Question 1

What state must an application edition be in before it can be started?



Answer : B


Question 2

An administrator noticed that one of the servers in the core group is experiencing OutOfMemory. As a result, other servers in the core group failed to start.

What core group custom property should the administrator tune to prevent the affected server from impacting other servers in the core group?



Answer : A

IBM_CS_OOM_ACTION

Use this custom property to explicitly enable exception handlers that are specific for OutOfMemoryExceptions that occur when sending or receiving network messages. When this property is set to Isolate, if an OutOfMemoryException occurs when a network message is being sent or received, these exception handlers stop High Availability Manager communications to the Out of Memory process.

If IBM_CS_OOM_ACTION=Isolate is not added to the configuration settings for a core group, if a core group process runs out of memory, the Out of memory process might not be able to respond to all messages. This situation prevents multi-step protocols from completing, and prevents the starting server from receiving its initial view of the distributed state.


Question 3

Through what protocol can a Java client directly access EJBs running on an application server?



Answer : D

Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether or not the client is written in the Java programming language. The client doesn't even ''know'' what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients of web services. This flexibility enables you to integrate Java EE applications with web services.


Question 4

An administrator needs to resolve port conflicts after creating a managed node using the Profile Management Tool.

Which supported method can be used to resolve the port conflicts?



Answer : B

If you discover ports conflicts, then you can reassign ports manually. To reassign ports, run the updatePorts.ant file by using the ws_ant script.


Question 5

Which of the following gives clues when comparing traces from different processes and correlating events of different servers in the same data center?



Answer : B

Reading a Trace File


Question 6

An administrator notices a sudden increase in the user load that causes resource contention on the database server.

What preventive measure can the administrator take to avoid database outage?



Answer : C

Maximum Connection Pool Size

When determining the maximum size of the database connection pool, consider the following issues:

The total number of connections that the WebSphere Commerce cluster can open to the database should not overwhelm your database.


Question 7

What are two automated administrative tasks that can be done with configuration checkpoints? (Choose two.)



Answer : A, D

If you want to preserve delta checkpoints, you must archive checkpoints before they are automatically deleted.

A delta checkpoint is created automatically by the product each time a configuration change is made.
