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, including changes to security groups, and can be used for auditing. Option A is wrong because VPC Flow Logs capture network traffic, not API activity. Option B is wrong because AWS Config can track resource configuration changes but is not primarily for auditing API calls; it focuses on compliance and configuration history. Option C is wrong because Amazon CloudWatch is for monitoring metrics and logs, not API activity.
