A
Amazon CloudWatch Logs
B
AWS CloudTrail
C
VPC Flow Logs
D
AWS Identity and Access Management (IAM)
Explanation:
VPC Flow Logs is the correct AWS service that captures information about the IP traffic going to and from network interfaces in your VPC.
Key points about VPC Flow Logs:
-
Captures network flow data for VPCs, subnets, and network interfaces
-
Records source/destination IP addresses, ports, protocol, and traffic action (accept/reject)
-
Helps with troubleshooting connectivity and security issues
-
Can be published to Amazon CloudWatch Logs or Amazon S3
Why other options are incorrect:
-
Amazon CloudWatch Logs: A log management service, but doesn't specifically capture network traffic flow data
-
AWS CloudTrail: Records API calls and management events, not network traffic
-
AWS IAM: Manages access control and permissions, not network traffic logging
