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 SCPs to deny access from external accounts.
SCPs can deny access from external accounts, limiting S3 bucket access to authorized accounts. Option C is correct because S3 bucket policy with aws:SourceAccount condition restricts access to specific AWS accounts. Options B, D, and E are incorrect: B (VPC endpoints with bucket policies) controls network-level access but not account-level; D (CloudTrail logging) only logs access, does not enforce perimeter; E (AWS Network Firewall) is for network traffic inspection, not account-based control.
