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 CloudTrail
AWS CloudTrail records API calls for all AWS services, including Network Load Balancer (NLB) operations. Therefore, to audit NLB operations, CloudTrail should be used. Option B (Amazon CloudWatch Logs) stores logs but does not natively capture API calls. Option C (AWS Config) tracks resource configurations and changes, not API operations. Option D (VPC Flow Logs) captures network traffic information, not API calls. Hence, Option A is correct.
