IBM WebSphere Application Server Network Deployment V8.5.5 and Liberty Profile, System Administration Sample Questions:
Question 1
A system administrator is asked by a development team to monitor the performance of a newly deployed EJB application. The administrator noticed that the heap size of the application server is growing.
What should the administrator do to fix the problem using ORB settings?
A. Ensure that Process embedded configurations is not selected when exporting the EAR.
B. Disable the application scoped resources in the application deployment descriptor.
C. Use J2EE managed object MBeans.
D. Enable the pass by reference option.
Question 2
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. Configure Initial heap to be equal to the max heap.Trigger a heap dump from the
Integrated Solutions Console (ISC).Analyze the heap dump.
B. Configure WebSphere Application Server to increase max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
C. Configure WebSphere Application Server to enable verbose garbage collection.Analyze the garbage collection cycles in the native logs.
D. Check the System logs for OutOfMemoryErrors.Trigger a heap dump from the
Integrated Solutions Console (ISC).Analyze the heap dump.
Question 3
A performance test team was testing the capacity of concurrent users of a web application deployed on a multi-processor server.
While testing 250 concurrent users, the administrator discovers connections to the database are failing.
In response, a system administrator increased the connection pool to the maximum limit which the database allows and increased the prepared statement cache size.
The test passed, but the application response time was slower.
How should the system administrator tune the data source properties to improve the application response time?
A. Decrease number of free pool partitions.
B. Decrease the prepared statement cache size.
C. Change connection pools purge policy.
D. Decrease connection pool reap time.
Question 4
While monitoring a cluster in the cell, the administrator notices that one server in the cluster periodically loses connections to the database. When this happens, requests to the server have a significantly decreased response time and various error conditions are listed in the log files for the server. Since the error codes are returned quickly, the server starts returning responses faster than the average service times for the application. Due to this, the weight for the server is increased and a large percentage of incoming requests are being routed to the erroneous server and the server is getting overloaded with requests.
How can the administrator detect these conditions in the future and take action to prevent this problem?
A. Monitor the JVM heap usage to determine a new server weight.
B. Configure the storm drain health policy.
C. Enable the PMI Extended statistic set and use the Connection Pool summary report.
D. Configure the on demand router (ODR) transport chain to tune inbound connections.
Question 5
A WebSphere Application Server cell was configured with a deployment manager node and a custom node. An operator manually changed some configuration files in the custom node, and the node became out of synch with the master repository.
The system administrator used the Synchronize button in the system administration session of the Integrated Solutions Console (ISC) to try to resynchronize the node, but the node remained out of sync.
What should the administrator do to fix it?
A. Recreate the custom profile with the same name without deleting the node.
B. Use the Full Resynchronize button.
C. Invoke "sync" operation on NodeSync MBean.
D. Manually copy all the deployment manager configuration files to the custom node.
