IBM 000-376 Exam : IBM WebSphere MQ V7.0, Solution Design

A bus company is implementing a solution which will display in real-time the arrival information of the next bus on the bus stop sign. Each bus is sending information about its position at regular intervals. What is the best way of implementing this solution given that there is limited bandwidth for communication? The bus stop sign:

• A. sends a message with a request every few minutes to a central system in order to query busposition. All replies are compressed.
• B. queries a central system for bus position using SOAP over HTTP
• C. subscribes to messages published by the bus
• D. replicates its own database every few minutes with a database stored on a central system

Which one of the following statements is true about the use of message properties and message selectors?

• A. Message selectors are specified in MQGET calls to filter out unwanted messages.
• B. Filtered out messages are discarded by the queue manager.
• C. MQMD fields but not MQRFH2 fields can be used in selectors like message properties forfiltering.
• D. Message selectors are specified in MQOPEN and MQSUB calls to filter out unwantedmessages.

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. 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.
• C. The ability to have another queue manager process messages in the event a primary queuemanager fails.
• D. Workload balancing to allow for multiple MQ Enabled applications to process messages in adual production lane configuration.

Business owners want to allow an existing application to be easily portable to any of four Linux servers in a cluster. For this, they want the four queue managers to be changed to have the same name. What must be the response of the WebSphere MQ Solution Designer?

• A. There is no problem.
• B. It is possible to define queue managers with identical names in a cluster, but it is notrecommended.
• C. It cannot be done. The repository will reject duplicate queue managers.
• D. Queue managers cannot be renamed, so this can only be done by recreating the queuemanagers. Beyond that, there is no problem.

WebSphere MQ clusters are sometimes positioned to provide high availability for backend services. For many use cases this works well; but which concern may make this solution unacceptable in some cases?

• A. Client applications connected to a queue manager cannot continue processing when itbecomes unavailable.
• B. Special considerations apply when software maintenance needs to be applied.
• C. Some topologies cannot be implemented because queue managers can only be members ofone cluster.
• D. In the event of a server outage messages already queued will be delayed until the server canbe restarted.
