DBS-C01 Database Security Practice Question
A company needs to audit access to an Amazon DynamoDB table. The audit should capture which IAM user or role performed each action. Which AWS service should be used?
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 is the correct service because it records API calls made to DynamoDB and captures the IAM user or role that performed each action. VPC Flow Logs (Option A) capture network traffic metadata, not API calls. Amazon GuardDuty (Option C) is a threat detection service that monitors for malicious activity, not API auditing. AWS Config (Option D) tracks resource configuration changes, not API call details.
