IBM WebSphere MQ V7.0, System Administration Sample Questions:

1. An IBM WebSphere MQ client application puts messages onto remote queue RQ on queue manager QM1, which resolves to the local queue LQ on queue manager QM2. A new version of the application has been deployed that has the capability to put messages greater than 4MB. The administrator changed the max message length attributes for the queue managers, transmission queue, sender-receiver channels and LQ to handle the larger messages. The administrator was later notified that messages greater than 4MB are still not reaching LQ. The most likely cause of the problem is the max message length attribute:

A) of the server connection channel was not changed
B) was not set on the environment variable MQSERVER
C) in file qm.ini was not changed
D) of RQ was not changed

2. Which of the following statements about persistent messages is correct?
Persistent messages:

A) cannot be stored in the same queue with nonpersistent messages
B) are always written to a log
C) should always be used no matter the data is critical or not.
D) can survive a queue manager restart but not a system failure

3. Which of the following statements are true, regarding applications that communicate via IBM WebSphere MQ? IBM WebSphere MQ applications have to agree upon:

A) the layout of the message data exchanged
B) the maximum number of messages sent within a given time period
C) the network protocol used
D) the name(s) of the queue(s) used
E) the platforms they are running on

4. QM2 and its objects have been recreated using the save queue manager definitions. The sender channel on queue manager QM1 is in retry status with an error message AMQ9526: Message sequence number error for channel 'QM1.TO.QM2'. Which action will recover the channel?

A) Reset the channel
B) Recreate the objects using save queue manger definitions
C) Restart the receiver channel
D) Restart the sender channel

5. An application using several queue managers is being tested for its end-to-end message throughput rates. The delivery times for the messages are longer than what the developers expect, and some messages are randomly lost. What can be done to help resolve this problem?

A) Monitor the DEFAULT.SYSTEM.MSG.ROUTE queue for message routing events
B) Record and evaluate activity information recorded by a trace-route message
C) Use a third party software package since IBM WebSphere MQ does not provide the ability totrack messages
D) Evaluate the event messages that arrive on the dead letter queue
