Question #: 14
Topic #: 1

You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.
Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)

A. AUTO_ACKNOWLEDGE
B. CLIENT_ACKNOWLEDGE
C. DUPS_OK_ACKNOWLEDGE
D. DEFAULT_ACKNOWLEDGE

Show Suggested Answer

Suggested Answer: B 🗳️
With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge.
Incorrect Answers:
A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.
C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.
D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.

For the below statement, it should be AUTO_ACKNOWLEDGE instead of CLIENT_ACKNOWLEDGE : A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.
