The use of Shared Queues on z/OS provides which of the following high availability benefits that
are not available on distributed platforms?

• A. A platform-based failover capability to provide access to queue data for processing.
• B. The ability to have another queue manager process messages in the event a primary queuemanager fails.
• C. In the event of a queue manager failure, the ability of one of its peers to provide uninterruptedservice to the queues that the failed queue manager had been processing.
• D. Workload balancing to allow for multiple MQ Enabled applications to process messages in adual production lane configuration.

A solution developer needs to promote newly developed applications from the development environment through the user acceptance test environment and into the production environment. Which of the following will best avoid issues with naming conventions for application-owned permanent queues?

• A. The names should be identical across the various environments, so that no changes to applications or object definitions between queue managers are required during promotion.
• B. The alias queue names used in the application code will be prefixed with EV? AT?or RD? respectively, so that applications can beThe alias queue names used in the application code will be prefixed with ?EV? ?AT?or ?RD? respectively, so that applications can be promoted between environments without having to change the queue names.
• C. A standard should be implemented by which all queue names will be prefixed with the queue manager name, which will begin with the strings EV? AT?or RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before?EV? ?AT?or ?RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before opening the queues.
• D. WebSphere MQ clustering should be used to resolve queue names and locations dynamically.

An application creates documents in PDF format, which are subsequently transmitted via WebSphere MQ to a number of other servers in the network. Each server runs its own queue manager. The documents received by some servers are consistently corrupted, whereas on other servers the documents are intact. Other message traffic seems unaffected. What is the most likely source of this problem?

• A. The affected servers run different CCSIDs from the servers creating the documents and the message descriptor specifies MQMFormat as QSTR? causing message conversion.?QSTR? causing message conversion.
• B. Incompatible message compression parameters are configured on the sending and receiving channel agents.
• C. The network connection to the affected servers is unreliable and a message retry exit was not specified on the sending channel agent.
• D. The environment variable MQCCSID specifies an incorrect value on the affected servers.

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).

An application receives messages created on Windows workstations and, after doing transformations, forwards them to a target system running on z/OS. There is a requirement for passing the original username, but information about the date and time associated with the message should be set by the forwarding application. What is the best way of doing this?

• A. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application
• B. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in forwarding application
• C. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in the forwarding application
• D. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application
