I will got with B just to identify what happend in the network level

I suspect that there is a mistake in the issue and that the Network Intelligence Center is correct, not the Network Connectivity Center. https://cloud.google.com/network-intelligence-center/docs/connectivity-tests/concepts/overview

To identify and troubleshoot the network connectivity issue between Google Kubernetes Engine (GKE) clusters in different VPCs where nodes in Cluster A cannot access nodes in Cluster B, the recommended action is to use Network Connectivity Center, as stated in (Option B). By performing a Connectivity Test from Cluster A to Cluster B using Network Connectivity Center, you can assess the network path and identify potential issues affecting the connectivity. This diagnostic tool helps pinpoint where the connectivity breaks down, enabling you to analyze the network configuration and resolve any misconfigurations or obstacles that might be hindering communication between the clusters. This approach provides a focused and efficient way to troubleshoot the specific network layer where the connectivity issue occurs without requiring execute access to workloads and nodes in the clusters.

Network Connectivity Center is not the greatest tool but in this case we don't really have any options with the restrictions in the question so B

B as the Q says but do not have execute access to workloads and nodes… so can’t run toolbox
