Selected Answer: C
VPC Flow Logs capture information about the IP traffic going to and from network interfaces in a VPC. This includes traffic that traverses a VPN connection. VPC Flow Logs can be used to monitor and troubleshoot connectivity issues, including verifying whether traffic is reaching a particular subnet within the VPC.

Selected Answer: C
VPC Flow Logs capture detailed information about the traffic flowing to and from network interfaces in a VPC. D) Eliminated - AWS CloudTrail logs record API-level activity in an AWS account, hey do not provide network-level traffic details for verifying traffic reaching specific subnets.
