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

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

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

2. An application is required to retrieve rows from a relational database table and send them across WebSphere MQ to a remote queue manager, where a receiving application consumes them.
After a successful MQPUT of a message, the corresponding row is to be deleted from the database. It is intended to run this application using the free WebSphere MQ Client. The delivery of each message is to be guaranteed. Which of the following is true about this implementation?

A) It cannot be done using the free WebSphere MQ Client; the Extended Transactional Client is required, since two phase commits are needed for this solution.
B) It cannot be done using the free WebSphere MQ Client; a local queue manager is required to support the guaranteed delivery of the messages.
C) This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client.
D) This solution can be implemented using the free WebSphere MQ Client, provided that the receiving application can recognize and handle repeated delivery of the same message.

3. A company needs to improve availability of client connections for its distributed applications.
Which one of the following is a true statement about a new option or capability of WebSphere MQ
V7.0 that could improve availability?

A) There is a new maximum instance channel limit that can catch a client application instancethat is attempting to use an excessive number of channel connections
B) TCP/IP client connections are now always full duplex, and full duplex can support earlierdetection of network failures
C) Client connections on the same server can share an instance of a channel connection,reducing the number of sockets required
D) The new MQSTAT verb can be used to determine the health of a Queue Manager, leading toquicker detection and recovery from an outage

4. The use of Shared Queues on z/OS provides which of the following high availability benefits that
are not available on distributed platforms?

A) The ability to have another queue manager process messages in the event a primary queuemanager fails.
B) In the event of a queue manager failure, the ability of one of its peers to provide uninterruptedservice to the queues that the failed queue manager had been processing.
C) Workload balancing to allow for multiple MQ Enabled applications to process messages in adual production lane configuration.
D) A platform-based failover capability to provide access to queue data for processing.

5. 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) written to a file on the local file system and transmitted to the central audit trail server via reliable file transfer over WebSphere MQ.
B) 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.
C) inserted into a central database table via a remote access database client under control of the local WebSphere MQ transaction.
D) sent as a persistent WebSphere MQ message and forwarded to the queue manager of the central server asynchronously.
