Options:

A.

AdminApp.update()

B.

AdminConfig.save()

C.

AdminControl.invoke(server, ‘sync’)

D.

AdminTask.backupJobManager(‘server’)

Question 2

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?

Options:

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.

Question 3

After installing an enhanced EAR in a WebSphere Application Server environment, a system administrator with Configurator privileges is able to see a JDBC provider and a data source in the Integrated Solution Console (ISC) but is not able to delete these resources.

How can the administrator resolve this issue?

Options:

A.

Use the AdminTask object to delete the resources.

B.

Stop all application server instances and then delete the resources.

C.

Ask another administrator with iscadmin privilege to delete the resource.

D.

Edit the EAR to remove the application scoped resources and reinstall the application.

Question 4

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?

Options:

B.

C.

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

D.

Check the log.txt under .

Question 5

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?

Options:

A.

Configure the storm drain health policy.

B.

Configure the on demand router (ODR) transport chain to tune inbound connections.

C.

Monitor the JVM heap usage to determine a new server weight.

D.

Enable the PMI Extended statistic set and use the Connection Pool summary report.

Question 6

What can the system administrator configure to ensure users can continue to work if one of the cluster server fails?

Options:

A.

An increased session timeout.

B.

A cluster of external HTTP servers.

C.

A load balancer to spread work between existing servers.

D.

A WebSphere eXtreme Scale HTTP session management.

Question 7

A system administrator needs to set a new Liberty profile environment to support an application.

What should the administrator do to enable this environment for high availability and scalability of the application?

B.

Define multiple servers in a cluster in one collective controller.

C.

Define multiple collective controllers within a Liberty collective.

D.

Define multiple server members in multiple collective controllers.
