Oracle WebLogic Server 12c: Advanced Administration II — Question 2

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.)

Answer options

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

Correct answer: B

Explanation

The correct answer is B: CLIENT_ACKNOWLEDGE, as this mode requires the client to explicitly acknowledge the receipt of messages. The other options, such as AUTO_ACKNOWLEDGE and DUPS_OK_ACKNOWLEDGE, do not allow for manual acknowledgment by the client, while DEFAULT_ACKNOWLEDGE is not a recognized acknowledgment mode in JMS.
