Q4 Single choice

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 gettingmessages by message ID.
C
It ensures that any new MSGIDs are unique as well as making the retrieval of messagesbased on
message ID more efficient.
D
The queue manager will keep an index of MSGIDs that have already been used to make surethat the message ID is unique when a new message is put.
