Validate that your Google Cloud network allows traffic from cloud resources to on-premises and diagnose potential configuration failures without sending data-plane test traffic. What should you use?

Network Topology visualizations in Network Intelligence Center allow you to understand your network architecture and traffic flows between resources, including connections to on-premises networks, without generating actual data-plane traffic. You can visually inspect the paths and identify potential misconfigurations or blocks. Connectivity Tests, while useful for validating connectivity, actively send synthetic packets and are not suitable for diagnosing without sending data. Packet Mirroring captures actual traffic for analysis but requires traffic to be sent, which the question explicitly avoids. VPC Flow Logs record network flow information but also require traffic to be sent through the network to generate logs.
