Correct answer & explanation
✓
AWS CloudTrail event history
D, and E are correct. CloudTrail logs all API calls, including who made the call. CloudTrail event history provides a view of the last 90 days. AWS Config records configuration changes, including security group creation. Option B is wrong because CloudWatch Logs does not capture API calls unless specifically configured. Option C is wrong because VPC Flow Logs capture network traffic, not API calls.
