AWS Certified Developer - Associate DVA-C02 — Topic 1 Question 191

Question

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?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Configure Dead Letter Queues by sending events to Amazon SQS for investigation. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. AWS Config tracks resource configuration changes and evaluates compliance. This option decouples the components so they scale independently and absorb load spikes.
