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

1. A solution designer is using the DEFPSIST attribute on the queue definition to determine message persistence. Queue Manager QMA has a QREMOTE queue defined that points to a QALIAS definition on Queue Manager QMB, which in turn names a QLOCAL queue as its TARGET. If an application puts a message to the QREMOTE on Queue Manager QMA, which of the queue definitions will control the persistence of the message?

A) The QLOCAL on QMB
B) All four of the queue definitions (QREMOTE, Transmission queue, QALIAS, QLOCAL)
C) The transmission queue on QMA
D) The QREMOTE on QMA

2. Business owners want to allow an existing application to be easily portable to any of four Linux servers in their data center. For this they want the four queue managers on these servers to be changed to have the same name. What must be the response of the WebSphere MQ Solution Designer?

A) It cannot be done. All interconnected queue managers must have unique names.
B) Queue managers cannot be renamed, so this can only be done by recreating the queue managers. Beyond that, there is no problem.
C) There is no problem.
D) It is possible to define queue managers with identical names in a network, but it is not recommended.

3. While trying to get messages from its input queue a program is receiving notification that no messages are available. However, the queue depth indicates that there are messages on the queue. Which of the following are possible explanations for this?

A) The program is failing to specify a MsgId or CorrelId, so no messages are being are beingreturned when it issues an MQGET.
B) The queue has been set to et inhibitedby an administrator.The queue has been set toyetInhibitedby an administrator.
C) Messages have been put to the queue by another program, but have not been committed yet.
D) The program lost the authority to get messages from this queue as a result of an administratoraction.
E) The program is specifying a particular MsgId or CorrelId that does not match any messagescurrently on the queue.

4. A bus company is implementing a solution which will display in real-time all bus positions on a central dashboard. Each bus is transmitting position information at regular intervals. What is the best way of implementing this solution given that there is limited bandwidth for communication?

A) Each bus sends messages to a separate queue and the dashboard application checks thosequeues every few minutes.
B) Each bus sends a message to a central queue which is read by the dashboard application
C) Each bus updates a message in a common queue and the dashboard application reads thewhole queue every few minutes.
D) Each bus updates a message in a central queue using its number as a key and the dashboardapplication reads the whole queue every few minutes.

5. A solution designer is looking to implement a highly available WebSphere MQ solution. In the event of a queue manager failure, there is a requirement for several backup queue managers to get and process the messages from the primary input queue that was being processed by the failed queue manager. Considering the advances in high availability options (e.g. HACMP, WebSphere MQ clustering), which of the following deployment options is most valid?

A) z/OS, AIX, Windows
B) z/OS, AIX, Windows, Red Hat Enterprise Linux
C) z/OS
D) z/OS, AIX
