An application is required to retrieve rows from a relational database table and send them across WebSphere MQ to a remote queue manager, where a receiving application consumes them.
After a successful MQPUT of a message, the corresponding row is to be deleted from the database. It is intended to run this application using the free WebSphere MQ Client. The delivery of each message is to be guaranteed. Which of the following is true about this implementation?

• A. This solution can be implemented using the free WebSphere MQ Client, provided that the receiving application can recognize and handle repeated delivery of the same message.
• B. This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client.
• C. It cannot be done using the free WebSphere MQ Client; the Extended Transactional Client is required, since two phase commits are needed for this solution.
• D. It cannot be done using the free WebSphere MQ Client; a local queue manager is required to support the guaranteed delivery of the messages.

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. 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).
• 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. 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).

A company needs to send state information to many recipients. The recipients will change over time, and they only want to receive the latest data if and when they need it. Which of the following most closely satisfies the requirements and is most efficient for the subscriber?

• A. Nondurable subscriptions
• B. Distribution lists
• C. Durable subscriptions
• D. Retained publications and use of MQSUBRQ

A solution designer is looking to utilize industry standard technologies but does not want to settle for the qualities of service that HTTP offers. Which of the following is not a benefit of using SOAP/WebSphere MQ over SOAP/HTTP?

• A. Ability to provide access to legacy applications
• B. Assured delivery
• C. Integration with, and reuse of, existing WebSphere MQ infrastructure
• D. WebSphere MQ clustering for load balancing and enhanced reliability and availability

The solution designer is considering how a WebSphere MQ application program can be made aware of problems when a message it created is delivered by a remote channel agent. Which of the following could be used for this purpose?

• A. A GUI utility to display the dead letter queue on the remote queue manager, so that the dead letter header can be browsed.
• B. There is no way to determine the success of a put by a remote message channel agent from within the local application program.
• C. A report message option can be set by the sending application program
• D. The Completion and Reason code in the sending application program
