How is a processed SQS message removed from the queue?

  1. By moving it to the dead-letter queue
  2. By acknowledging it during ReceiveMessage
  3. By calling DeleteMessage, or automatically on success in some SDKs
  4. By letting the visibility timeout expire
Show the answer

Answer: C. By calling DeleteMessage, or automatically on success in some SDKs

A message stays in the queue until it is deleted; letting the timeout lapse makes it visible again rather than removing it.
