   You have two on-premises sites (Site A and Site B) connected to Google Cloud via separate VPN tunnels, each configured as a hybrid spoke in Network Connectivity Center. Site A can reach Google Cloud VMs, and Site B can reach Google Cloud VMs, but Site A cannot reach Site B. You have verified that both VPN tunnels are healthy and that the hub is configured correctly. What is the most likely cause of this issue?

   • AThe hub is not configured to allow transitivity between hybrid spokes.
   • BThe on-premises routers at Site A and Site B do not have routes for each other's subnets via the VPN tunnels.
   • CThe Google Cloud VPC has a firewall rule blocking traffic between the two on-premises subnets.
   • DThe VPN tunnels are using different IKE versions.

   Your company has two on-premises data centers in Frankfurt and London, each connected to Google Cloud via a single Cloud VPN tunnel. You are configuring Network Connectivity Center to enable site-to-site data transfer between the two data centers through Google Cloud. You have already created a hybrid spoke for the Frankfurt VPN tunnel. What must you do next to complete the configuration?

   • AConfigure a router appliance spoke in London to terminate the VPN tunnel.
   • BCreate a VLAN attachment for the London VPN tunnel and attach it to the hub.
   • CCreate a second hybrid spoke for the London VPN tunnel and attach it to the same hub.
   • DAdd the London VPN tunnel as a second interface on the existing Frankfurt hybrid spoke.

   Your organization has a Dedicated Interconnect connection to Google Cloud. You need to connect two on-premises VLANs (VLAN 100 and VLAN 200) to two different VPCs (VPC-A and VPC-B) using Network Connectivity Center. What is the correct configuration?

   • ACreate two router appliance spokes, one for each VLAN, and attach them to the hub.
   • BCreate a single VLAN attachment for both VLANs and attach it to a hybrid spoke.
   • CCreate a single hybrid spoke and add both VLAN attachments to it.
   • DCreate two VLAN attachments, one for each VLAN, and attach each to a separate hybrid spoke on the same hub.

   You have a router appliance spoke in Network Connectivity Center that is advertising the on-premises subnet 10.0.0.0/8. You also have a hybrid spoke for a VPN tunnel that is advertising the same subnet 10.0.0.0/8. Both spokes are attached to the same hub. Traffic from Google Cloud VMs destined for 10.0.0.5 is being sent to the VPN tunnel instead of the router appliance, which is the preferred path. What is the most likely cause?

   • AThe router appliance is not attached to the hub correctly.
   • BThe VPN tunnel is using a dynamic routing protocol, while the router appliance is using static routes.
   • CThe router appliance spoke is not advertising a more specific route (e.g., 10.0.0.0/16) for the destination.
   • DThe VPN tunnel has a lower cost than the router appliance.
