ALTER QL(CLUS_Q) CLWRANK (3) ?CHLWLUSEQ (ANY)
On QM2:
ALTER CHL (TO.QM2) CHLTYPE (CLUSRCVR) CLWLRANK (3)
ALTER QL(CLUS_Q) CLWRANK (2) ?CHLWLUSEQ (ANY)
On QM3:
ALTER CHL (TO.QM3) CHLTYPE (CLUSRCVR) CLWLRANK (3)
ALTER QL(CLUS_Q) CLWRANK (1) ?CHLWLUSEQ (ANY)
On QM3:
ALTER CHL (TO.QM4) CHLTYPE (CLUSRCVR) CLWLRANK (2)
ALTER QL(CLUS_Q) CLWRANK (3) ?CHLWLUSEQ (ANY)
To which queue manager will the messages be delivered after these changes?

A) QM1
B) QM3
C) QM4
D) QM2

2. A new publish/subscribe application is being developed which will make use of a basic broker topology consisting of a parent broker PBRK and two child brokers, C1BRK and C2BRK.
Which set of will quickly ensure the child brokers will have their necessary default objects and can communicate with the parent broker?

A) Issue the MQSC command ALTER QMGR parent (PBRK) for each child broker, then restart C1BRK and C2BRK
B) Set the child flag to true for each of the child brokers, then create the SYSTEM BROKER queues before starting each child broker
C) Create the SYSTEM BROKER queues for each child broker, then start the parent broker with the -c C1BRK, C2BRK flag
D) Create each child broker, then issue the MQSC command ALTER QMGR children (C1BRK, C2BRK) for the parent broker

3. An application publishes persistent stock quote messages every 5 seconds. The subscribers are only interested in the latest quotes. During the tests, it is found that the message delivery speed is slow. In order to improve the application performance, which of the following actions is appropriate?

A) Reduce the number of stock quote subscribers.
B) Implement MQ high availability
C) Set nonpersistent in MQMD.
D) Increase the maximum message length.

4. A financial company has decided that as part of the migration of their existing IBM WebSphere MQ V6.0 broker infrastructure to IBM WebSphere MQ V7.0 they would like to make use of the publish/subscribe clusters topology in IBM WebSphere MQ V7.0. Which MQSC command needs to be issued on all queue managers in the broker infrastructure during the migration to remove the old IBM WebSphere MQ V6.0 broker relationships?

A) ALTER QMGR PARENT (' ')
B) ALTER QMGR PARENT (' ') CHILD (' ')
C) ALTER QMGR PARENT (EMPTY)
D) ALTER QMGR PARENT (EMPTY) CHILD (NONE)

5. The administrator has to give authority for user test to browse messages in queue LQ on queue manager QM1. User test will be using MQ Explorer to browse the messages. Which commands have to be executed to achieve this?

A) MQ Explorercan'tbe used by non-mqm users
