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 all API calls made to AWS services and stores them in Amazon S3 for auditing and compliance. AWS Config monitors resource configurations, not API calls. Amazon VPC Flow Logs capture IP traffic information. Amazon CloudWatch Logs stores log data but does not natively capture API calls; it can receive logs from CloudTrail if integrated, but CloudTrail is the primary service for capturing API calls.
