PAS-C01 Operations and Maintenance Practice Question

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
✓
VPC Flow Logs
VPC Flow Logs capture metadata about IP traffic within the VPC, including accepted and rejected connections. By analyzing flow logs, you can identify packet loss, rejected requests, or other connectivity issues between subnets. Option A (AWS Direct Connect) is for dedicated on-premises connectivity, not for internal VPC traffic. Option C (AWS CloudTrail) records API calls, not network traffic. Option D (AWS Site-to-Site VPN) is for connecting remote networks, not for analyzing internal VPC paths.
