Question # 6

A space exploration company receives telemetry data from multiple satellites. Smallpackets of data are received through Amazon API Gateway and are placed directly into anAmazon Simple Queue Service (Amazon SQS) standard queue. A custom application issubscribed to the queue and transforms the data into a standard format.Because of inconsistencies in the data that the satellites produce, the application isoccasionally unable to transform the data. In these cases, the messages remain in theSQS queue. A DevOps engineer must develop a solution that retains the failed messagesand makes them available to scientists for review and future processing.Which solution will meet these requirements?

A. Configure AWS Lambda to poll the SQS queue and invoke a Lambda function to checkwhether the queue messages are valid. If validation fails, send a copy of the data that is notvalid to an Amazon S3 bucket so that the scientists can review and correct the data. Whenthe data is corrected, amend the message in the SQS queue by using a replay Lambdafunction with the corrected data.
B. Convert the SQS standard queue to an SQS FIFO queue. Configure AWS Lambda topoll the SQS queue every 10 minutes by using an Amazon EventBridge schedule. Invokethe Lambda function to identify any messages with a SentTimestamp value that is olderthan 5 minutes, push the data to the same location as the application's output location, andremove the messages from the queue.
C. Create an SQS dead-letter queue. Modify the existing queue by including a redrivepolicy that sets the Maximum Receives setting to 1 and sets the dead-letter queue ARN tothe ARN of the newly created queue. Instruct the scientists to use the dead-letter queue toreview the data that is not valid. Reprocess this data at a later time.
D. Configure API Gateway to send messages to different SQS virtual queues that arenamed for each of the satellites. Update the application to use a new virtual queue for anydata that it cannot transform, and send the message to the new virtual queue. Instruct thescientists to use the virtual queue to review the data that is not valid. Reprocess this data ata later time.
