Questions # 11:

A system administrator has added a server cluster as a member of a service integration bus (SIB). The administrator needs to configure one messaging engine for each server in this cluster and to have a failover location for each messaging engine.

What should the administrator do to achieve the required design?

Options:

Configure a new messaging engine in each server to support failover.

Configure the data store for each messaging engine for each server in the cluster.

Select scalability with high availability as the messaging engine policy.

Create a core group policy to restrict each messaging engine to a particular server.

Questions # 12:

A system administrator needs to install WebSphere Application Server using response files, so that a silent install can be done. The administrator has ensured that all required prerequisites have already been installed and, has downloaded and expanded the required WebSphere Application Server installation files.

What can the administrator run to install the product?

Options:

install –options responsefile.xml -silent

install –acceptLicense –options responsefile.xml -silent

imcl –acceptLicense input responsefile.xml –log logfile.txt

IBMIM –acceptLicense –input responsefile.xml –log logfile.txt

Questions # 13:

A system administrator runs a Jython script that creates and configures several servers and realize that the script fails before completing. Although many tasks succeeded, they are rolled back when the script fails.

Before running the script again, what can the administrator add to the script after each task so the completed tasks are committed even if other tasks fail?

Options:

AdminApp.update()

AdminConfig.save()

AdminControl.invoke(server, ‘sync’)

AdminTask.backupJobManager(‘server’)

Questions # 14:

A system administrator needs to trigger a javacore only when a java,net.SocketTimeoutException is encountered in real time.

What does the administrator have to configure to trigger the javacore dump?

Options:

Configure the JAVA_DUMP_OPTS environment variable to capture javacore for ANYSIGNAL and all exceptions.

Configure an –Xdump:java Generic JVM argument on WebSphere Application Server with the filter for java.net.SocketTimeoutException.

Code wsadmin script to capture javacore and then execute it after the java.net.SocketTimeoutException has been encountered.

Use the log filter in HPEL to monitor for java.net.SocketTimeoutException and then gather a javacore dump from the Integrated Solutions Console (ISC).

Questions # 15:

The application placement controller has been configured with elasticity mode enabled. Intermittently, all instances of a dynamic cluster are removed. After further review, the system administrator noticed that it occurs during peak load on another dynamic cluster.

The administrator wants to keep at least one instance available. Which configuration is needed in the dynamic clusters?

Options:

Enable application lazy start with elasticity mode.

Set the proactiveIdleStop custom property to true.

Set the Number of instances to a value greater than zero.

Disable the option “If other dynamic clusters need resources, stop all instances of this cluster during periods of inactivity”.

Questions # 16:

A developer created an enterprise application which contained data source and security role information. The developer asked a system administrator to install this application to an application server where global security is enabled using the Integrated Solutions Console (ISC). A new data source was configured at the server scope for the use of this application. While load testing the application, the developer noticed that the attributes configured on the new data source were ignored by the application server.

How can the administrator ensure that the attributes configured on the new data source are used by the application server?

Options:

Create the data source under cell scope instead of server scope.

Delete any data source of the same name defined under node, cluster or cell scope.

Reinstall the application and clear the Process embedded configuration check box.

Correct the component-managed and container-managed authentication aliases set on the data source.

Questions # 17:

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

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

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

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

Questions # 18:

A system administrator discovers an issue that requires a change to a federated server. In this cell, WebSphere administrative security is enabled, but application security is not enabled.

How should the administrator make this change?

The administrator should use:

Options:

a web browser to connect to the node agent https port.

a web browser to connect to the deployment manager admin_host port.

the job manager to submit a job to update the unmanaged server.

an ssh connection to the node and modify the client_types.xml file.

Questions # 19:

A system administrator has configured a network deployment cell containing multiple nodes and global security enabled with an LDAP repository. To increase capacity, the administrator needs to add additional nodes to the cell. After adding the nodes by using both scripts and the Integrated Solutions Console (ISC), the administrator examines the System.out log for the deployment manager and notices the following message:

Question # 19

How can the administrator resolve this problem?

Options:

Disable Java 2 security.

Restart the deployment manager.

Increase the RSA token timeout value.

Change the number of active LTPA keys.

Questions # 20:

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?
