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

When designing test scenarios for pre-production testing, it is good practice to closely match the production environment in its metrics in order to produce realistic runtime behavior. In this context, which of the following statements about WebSphere MQ logging capability BEST describes the role that logging considerationsIn this context, which of the following statements about WebSphere MQ' logging capability BEST describes the role that logging considerations play in quality assurance or user acceptance testing?

• A. Even with identical logging parameters it is difficult to simulate the exact load on the loggingsystem, since the actual requirements are accumulated across all concurrently runningapplications, including channels.
• B. Since changing the log file sizes requires a rebuild of the queue manager it is recommended tocreate the QA queue managers with as large a log space allocation as possible.
• C. It is important to run with exactly the same logging style and log file sizes as in production inorder to properly test the application behaviorIt is important to run with exactly the samelogging style and log file sizes as in production in order to properly test the application'sBehavior regarding the use of log space.
• D. As long as the same logging method (circular or linear) is used as in the productionenvironment, there will be no problems; the logging algorithms can handle unexpected loadsgracefully.

An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that certain mission critical applications record audit trail data which is to be collected in a central location. No information can be lost. A central data warehouse must be loaded daily with this information as soon as possible after end of business. Which of the following proposed solutions is best in terms of the requirement, reliability and overall performance? The audit trail data is:

• A. sent as a persistent WebSphere MQ message and forwarded to the queue manager of the central server asynchronously.
• B. inserted into a central database table via a remote access database client under control of the local WebSphere MQ transaction.
• C. written to a file on the local file system and transmitted to the central audit trail server via reliable file transfer over WebSphere MQ.
• D. inserted into a local database table under two phase commit using WebSphere MQ as the transaction manager and a bulk update is performed at end of day.

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

Why should only privileged users be permitted to define alias queues?

• A. A QALIAS can name another alias queue as its TARGET, which can potentially create aninfinite loop.
• B. There is no check if the TARGET is defined or not.
• C. An alias queue could have a remote queue for its TARGET.
• D. Users can bypass access control by creating a QALIAS.
