A developer is testing an application that invokes an AWS Lambda function asynchronously. During the testing phase, the Lambda function fails to process after two retries.
How can the developer troubleshoot the failure?
A.
Configure AWS CloudTrail logging to investigate the invocation failures.
B.
Configure Dead Letter Queues by sending events to Amazon SQS for investigation.
C.
Configure Amazon Simple Workflow Service to process any direct unprocessed events.
D.
Configure AWS Config to process any direct unprocessed events.
In AWS Lambda, you can use Dead Letter Queues (DLQ) to capture and retain events that couldn't be processed successfully after a specified number of retries. By configuring a DLQ, the failed events are sent to an Amazon SQS queue, allowing you to investigate and analyze the reasons for the failures.
Dead Letter Queues (DLQ) can be configured for Lambda functions to capture failed asynchronous invocations. Events that cannot be processed will be sent to an SQS queue (or an SNS topic) you specify, allowing for further investigation and reprocessing.
