SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A multinational corporation uses AWS Organizations with hundreds of accounts. The security team requires that all Amazon S3 buckets across the organization be encrypted with a specific AWS KMS key from the security account. Which combination of controls should be implemented to enforce this requirement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply an SCP to deny s3:PutBucketEncryption with any key other than the required KMS key, and use AWS Config rules to detect and remediate existing non-compliant buckets.
SCPs can deny the creation of S3 buckets without encryption or with the wrong KMS key, and AWS Config rules can detect non-compliant existing buckets for remediation. Option A is wrong because AWS Service Catalog is not designed for this purpose. Option B is wrong because IAM policies alone cannot enforce encryption at the organizational level across multiple accounts. Option C is wrong because AWS CloudTrail only logs, not enforces.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an AWS Service Catalog portfolio that restricts bucket creation to encrypted buckets only.
Why it's wrong here
AWS Service Catalog is not designed to enforce encryption policies across accounts at the organizational level.
- ✗
Use IAM policies in each account to deny PutBucketEncryption actions that do not specify the required KMS key.
Why it's wrong here
IAM policies alone cannot enforce encryption across multiple accounts; they are scoped to a single account.
- ✗
Enable AWS CloudTrail and create a CloudWatch Events rule to automatically remediate non-compliant buckets.
Why it's wrong here
AWS CloudTrail only logs API activity, it does not enforce or prevent actions.
- ✓
Apply an SCP to deny s3:PutBucketEncryption with any key other than the required KMS key, and use AWS Config rules to detect and remediate existing non-compliant buckets.
Why this is correct
SCPs can deny actions organization-wide, and AWS Config rules can detect and remediate non-compliant buckets.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
