You have configured a service on Google Cloud that connects to an on-premises service via a Dedicated Interconnect. Users are reporting recent connectivity issues. You need to determine whether the traffic is being dropped because of firewall rules or a routing decision. What should you do?
To determine whether the traffic being dropped is due to firewall rules or a routing decision, you should use the Network Intelligence Center Connectivity Tests. This tool allows you to perform end-to-end connectivity tests between the VPC and the on-premises network, enabling you to diagnose issues related to network configuration, including firewall settings and routing paths.
