Correct answer & explanation
✓
VPC Flow Logs
VPC Flow Logs capture IP traffic information for network interfaces in a VPC. Option B is wrong because AWS Config tracks resource configuration changes, not network traffic. Option C is wrong because CloudTrail records API calls, not IP traffic. Option D is wrong because CloudWatch Logs can store logs but does not capture network traffic; it is a destination for logs, not a traffic capture service.
