    SQS doesn’t follow first in first out sequence but all the messages are delivered

    D

    At-Least-Once Delivery: A message is delivered at least once, but occasionally more than one copy or a message is delivered.
    Best-Effort Ordering: Occasionally, messages are delivered in an order different from which they were sent.

    D.

    SQS Messages can be delivered multiple times and in any order.

    For what is worth SQS Now has FIFO Queues (NEW) (https://aws.amazon.com/sqs/faqs/)
    which is basically a FIFO with SINGLE MESSAGE DELIVERY

    Anyway…option D should be fine

  8. BDA says:

    D, because a Standard SQS Queue will deliver messages one, or more times, in an indeterminate order.

    FIFO queues deliver messages exactly once, in order.

  9. Abdul says:

    I’ve heard FIFO is announced in the recent re:invent.

    BTW….I think D is the correct answer.
