Question

A developer needs to build a workflow to handle messages that are sent to an Amazon Simple Queue Service (Amazon SQS) queue. When a message reaches the queue, the workflow must implement a delay before invoking an AWS Lambda function to process the message. Which solution will meet this requirement in the MOST operationally efficient way?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Set the DelaySeconds value of the SQS queue to be the number of seconds required to delay delivery of the messages. Add an event source mapping for the Lambda function. Specify the SQS queue as a source. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes.
