Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 682 discussion

IAM Policy and AWS Config (Option A): By creating an IAM policy that allows users to create only encrypted EBS volumes, you proactively prevent the creation of unencrypted volumes. Using AWS Config, you can set up rules to detect noncompliant resources, and AWS Systems Manager Automation can be used for automated remediation. This approach provides a proactive and automated solution.

Isn't B simpler?

B: Too much work C: Macie is for PII and sensitive data not for encrypted volumes D: Inspector for OS patching and vulnerability detections

why not B?

Option A - enforces the creation of encrypted volumes via IAM policies and uses AWS Config for detection and AWS Systems Manager for remediation with the LEAST administrative overhead.

A as exactly described here: https://docs.aws.amazon.com/prescriptive-guidance/latest/patterns/automatically-encrypt-existing-and-new-amazon-ebs-volumes.html Not B, that could in theory work but would be massive operational overhead Not C, Macie detects PII data, not unencrypted volumes Not D, Inspector detects vulnerabilities, not unencrypted volumes
