IBM WebSphere MQ V7.0, Solution Design Sample Questions:

1. An application queue is triggered for trigger type of DEPTH. Following this, what action should the job or program that was started as a result of the trigger take before it ends, so that the queue will be triggered again the next time that trigger depth (TRIGDPTH) is reached?

A) It needs to use MQSET or an ALTER QLOCAL command to reset triggering (TRIGGER) for the queue.
B) It needs to reset trigger depth (TRIGDPTH) for the queue through an MQSET or ALTER QLOCAL command.
C) No action needs to be taken. The queue manager will create the next trigger message when the current depth of the queue once again reaches trigger depth (TRIGDPTH).
D) It needs to reset trigger depth (TRIGDPTH) and triggering (TRIGGER) for the queue, using MQSET or an ALTER QLOCAL command.

2. A Windows application using the WebSphere MQ client to connect to a Linux queue manager on a pSeries server receives messages originating from an iSeries system. The message data appears incomprehensible. Select the most likely explanation for this.

A) A message conversion exit was not provided.
B) Message conversion was requested both on the sending channel agent and in the receivingapplication MQGET request, resulting in doubleMessage conversion was requested both onthe sending channel agent and in the receiving application? MQGET request, resulting indouble conversion.
C) No message conversion was requested in the receiving application MQGET request nor on thesending channel agent.No message conversion was requested in the receiving applicationMQGETrequest nor on the sending channel agent.
D) Message conversion failed because an incorrect CCSID was specified in a MQCCSIDenvironment variable on the Windows system.

3. A solution designer and the development team are discussing whether the "Read Ahead" feature of WebSphere MQ can improve performance for the application they are developing. Which of the following would be MOST able to benefit from this feature?

A) Persistent or nonpersistent messages consumed by a client program
B) Nonpersistent messages consumed by a client or a bindings program
C) Persistent or nonpersistent messages consumed by a client or a bindings program
D) Nonpersistent messages consumed by a client program.

4. A new publish/subscribe application needs to be implemented. A mix of JMS and non-JMS WebSphere MQ applications will need to cooperate. It is suggested that the solution should be implemented using WebSphere MQ V7.0 rather than V6, because of the new publish/subscribe implementation of ebSphere MQ V7.0. Which of the following is NOT a benefit of the new publish/subscribe implementation in WebSphere MQ V7.0 over previous versions?

A) Topics are native WebSphere MQ objects, just like queues; new MQI calls and options areprovided to give applications a more intuitive way to access these than the use of RFH2headers.
B) Durable subscriptions are now supported.
C) A hierarchical system of topic based security is available and can be administered usingWebSphere MQ Explorer and setmqaut commands.
D) Message selectors and message properties can be used to further qualify subscriptions and thus reduce the number of messages received.

5. A customer has an environment where applications are frequently redeployed to different servers
to react to changing capacity needs. Which of the following will provide the best support for the affected applications to be moved?

A) Affected applications will be linked with the MQ Client interface and will maintain connectionsto all affected queue managers simultaneously; they will then find the respective queues byquerying the queue managers.
B) Affected applications will read configuration files from their local file system that are updatedby administrators to reflect the new locations of destination queues; they then have todynamically build the appropriate queue names before opening the queues.
C) Affected applications will connect to default queue managers and use generic, locationindependent queue names only; a set of alias and remote queue definitions are used in thequeue managers to connect applications to where the real queues are at any point in time.Input queues need to move with the owning applications.
D) Affected applications will first connect to a central queue manager via the WMQ client interfacewhere they can find configuration information in a special queue; they then open theirrespective application queues accordingly.
