Question 100
A business continuity assessment identifies the following constraint, the decisive constraint is: Governance engineers must prevent creation of prohibited public resources in supported accounts. Which architecture decision most directly satisfies the requirement?
Explanation
Correct Answer
Apply relevant preventive controls and complementary SCP or policy guardrails. Preventive guardrails block unauthorized actions instead of only reporting after deployment.
Incorrect Answers
Use applicable AWS Control Tower detective controls backed by supported AWS Config mechanisms would address a different requirement: Security wants to detect deviation from required resource configuration within enrolled accounts. Detective controls evaluate drift rather than simply preventing API calls.
This alternative, Establish an AWS Control Tower landing zone with governed account enrollment, is appropriate when A regulated enterprise needs repeatable baseline accounts, log archive, audit roles, and guardrails. Control Tower orchestrates standardized account baselines and governance controls.
For the separate situation An account created outside the standard platform violates Control Tower controls and must join governance, Enroll or register the existing account in the Control Tower landing zone using supported procedures could be useful. Enrollment brings a member account under landing-zone guardrails without assuming it was originally vended.
