Exam AWS-SysOps topic 1 question 750 discussion

Exam question from Amazon's AWS-SysOps
Question #: 750
Topic #: 1
[All AWS-SysOps Questions]

A SysOps Administrator deployed an AWS Elastic Beanstalk worker node environment that reads messages from an auto-generated Amazon Simple Queue
Service (Amazon SQS) queue and deletes them from the queue after processing. Amazon EC2 Auto Scaling scales in and scales out the number of worker nodes based on CPU utilization. After some time, the Administrator notices that the number of messages in the SQS queue are increasing significantly.
Which action will remediate this issue?

  • A. Change the scaling policy to scale based upon the number of messages in the queue.
  • B. Decouple the queue from the Elastic Beanstalk worker node and create it as a separate resource.
  • C. Increase the number of messages in the queue.
  • D. Increase the retention period of the queue.

Selected Answer: A
By changing the scaling policy to scale based on the number of messages in the SQS queue, you can directly address the issue of the queue growing significantly. This allows you to scale the number of worker nodes dynamically based on the queue's message count. Scaling based on the number of messages in the queue ensures that the worker nodes can handle the incoming workload and prevent the accumulation of messages, thereby maintaining a manageable queue size.

A is correct - increase workload based on messages so messages will be decreased faster.

I am curious. "Increase the retention time" won't that cause msg to stay in the queue longer. For D to be affective it should be decreased. I think A is the better option
