Question: 1

A system administrator needs to configure a JDBC provider and a data source for an application in a clustered environment. The administrator also needs to copy the JDBC drivers from the database server to the application server machines.

How can the administrator meet these requirements?

ACreate a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.

BCreate a JDBC provider in the server scope and the data source in the node scope.Copy the driver to all application servers.Set the environment variable at the node level to the driver's path.

CCreate a JDBC provider in the node scope and the data source in the cell scope.Copy the driver to the deployment manager.Set the environment variable at the server level to point to the deployment manager path.

DCreate a JDBC provider in the application scope and the data source in the server scope.Copy the driver to all application server directories.Set the environment variable in each JVM to the driver's path.

Question: 3

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?

ACheck the System logs for OutOfMemoryErrors.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.

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

CConfigure Initial heap to be equal to the max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.

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

Question: 4

An EJB application posts a request message into a JMS destination and waits for a response message on a different JMS destination. To correlate the response message to the request message, the application uses the JMS correlationId of the message. The application waits up to five seconds for a response before timing out the request.

A Message Driven Bean (MDB) running on a different cluster is responsible for consuming the request message, process it and post a response message.

The destinations are defined in a Service Integration Bus (SIB) within the cell.

Intermittent timeout exceptions have occurred for the requester application. How can a system administrator correlate and analyze the debug information from both requester and consumer applications?

AEnable High Performance Extensible Logging (HPEL).Use HPEL logViewer command to see debug information.

BEnable a diagnostic trace in both requester and consumer servers.Use the Integrated Solutions Console (ISC) to set the admin=all trace.Analyze the trace.

CEnable High Performance Extensible Logging (HPEL).Enable Cross Component Trace (XCT) to include request IDs in log and trace records.Use HPEL logViewer command with appropriate filters to see debug information.

DUsing the Integrated Solutions Console (ISC), browse the request message that has timed out and look for any key application data.Search for exceptions using the key application data in both requester and consumer in native_stderr.log and native_stdout.log.

Question: 5

A system administrator was asked by the development team to inform them of any warning message which contains a string ''Connection'' on a WebSphere Application Server with High Performance Extensible Logging (HPEL) enabled.

AConfigure log detail levels to include filter on ''Connection'' string.

BUse the Log Viewer in the administrative console with filter on ''Connection'' string.

CUse the logviewer.sh or logviewer.bat command with appropriate options.

DUse the Log Viewer in the administrative console with filter on ''Connection'' string and enable the ''Refresh automatically'' feature.
