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

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

2. An application is being designed which will send updates about customers to different applications. Given the sensitive nature of the data, the sending application needs to manage which applications receive the datA. Which of the following is the best solution to ensure this?

A) All receiving applications should listen on the same queue and the sending application shouldsend separate copies of the message with attributes which allow the receiving applications tosearch the queue for their own copies.
B) Each application should have its own queue on which it will listen for updates
C) All applications should listen on the same queue and after processing the message shouldupdate its header so the last application process can remove it from the queue
D) Apply the publish-subscribe paradigm (one-to-many).

3. 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 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.
B) 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.
C) 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.
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.

4. There is a requirement for a failover mechanism as part of an application to be deployed on Sun servers. The organization has standardized on Veritas Cluster Server to manage failover on the machines. What should be considered when designing the solution?

A) State data needed by the application for recovery after a failure needs to be on shared disks.
B) Implement shared queues for true high-availability.
C) Utilize WebSphere MQ clustering to send the traffic to the failover server.
D) The application needs to be designed to handle concurrent database transactions from each ofthe Veritas nodes.

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