SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A company has multiple AWS accounts managed via AWS Organizations. The security team wants to enforce that all S3 buckets across all accounts are encrypted with AWS KMS keys managed by the security team. What is the MOST scalable and maintainable solution?
⚠ Common exam trap
The trap is that candidates may think an SCP is the only scalable solution, but in this case the SCP described uses the wrong actions. Option C with AWS Config and auto-remediation is a valid and scalable enforcement mechanism.
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
✓
Use AWS Config rules in each account to detect non-compliant buckets and trigger auto-remediation.
Using AWS Config rules deployed via StackSets across all accounts in the organization provides a scalable and maintainable way to detect non-compliant buckets (e.g., those without SSE-KMS encryption) and trigger auto-remediation to enforce encryption. This approach is proactive and centralized, while still being scalable via AWS Organizations. Option A is incorrect because the SCP actions mentioned (s3:PutBucketAcl and s3:PutBucketPolicy) do not control encryption settings. Option B is only detective and does not enforce compliance. Option D does not address encryption enforcement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Apply a service control policy (SCP) at the root OU that denies s3:PutBucketAcl or s3:PutBucketPolicy actions unless encryption is configured.
Why it's wrong here
This is incorrect because the SCP actions listed (s3:PutBucketAcl and s3:PutBucketPolicy) do not control encryption. To enforce encryption, an SCP should deny s3:PutBucketEncryption or s3:PutObject with conditions on KMS key usage.
- ✗
Use AWS Trusted Advisor to check for unencrypted buckets and notify the security team.
Why it's wrong here
Incorrect. Trusted Advisor only checks for unencrypted buckets and notifies; it does not enforce compliance, making it less effective for enforcement.
- ✓
Use AWS Config rules in each account to detect non-compliant buckets and trigger auto-remediation.
Why this is correct
Correct. AWS Config rules can be deployed across all accounts using StackSets, detect non-compliant buckets, and trigger auto-remediation to apply encryption, providing scalable and maintainable enforcement.
- ✗
Create a CloudFormation StackSet that deploys an S3 bucket policy in every account.
Why it's wrong here
Incorrect. A CloudFormation StackSet deploying bucket policies does not enforce encryption; it only manages bucket policies, which are separate from encryption configuration.
Quick reference
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 |
