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
✓
Amazon CloudWatch Logs
CloudTrail records S3 API calls, and CloudWatch Logs can be used to store and monitor those logs. Config records configuration changes, not data access. S3 server access logs record object-level access, but the question asks for auditing access; CloudTrail with CloudWatch Logs is a common solution. S3 Inventory provides metadata, not access logs.
