PAS-C01 Operations and Maintenance Practice Question

An SAP system running on AWS is experiencing intermittent connectivity issues between the application server and the database server. Both servers are in the same VPC but different subnets. The security groups and network ACLs are correctly configured. Which AWS service can help diagnose the network path and identify packet loss?

Answer choices

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.
