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
✓
AWS Config with a managed rule to detect internet gateways and an automatic remediation action to detach them.
AWS Config rules can evaluate compliance of resources and trigger automatic remediation actions. A managed rule such as 'restricted-common-ports' or a custom rule can detect VPCs with internet gateways, and an accompanying remediation action can automatically detach them. Option A (Amazon GuardDuty) is a threat detection service, not a configuration compliance tool. Option B (AWS CloudTrail) logs API calls but does not evaluate current resource configurations. Option C (Service control policies, SCPs) define permissions boundaries but cannot detect or remediate existing non-compliant resources. Option D is correct.
