Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 310 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 310
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer is building an application that invokes AWS Lambda functions asynchronously to process events. The developer notices that a Lambda function fails to process some events at random times. The developer needs to investigate the failed events and capture the events that the Lambda function fails to process.

Which solution will meet these requirements?

  • A. Add an Amazon EventBridge rule for the Lambda function. Configure the EventBridge rule to react to failed events and to store the events in an Amazon DynamoDB table.
  • B. Configure the Lambda function with a dead-letter queue based in Amazon Kinesis. Update the Lambda function's execution role with the required permissions.
  • C. Configure the Lambda function with an Amazon Simple Queue Service (Amazon SQS) dead-letter queue. Update the Lambda function's execution role with the required permissions.
  • D. Configure the Lambda function with an Amazon Simple Queue Service (Amazon SQS) FIFO dead-letter queue. Update the Lambda function's execution role with the required permissions.

The standard SQS dead-letter queue should capture the failed events and let the developer debug them, so C is the right solution. B - There's no such thing as a DLQ in Kinesis. D - SQS FIFO DLQ would be too much overkill for this task because you don't need ordering or deduplication. A - This would involve additional costs and too much complexity to use a DynamoDB table for this.

Selected Answer: C
Using an SQS queue for a DLQ is simpler than using Amazon Kinesis. Kinesis is a more complex service designed for real-time data streaming, which might be overkill for simply capturing failed Lambda events.
