You are using the WebLogic Diagnostic Framework (WLDF) to monitor your domain for certain scenarios based on runtime data of your running servers. Different groups are responsible for different aspects of the application.

As a result, your configuration must fulfill the following requirements:

    Notifications must be sent only to the correct group that is responsible for the respective part of the application.

    You must ensure that you can enable and disable monitoring for each level whenever it is needed.

How would you configure WLDF watches and notifications to achieve this result? (Choose the best answer.)

A.

Configure a single module with a watch for each area, and use a notification filter to send an email to the correct group for each area.

B.

Configure a module for each area with a watch that triggers a notification email for the group responsible for that area.

C.

Configure a single module with a watch for each area, and each watch triggers a notification email for the group responsible for that area.

D.

Configure a module for each area with a watch that uses a notification filter to send an email to the correct group for each area.

Your clients are connected to distributed destinations to consume messages sent to various JMS topics.

Recently, JMS connections got interrupted due to a network failure and your clients dropped their connections as well.

How would you ensure seamless failover for your clients when a distributed destination fails? (Choose the best answer.)

A.

No action should be needed at the client’s level if the failover is being handled properly at the cluster level.

B.

Set the с1ientReconnectOptions parameter to Automatic in the Administration Console under the destination configuration general page.

C.

Implement an automatic reconnect mechanism in the client exception handler.

D.

Set AutomaticClientReconnect to Enabled in the Administration Console under the destination configuration general page.

What value should you set for the JMSExpiration header? (Choose the best answer.)

A.

B.

999

C.

1

You are concerned with messages being received systematically. You designed Message-Driven beans (MDB) to guarantee the most reliable way to consume messages.

In which three scenarios would JMS always redeliver a message? (Choose three.)

A.

when the onMessaqe() method of the MDB throws a Java error

B.

when the transaction the MDB participates in eventually fails and rolls back

C.

when the onMessage() method fails to acknowledge the reception of the message

D.

when messages are not being sent as part of a transaction

E.

when messages are non-persistent

You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.

Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)

A.

AUTO_ACKNOWLEDGE

B.

CLIENT_ACKNOWLEDGE

C.

DUPS_OK_ACKNOWLEDGE

D.

DEFAULT_ACKNOWLEDGE

Your application includes a message driven bean (MDB) that is listening to messages on a JMS Queue. You need to ensure that every message is processed exactly once by the MDB.

Which configuration allows you to achieve this requirement? (Choose the best answer.)

A.

Add an exception handler for the onMessage method in the MDB.

B.

Set the Redelivery Limit for the Queue to zero.

C.

Use container-managed transactions, so that messages are redelivered if unacknowledged.

D.

Set the MDB instance count to 1 in the deployment descriptor.

You are reviewing the scheduled maintenance of your domain after adding a new cluster.

Which statement is true when configuring a migratable target within a WebLogic Server cluster? (Choose the best answer.)

A.

Allow Post-Migration Script To Run On a Different Machine is selected by default.

B.

The default server migration policy is Auto-Migrate Exactly-once Services.

C.

The participating cluster should include at least one configured server.

D.

An automatically migrated service will always be hosted on the specified User Preferred Server.

Which two statements correctly describe the WLST nmGenBootStartupProps command? (Choose two.)

A.

The target root directory must be on the same machine on which Node Manager is running.

B.

The target root directory must be on the same machine on which the Administration Server is running.

C.

The name of a server must be supplied to the nmGenBootStartupProps command; otherwise, the command will fail.

D.

If you do not specify a server name using the servername argument, the argument defaults to myServer, which must match a server name in the domain or the command will fail.

E.

The nmGenBootStartupProps command generates the Node Manager properties files, boot.properties and startup.properties, for the specified server.

I am sending a set of ten JMS messages. I want all of these messages to be sent successfully or none at all.
