Exam AWS Certified Developer Associate topic 1 question 134 discussion

Exam question from Amazon's AWS Certified Developer Associate
Question #: 134
Topic #: 1
[All AWS Certified Developer Associate Questions]

A company created an application to consume and process data. The application uses Amazon Simple Queue Service (Amazon SQS) and AWS Lambda functions. The application is currently working as expected, but it occasionally receives several messages that it cannot process properly. The company needs to clear these messages to prevent the queue from becoming blocked.
A developer must implement a solution that makes queue processing always operational. The solution must give the company the ability to defer the messages with errors and save these messages for further analysis.
What is the MOST operationally efficient solution that meets these requirements?

  • A. Configure Amazon CloudWatch Logs to save the error messages to a separate log stream.
  • B. Create a new SQS queue. Set the new queue as a dead-letter queue for the application queue. Configure the Maximum Receives setting.
  • C. Change the SQS queue to a FIFO queue. Configure the message retention period to 0 seconds.
  • D. Configure an Amazon CloudWatch alarm for Lambda function errors. Publish messages to an Amazon Simple Notification Service (Amazon SNS) topic to notify administrator users.

It is possible to create another SQS Queue to send failed and error messages. This Queue is called DLQ (Dead-Letter-Queue). We can also set the maximum number of messages that can be read from the queue given the issues. For me is B

B. Create a new SQS queue. Set the new queue as a dead-letter queue for the application queue. Configure the Maximum Receives setting is the MOST operationally efficient solution that meets these requirements. By creating a new SQS queue and setting it as a dead-letter queue for the application queue, messages that cannot be processed successfully by the application will be automatically sent to the dead-letter queue. This allows the application to continue processing other messages in the main queue without being blocked.

The main keywords here are "save these messages for further analysis" so DLQ is always a good option in this kind of question

Dead-letter queues are useful for debugging your application or messaging system because they let you isolate unconsumed messages to determine why their processing doesn't succeed.
