A developer is creating an AWS Lambda function that consumes messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The developer notices that the Lambda function processes some messages multiple times. How should developer resolve this issue MOST cost-effectively?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Change the Amazon SQS standard queue to an Amazon SQS FIFO queue by using the Amazon SQS message deduplication ID. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. This option delivers the requirement at the lowest cost.
