SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A multinational corporation is implementing a multi-account AWS strategy using AWS Organizations. The security team requires that all newly created accounts in the organization automatically have an Amazon GuardDuty detector enabled in all enabled Regions. Which solution meets this requirement with the LEAST operational overhead?
⚠ Common exam trap
Candidates often choose the Config + Lambda option (D) thinking it is fully automated, but they overlook that it is reactive and incurs ongoing evaluation costs, whereas StackSets provide a proactive, single-deployment solution with lower operational overhead.

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 CloudFormation StackSets with a stack that includes an AWS::GuardDuty::Detector resource, and apply it to the organization root OU.
AWS CloudFormation StackSets can be applied to the organization root OU, automatically deploying an AWS::GuardDuty::Detector resource to every account in the organization as new accounts are created. This approach requires no manual intervention per account, and StackSets handle the lifecycle of the detector across all enabled Regions with minimal operational overhead.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use AWS CloudFormation StackSets with a stack that includes an AWS::GuardDuty::Detector resource, and apply it to the organization root OU.
Why this is correct
Correct: StackSets automate deployment across accounts; the resource creates the detector.
- ✗
Use AWS Service Catalog to publish a GuardDuty product and require account owners to launch it.
Why it's wrong here
Requires manual action per account.
- ✗
Use an SCP that denies guardduty:DeleteDetector and guardduty:UpdateDetector actions, then have each account administrator manually enable GuardDuty.
Why it's wrong here
Manual step is not automated.
- ✗
Use AWS Config rules to detect accounts without GuardDuty enabled and trigger a Lambda function to enable it.
Why it's wrong here
Reactive, not proactive.
