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
Options A and E are correct. AWS CloudTrail records API calls to S3 and RDS, and Amazon CloudWatch Logs can store and monitor those logs. Option B (AWS Config) records resource configuration changes, not API calls, so it is incorrect. Option C (Amazon GuardDuty) is a threat detection service, not for auditing API calls. Option D (Amazon Macie) is for data classification and protection, not for recording API calls.
