Q: Does Amazon SQS guarantee delivery of messages?
Standard queues provide at-least-once delivery, which means that each message is delivered at least once.
FIFO queues provide exactly-once processing, which means that each message is delivered once and remains available until a consumer processes it and deletes it. Duplicates are not introduced into the queue.
D is the correct answer – read the documentation, it’s NOT a FIFO queue
