1.A large enterprise, running on a group of z/OS machines, wishes to create an audit trail of changes made to the definitions of WebSphere MQ objects on its queue managers, including the ID of the person making the change and the date and time the change was made. Which of the following methods is MOST appropriate for gathering the necessary data?

A: Run the SAVEQMGR program and combine the various reports into a single file.

B: Write a PCF program that issues RESET QUEUE STATISTICS commands and run it on each queue manager, sending the results to a central queue. C: Enable CONFIGEV and redefine SYSTEM.ADMIN.CONFIG.EVENT as a remote queue on each queue manager, pointing to a single local event queue. D: Create a text file of MQSC DISPLAY commands and run it on each queue manager, sending the results to a single queue. Correct Answers: C

2.The use of WebSphere MQ clustering is being explained as part of a solution. Which two of the following are benefits of WebSphere MQ clustering? A:Vertical scaling B:Workload balancing C:Reduced network latency D:Reduced channel definitions E:Reduced local queue definitions

Correct Answers: B, D

3.A customer has computer centers in eight European cities which will be connected by WebSphere MQ. Which of the following is an advantage of any-to-any WebSphere MQ topology versus a hub and spoke topology in this environment? A: Reduced conversion required B: Reduced message delivery delay

C: Higher probability of persistent message delivery D: Improved channel performance Correct Answers: B

4.A financial organization is implementing WebSphere MQ to connect applications in a z/OS batch environment. A security requirement exists to only allow some applications to put messages on a particular queue. Also, the security requirement allows some other applications to only get messages from that queue. How should this security requirement be implemented? A: Define separate PUT and GET queues. B: Design the application to use a model queue.

C: Utilize separate alias queues for PUT and GET operations.

D: List the authorized applications as PUT/GET with ENABLED/DISABLED parameters.

Correct Answers: C

5.A company has a central database that receives nightly updates from several remote servers on a variety of platforms. These updates are received via FTP a

nd then processed by a batch program. It has been determined that the updates need to be processed as they occur and that a messaging based solution will be used. Which two of the following aspects of the messaging solution are MOST important to consider? A:Platform coverage

B:Publish/Subscribe capability C:Transactional capability D:Security capability

E:Maximum size of the message Correct Answers: A, C

6.The WebSphere MQ client interface is popular in part because the client software is free, but this is offset by a number of functional limitations. When deciding whether to deploy an application with the client interface or with a local queue manager, these must be considered. Which of the following is NOT a limitation of the WebSphere MQ client?

A: Clients cannot be centrally managed by WebSphere MQ tooling.

B: In the event of a network outage it can be difficult to determine if the last API call was actually performed.

C: Data cannot be stored as messages by the client in the event of network outages.

D: Transactional processing with local units of work is not supported. Correct Answers: D

7.What requirement must be met before an application is permitted to specify the MQMD Identity Context fields?

A: The application must be specifically authorized. B: The queue manager must be specifically authorized. C: MQPMO_PASS_IDENTITY_CONTEXT must be specified.

D: The UserID running the application must be specifically authorized. Correct Answers: D

8.An architect has designed an AIX application that will update WebSphere MQ queues and a DB2 database within a single unit of work, using WebSphere MQ as the transaction manager. The architect wishes to be sure that all possible recovery options are covered within the application in the case of a failure of the transaction manager or the resource managers. In which of the following circumstances should the architect consider preparation of additional recovery procedures? A: If the application crashes within the unit of work before the MQCMIT B: If the database crashes within the unit of work before the MQCMIT C: If the database crashes during the MQCMIT, before the database indicates that it is prepared to commit

D: After the database indicates that it is prepared to commit, and the transaction manager can not be recovered Correct Answers: D

9.An existing high volume WebSphere MQ for z/OS V6 application is changing data stored in messages from a COBOL Copybook format to XML format. There will be a delay before messages can be transmitted. The requirements specify tha

t with move to XML, over 4GB of message data may now need to be held at one time. What action should be recommended?

A: These volumes are unacceptable to WebSphere MQ. Redesign the application.

B: The underlying page set should be resized to account for the new volumes. C: A message exit should be written to compress data stored in the queues D: Transmission queue maximum queue depth should be increased. Correct Answers: B

10.Given a scalable interactive application which uses non-persistent messages, which of the following is MOST appropriate for the reply queues? A: A model queue

B: A permanent dynamic queue C: A temporary dynamic queue D: A predefined local queue Correct Answers: C
