A system administrator is tasked with monitoring the overall health of the WebSphere environment to be able to tune the environment properly. Specifically, the administrator was asked to:

Which PMI modules can the administrator examine to obtain this data?

A. Number of requests, Java virtual memory, Average response time

B. Number of requests, Average response time, Web server thread pools

C. Average response time, Java virtual memory, Number of Live HTTP Sessions

D. Average response time, Web server thread pools, Number of Live HTTP Sessions

A system administrator has to design a new production environment to host a web application. The workload of this web application is expected to increase during special marketing campaigns.

Which one of the following topologies should the administrator configure to address the requirements for this new environment?

A. A Liberty collective environment with autonomic managers and on demand router (ODR).

B. A flexible management environment supported by one admin agent running in each node of the cell.

C. A dynamic cluster with autonomic managers, application placement controller and intelligent routers.

D. A heterogeneous cell with enough server to support the peak load spread across multiple nodes on the same machine.

A system administrator decides to use the advice from the Performance and Diagnostic Advisor to identify the optimum connection pool settings for data sources. In a cell, the data source db2datasource is defined under node scope and used by two servers from that node. The administrator receives two different sets of advice for db2datasource.

How should the administrator configure the data sources before reusing the Performance and Diagnostic Advisor?

A. Create a data source of the same name under cell scope.

B. Create a data source of the same name under server scope for each server.

C. Increase the minimum connection pool size for the data source.

D. Decrease the maximum connection pool size for the data source.

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 OutOfMemoryErrors.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.

The installation of WebSphere Application Server did not complete successfully, and a system administrator needs to troubleshoot the installation.

What can the administrator do to identify the cause of the installation failure?

A. Run the installver command with the appropriate command line options.

B. Check the files under the Agent data location of IBM Installation Manager.

C. Check the files under the logs directory of IBM Installation Manager installation directory.

D. Check the log.txt under .

A web application is hosted on an application server that receives HTTP requests from a third party application named myApp. The URIGroup mapping for this application is called default_host_myApp.

The development team asks a system administrator to configure the HTTP plug-in to prevent routing requests to any application server except server1.

The following exhibit shows the parts of the plugin-cfg.xml file that are relevant for myApp. The UriGroups for other applications are not shown in the exhibit.

What should the administrator do to the plugin-cfg.xml file to ensure that requests for default_host_myApp URIGroup are routed only to machine1?

A. Delete the Server tag for CloneId="b20000002"Delete all of the tags within the Server tag

B. Delete the UriGroup tag for default_host_myAppDelete all of the tags within the UriGroup tag

C. Delete the VirtualHostGroup tag for default_hostDelete all of the tags within the VirtualHostGroup tag

D. Edit the LoadBalanceWeight for server1 to 20Edit the LoadBalanceWeight for server2 to

A system administrator needs to create a cell for a test environment. The administrator uses the Profile Management Tool (PMT) to create the deployment manager profile using the advanced profile creation option and creates a custom profile using the typical profile creation option. The administrator examines the log files for the custom profile creation and sees an INSTCONFFAIL message indicating the deployment manager was not running during the custom profile creation.

How should the administrator fix this?

A. Delete the custom profile.Start the deployment manager.Create the custom profile again.

B. Start the deployment manager.Use PMT to re-create the custom profile.

C. Use the syncNode command to synchronize the node.

D. Run the addNode command to federate the custom profile.
