrator needs to control which staff members have access to manage certain application servers. They choose to use fine grained control and map the staffmembers to only those specific application servers to which they need access. What does the system administrator need to do to accomplish this?

• A. Use anAdministrative Authorization Group to map the staff members and roles to the application servers.
• B. Add custom properties to each of the application servers with role mappings for each staff member
• C. Create a custom user registry which prevents authorization requests to the application servers not in the desired list.
• D. Create a security domain and add the application servers with the staff members in the role definitions.

A system administrator has made a configuration change to the cell repository that needs to replicate to a node. The node agent of the node is currently in stopped state. What must the system administrator do to synchronize thenodes with the deployment manager?

• A. Run the Synchronize function from administrative console by selecting the out of sync node.
• B. Execute the command syncNode [options]
• C. Restart the deployment manager.
• D. Invoke theSync operation on NodeSync MBean from wsadmin connected to deployment manager.

In a production environment, a system administrator tuned the data source statement cache to optimize the processing of prepared statements and callable statements by caching those statements that are not used in an active connection. When the cache is full, old entries in the cache are discarded. The administrator would like to get statistics on the number of statements discarded from the cache to determine how to minimizecache discards. How can the system administrator obtain this information?

• A. Use the Tivoli Performance Viewer.
• B. Use the IBM Support Assistant Data Collector.
• C. Configure HPEL and examine the log files.
• D. Enable request metrics.

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.

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