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

1. The current depth of the SYSTEM.CLUSTER.TRANSMIT.QUEUE has not dropped below a certain number for several hours. Which of the following can be used to determine the channel(s) for which these messages are destined?

A) A DISPLAY QSTATUS command with the QMURID parameter.
B) A DISPLAY CHSTATUS command where XQMSGSA is greater than zero.
C) A DISPLAY CHSTATUS command where BATCHES is equal to zero.
D) A DISPLAY QSTATUS command for SYSTEM.CLUSTER.TRANSMIT.QUEUE with theUNCOM parameter.

2. Which of the following should generally be avoided if an application is being designed for optimal efficiency?

A) 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.
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) Make messages nonpersistent if they do not need to be recoverable.
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).

3. A new WebSphere MQ application with high volume requirements is being designed to run on Solaris. The solution designer is concerned about the performance of the application. The WebSphere MQ for Solaris V7 Performance Evaluation Report SupportPac provides all but one of the following types of information to the solution designer. Which is NOT discussed in this document?

A) Information that can be used to size the company new application Information that can be used to size the company? new application
B) Evaluation of the relative cost of one WebSphere MQ API vs. another in different scenarios
C) Suggestions for tuning WebSphere MQ
D) Evaluation of the relative cost of persistent messages vs. nonpersistent messages in different scenarios

4. 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 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.
B) WebSphere MQ clustering should be used to resolve queue names and locations dynamically.
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) 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.

5. When designing a WebSphere MQ based JMS application, it is most important that your application can capture which one of the following?

A) FFST information
B) MQException
C) JMSException
D) jmsTryCatch
