What is the purpose of an Amazon SQS delay queue?

• A. Messages are hidden for a configurable period when first added to the queue. ✓
• B. Messages are hidden for a configurable period after being consumed from the queue.
• C. Consumers can poll the queue for a configurable period before retrieving messages.
• D. Messages cannot be deleted for a configurable period after being consumed from the queue.

Correct Answer: A. Messages are hidden for a configurable period when first added to the queue.

Explanation

The primary purpose of an Amazon SQS delay queue is to hide messages for a specified, configurable period when they are first added to the queue. This means the messages are not immediately visible or processable by consumers during the delay period. Option B incorrectly describes hiding messages after consumption, which does not align with the definition of a delay queue. Option C mischaracterizes polling duration as the core function of a delay queue. Option D incorrectly states that messages cannot be deleted post-consumption — this is unrelated to delay queue functionality. Therefore, the correct answer is A. 【Provided by Lantern Certification: swufelp1999】
