QUESTION 41

An application is being designed which will send updates about customers to different applications. Given the sensitive nature of the data, the sending application needs to manage which applications receive the datA. Which of the following is the best solution to ensure this?

 

A.

Apply the publish-subscribe paradigm (one-to-many).

C.

All applications should listen on the same queue and after processing the message should update its header so the last application process can remove it from the queue

D.

All receiving applications should listen on the same queue and the sending application should send separate copies of the message with attributes which allow the receiving applications to search the queue for their own copies.

QUESTION 43

In designing a solution with availability in mind, the designer is considering the following two alternatives, one using a cluster queue and the other using a shared queue. In each scenario, Queue Managers QMA and QMB will both be capable of running Application A. In the first scenario, App
lication A will run on QMA and QMB on Windows accessing cluster queue QA. In the second scenario, Application A will run on QMA and QMB on z/OS accessing shared queue QA. Which of the following describes the availability scenarios in the situation where QMA fails?

 

A.

For Windows, the delivered messages on QA that Application A on QMA did not get to process are available for processing by Application A on QMB.

B.

For z/OS, the delivered messages on QA that Application A on QMA did not get to process are available for processing by Application A on QMB.

C.

For Windows, messages from QA that were in flight on QMA when it failed are made available for processing on QMB.

D.

For z/OS, messages from QA that were in flight on QMA when it failed are unavailable for processing by QMB.

QUESTION 45

A solution designer has requested that several queues on a z/OS queue manager be defined with index type set to message ID, i.e., INDXTYPE(MSGID). Why would a designer use this setting?

 

A.

It creates a permanent index of MSGIDs that are currently in use for this queue.

B.

It allows MQGET commands to have significantly improved performance when getting messages by message ID.

C.

It ensures that any new MSGIDs are unique as well as making the retrieval of messages based on message ID more efficient.

D.

The queue manager will keep an index of MSGIDs that have already been used to make sure that the message ID is unique when a new message is put.

 

Correct Answer: B

Use action indicator in MQPMO, provide new MQMD for reply message and use MQPMO_NEW_MSG_ID in the MQPUT options.

C.

Reuse the MQMD and honor the report options set in the request message.
