Answers
A.

Answers

C.
For transient queues, the message will be processed after the system comes online
Answers
C.
For transient queues, the message will be processed after the system comes online
D.
For any type of queue, the message will be lost
Answers
D.
For any type of queue, the message will be lost
Suggested answer: B

Explanation:

In case of a system failure, in-flight messages in persistent VM queues that have been consumed will be processed after the system comes online. This is because persistent VM queues store messages on disk and guarantee delivery even if there is a system crash or restart. Therefore, any in-flight messages that have been consumed but not processed will be recovered from disk and processed when the system is back online.
