It assesses reachability by analyzing\nyour network configuration and, in certain use cases, by sending probe packets.\n\nThe following documentation describes several common use cases for\nConnectivity Tests:\n\n- [Test connectivity within Virtual Private Cloud (VPC) networks](/network-intelligence-center/docs/connectivity-tests/concepts/test-within-vpc-networks),\n including networks that use Shared VPC and VPC Network Peering.\n This use case describes a full end-to-end testing scenario, including the test\n results provided in the Google Cloud console.\n\n- [Test connectivity to and from Google-managed services](/network-intelligence-center/docs/connectivity-tests/concepts/test-google-managed-services)\n\n- [Test connectivity from a VPC network to a non-Google Cloud network](/network-intelligence-center/docs/connectivity-tests/concepts/test-between-networks),\n such as an on-premises data center\n\n- [Test connectivity from a non-Google Cloud network to a VPC network](/network-intelligence-center/docs/connectivity-tests/concepts/test-between-networks#non-gcp2vpc)\n\n- [Test connectivity between two non-Google Cloud networks](/network-intelligence-center/docs/connectivity-tests/concepts/test-between-networks#non-gcp2non-gcp)\n\n- [Test connectivity from VM to VM through a Network Connectivity Center hub](/network-intelligence-center/docs/connectivity-tests/concepts/test-through-ncc-hub)\n\n- [Test connectivity to Google Cloud load balancers](/network-intelligence-center/docs/connectivity-tests/concepts/test-load-balancers)\n\nTo troubleshoot these scenarios, see [Detect invalid or inconsistent configurations](/network-intelligence-center/docs/connectivity-tests/concepts/detecting-configs).\n\nWhat's next\n-----------\n\n- [Learn about Connectivity Tests](/network-intelligence-center/docs/connectivity-tests/concepts/overview)\n- [Troubleshoot Connectivity Tests](/network-intelligence-center/docs/connectivity-tests/support/troubleshooting)"]]
