A. B. C. D.B.
The correct answer is B. Verify that both projects are in a GCP Organization. Share the VPC from one project and request that the Compute Engine instances in the other project use this shared VPC.
Explanation:
In this scenario, we have two groups of Compute Engine instances running in their own VPC, which are located in two different GCP projects. In order to enable traffic between the instances in both VPCs, we need to establish a connection between them.
The best way to do this is by using VPC Network Peering, which allows two VPCs to communicate directly and privately across GCP projects or within the same project. This is a good option because it doesn't require setting up a VPN or additional firewall rules.
In this case, we need to ensure that both GCP projects are in the same GCP organization. If they are not, we need to move them to a common organization.
Once both projects are in the same organization, we can share one of the VPCs with the other project, using VPC Network Peering. Specifically, we would create a VPC network peering connection, where the "peer network" would be the VPC in the other project that we want to connect to.
After that, we can request that the Compute Engine instances in the other project use this shared VPC. This will allow the instances in both VPCs to communicate directly and privately.
Therefore, the correct answer is B. Verify that both projects are in a GCP Organization. Share the VPC from one project and request that the Compute Engine instances in the other project use this shared VPC.
