Explanation:
The correct answer is B. In AWS Lambda, Dead Letter Queues (DLQ) can be configured to capture events that couldn't be processed successfully after a specified number of retries. By setting up a DLQ with Amazon SQS, failed events will be sent to the SQS queue, allowing you to investigate and analyze the reasons for the failures.
How can a developer troubleshoot an AWS Lambda function that fails to process events after two asynchronous retries?
A
Enable AWS CloudTrail logging for invocation failure analysis.
B
Set up Dead Letter Queues with Amazon SQS to capture and investigate unprocessed events.
C
Utilize Amazon Simple Workflow Service for handling direct unprocessed events.
D
Implement AWS Config to manage and examine unprocessed events.
