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.
Answer: D

2. An organization will use WebSphere MQ to connect its central z/OS systems to its 20 branch offices. Each of the 20 offices runs applications on an AIX platform. The z/OS system supports two z/OS LPARs. One is for production and the other is for both development and testing. Separate AIX machines are available for production and testing and development. There will be individual queue managers supporting production, testing and development. Which of the following naming standards is MOST appropriate?
A. Channel names will be <sending-qmgr-name>.to.<receiving-qmgr-name>.
B. z/OS queue manager names will be MQQx where x= P, T, or D for the Production, Testing, and Development environments.
C. AIX queue manager names will be AMQx where x= P, T, or D for the Production, Testing, and Development environments.
D. Applications will query a z/OS DB2 table for the name of the correct queue manager to use.
Answer: A

3. Which of the following message standards is MOST appropriate for an enterprise that needs to tag each application message with a 48 byte identifier?
A. Use the CorrelId field in the MQMD.
B. Use the ReplyToQ field from the MQMD.
C. Use the CorrelId field in the transmission queue header (MQXQH).
D. Use a customer specified message header to precede application data.
Answer: D

4. A large enterprise has an MQ-based messaging infrastructure to support a diverse range of applications across multiple platforms. A number of the applications are JAVA based. Some execute in an iSeries environment. The enterprise must now begin to exchange messages with its business partners using WebSphere MQ.

Answer: A

5. An application publishes documents in PDF format as WebSphere MQ RFH2 messages to a wide range of recipient platforms. Which of the following is critical to ensure the documents are processed correctly?
A. The National Language support on the recipient systems must match the code page with which the PDF document was created.
B. The message format in the MQMD must be specified as MQFMT_NONE.
C. The PDF document size must not exceed 4MB.
D. This is only supported on Windows platforms.
Answer: B

6. A company has a production WebSphere MQ cluster. They have recently upgraded to the latest version of WebSphere MQ. The current cluster has three queue managers, two in Paris which contain an instance of APP.QUEUE application queue. The third in London acts as a gateway to facilitate work load balancing. There is a requirement to add two queue managers in Rome to the network to take 25% of the workload. Which of the following should be performed to accomplish this task?
A. Add the Rome queue managers to the existing cluster. Set CLWLWGHT values on the channels.
B. Add the Rome queue managers to the existing cluster. Set CLWLPRTY values on the queues.
C. Add the Rome queue managers to the existing cluster. Set CLWLUSEQ values on the queue managers.
D. Update the Cluster Workload Exit accordingly.
Answer: A

7. A company’s inventory application operates using a WebSphere MQ cluster containing several instances of the queue, STOCKQ. Assume one instance of STOCKQ is local to queue manager QM1 and CLWLUSEQ remains at its default value. Which method will be used by the standard workload management algorithm on QM1 to determine which queue manager is to receive a message MQPUT to STOCKQ?
A. It will always select the local queue manager.
B. It will select the queue manager that it sent to most recently.
C. It will select the queue manager that is receiving the least number of messages.
D. It will choose from the available queue managers using a round-robin approach.
Answer: A

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
