AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 242

A company's DevOps team manages a set of AWS accounts that are in an organization in AWS Organizations.

The company needs a solution that ensures that all Amazon EC2 instances use approved AM Is that the DevOps team manages. The solution also must remediate the usage of AMIs that are not approved. The individual account administrators must not be able to remove the restriction to use approved AMIs.

Which solution will meet these requirements?

Answer options

• A. Use AWS CloudFormation StackSets to deploy an Amazon EventBridge rule to each account. Configure the rule to react to AWS CloudTrail events for Amazon EC2 and to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the DevOps team to the SNS topic.
• B. Use AWS CloudFormation StackSets to deploy the approved-amis-by-id AWS Config managed rule to each account. Configure the rule with the list of approved AMIs. Configure the rule to run the AWS-StopEC2Instance AWS Systems Manager Automation runbook for the noncompliant EC2 instances.
• C. Create an AWS Lambda function that processes AWS CloudTrail events for Amazon EC2. Configure the Lambda function to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the DevOps team to the SNS topic. Deploy the Lambda function in each account in the organization. Create an Amazon EventBridge rule in each account. Configure the EventBridge rules to react to AWS CloudTrail events for Amazon EC2 and to invoke the Lambda function.
• D. Enable AWS Config across the organization. Create a conformance pack that uses the approved-amis-by-id AWS Config managed rule with the list of approved AMIs. Deploy the conformance pack across the organization. Configure the rule to run the AWS-StopEC2lnstance AWS Systems Manager Automation runbook for the noncompliant EC2 instances.

Correct answer: D

Explanation

The correct answer is D because enabling AWS Config with a conformance pack ensures that compliance is enforced organization-wide and allows for automatic remediation of noncompliant instances. Options A and C focus on notifications and event reactions without enforcing compliance, while option B does not cover the organization-wide deployment aspect as effectively as option D.
