A Solutions Architect Is Designing an Application for a Two-Step

A solutions architect is designing an application for a two-step order process. The first step is synchronous and must return to the user with little latency. The second step takes longer, so it will be implemented in a separate component. Orders must be processed exactly once and in the order in which they are received. How should the solutions architect integrate these components?

A) Use Amazon SQS FIFO queues.
B) Use an AWS Lambda function along with Amazon SQS standard queues.
C) Create an SNS topic and subscribe an Amazon SQS FIFO queue to that topic.
D) Create an SNS topic and subscribe an Amazon SQS Standard queue to that topic.
