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

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

2. 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 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.
B) 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.
C) 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.
D) 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.

3. A solution designer is considering writing a base WebSphere MQ client application, and needs to ensure that after the message is taken off the queue, the message is not lost if the transaction fails. Which one of the following should be used?

A) Utilize the MQGMO_SYNCPOINT option to process within syncpoint
B) The Extended Transactional Client or the full MQ Server installation is required
C) Utilize the MQBEGIN and MQCMIT and MQBACK commands to process this in a Logical Unitof Work
D) Program with minimum application code to reduce the exposure window

4. A server application needs to record a unique id from the user who has created a request message in the Windows environment. Which MQMD field contains this information?

A) ApplOriginData
B) ApplIdentityData
C) UserIdentifier
D) AccountingToken

5. A publish/subscribe application is being designed. The requirements are that the published information should not be lost or expire. The subscriber application will connect periodically during the day to process the publications. Which publish/subscribe feature(s) are most appropriate for this type of application?

A) Retained publications
B) Nondurable subscriber
C) Durable subscriber
D) Nondurable subscriber with retained publications
