Question #: 494
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

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?

  • A. Create an AWS Step Functions state machine to process the SQS queue. Use a Wait state to delay the Lambda function’s processing for the required number of seconds after message delivery to the SQS queue. Use Amazon EventBridge to invoke the state machine every 5 minutes.
  • B. Configure the Lambda function to poll the SQS queue. Update the Lambda code to republish each message with a custom attribute that contains a future time when the message should be fully processed. Update the Lambda code to fully process messages when the custom attribute’s future time has passed.
  • 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.
  • D. Set the Visibility Timeout 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.
