We'll cover the following

Question 10

A solutions architect is rearchitecting an application with decoupling. The application will send batches of up to 1000 messages per second that must be received in the correct order by the consumers.

Which action should the solutions architect take?

  1. He should create an Amazon SQS Standard queue.
  2. He should create an Amazon SNS topic.
  3. He should create an Amazon SQS FIFO queue.
  4. He should create an AWS Step Functions state machine.

Correct Answer: 3

Explanation: Only FIFO queues guarantee the ordering of messages, and therefore, a standard queue would not work. The FIFO queue supports up to 3000 messages per second with batching, so this is a supported scenario.
