If a series of exceptions is thrown for a WebSphere MQ JMS program, which of the following is typical?

• A. The order in which the exception messages are shown is random and cannot be relied on.
• B. The exceptions at the top of the list will be more general, and subsequent exceptions willprovide more detail about the cause of the problem.
• C. The WebSphere MQ Reason and Completion code will not be reported in the exceptions.
• D. The most detail about the cause of the problem should be found in the exception at the top ofthe list.

There is a requirement for a failover mechanism as part of an application to be deployed on Sun servers. The organization has standardized on Veritas Cluster Server to manage failover on the machines. What should be considered when designing the solution?

• A. Implement shared queues for true high-availability.
• B. Utilize WebSphere MQ clustering to send the traffic to the failover server.
• C. State data needed by the application for recovery after a failure needs to be on shared disks.
• D. The application needs to be designed to handle concurrent database transactions from each ofthe Veritas nodes.

Which of the following should generally be avoided if an application is being designed for optimal efficiency?

• A. Make messages nonpersistent if they do not need to be recoverable.
• B. Bundle the data to be transmitted into as few messages as possible (e.g., rather than sending a hundred 1MB messages, send one 100MB message).
• C. Code programs to open and close queues, or connect and disconnect from the queue manager only once, if the queues or connection will be used again.
• D. Group a batch of messages within a unit of work where appropriate, so that they can be committed all at once (e.g., get and put messages under syncpoint and commit them in groups of 10, rather than committing them individually).

An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that the delivery of certain persistent mission critical datagram messages needs to be recorded in a central location. The delivery information must not be lost. The mechanism used must not be dependent on cooperation of the receiving applications. Which of the following designs will meet these requirements?

• A. The sending application will put a copy of each message on a central queue reserved for thispurpose, including the completion code and reason code of the original request.
• B. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the resulting report messages will be delivered to the SYSTEM.ADMIN.REPORT.QUEUE onthe receiving queue manager.
• C. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the Reply-to queue fields point at a queue on a central queue manager reserved for thispurpose.
• D. In the MQMD of the messages in question, PAN, NAN and EXCEPTION reports will berequested; the Reply-to queue fields point at a queue on a central queue manager reservedfor this purpose.

A solution designer is considering different API options for a new WebSphere MQ application.
Only IBM supported WebSphere MQ programming options should be considered. Which one of the following is not supported by IBM?

• A. XMS
• B. Perl
• C. WebSphere MQ classes for .NET
• D. JMS
