AWS Certified Developer Associate DVA-C02 Practice Question

A developer is building an application that uses an AWS Lambda function to process images uploaded to an Amazon S3 bucket. The function is invoked asynchronously. Occasionally, malformed image files cause the function to fail repeatedly. The developer needs a way to automatically isolate these failed events for later analysis without losing the event data. What is the most effective solution?

  • Configure a Lambda destination with a condition of 'On Success' to route failed events.

  • Increase the function's memory and timeout values in the function configuration.

  • Configure a dead-letter queue (DLQ) on the Lambda function to send the failed events to an Amazon SQS queue.

  • Enable active tracing with AWS X-Ray for the Lambda function to capture the exceptions.
