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 IAM policies to restrict who can update stacks and require approval.
Options B, D, and E are correct. IAM policies enforce least privilege and require approval for updates (B), stack policies protect critical resources from accidental changes (D), and change sets allow review and approval before execution (E). Option A (drift detection) is a monitoring tool, not a change management control. Option C (nested stacks) promotes template reuse but does not enforce change management processes.
