Exam AWS DevOps Engineer Professional topic 1 question 42 discussion

Exam question from Amazon's AWS DevOps Engineer Professional
Question #: 42
Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A company has multiple development teams sharing one AWS account. The development team's manager wants to be able to automatically stop Amazon EC2 instances and receive notifications if resources are idle and not tagged as production resources.
Which solution will meet these requirements?

  • A. Use a scheduled Amazon CloudWatch Events rule to filter for Amazon EC2 instance status checks and identify idle EC2 instances. Use the CloudWatch Events rule to target an AWS Lambda function to stop non-production instances and send notifications.
  • B. Use a scheduled Amazon CloudWatch Events rule to filter AWS Systems Manager events and identify idle EC2 instances and resources. Use the CloudWatch Events rule to target an AWS Lambda function to stop non-production instances and send notifications.
  • C. Use a scheduled Amazon CloudWatch Events rule to target a custom AWS Lambda function that runs AWS Trusted Advisor checks. Create a second CloudWatch Events rule to filter events from Trusted Advisor to trigger a Lambda function to stop idle non-production instances and send notifications.
  • D. Use a scheduled Amazon CloudWatch Events rule to target Amazon Inspector events for idle EC2 instances. Use the CloudWatch Events rule to target the AWS Lambda function to stop non-production instances and send notifications.

C is the correct answer. Trusted Advisor is used to diagnose issues with your infrastructure including idle EC2 instances.

This makes A wrong: CloudWatch Events rule to filter for Amazon EC2 >>>INSTANCE STATUS CHECKS AND IDENTIFY IDLE<<< EC2 instances ???? There are two types of status checks: system status checks and instance status checks, AND NONE of them has the "Idle" status https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-system-instance-status-check.html#types-of-instance-status-checks

CloudWatch does not have a built-in event that specifically identifies the idle status of EC2 instances, agreed. However, you can create a custom event using CloudWatch Events and a Lambda function to identify idle instances by monitoring for specific conditions that indicate an idle status, such as low CPU/network usage

I agree. However, the option C is doing what you suggested, but using Trust Advisor instead of CloudWatch. A did not say that it will use CloudWatch Event + Lambda function
