Answer: Set up a Cloud VPN gateway in each Shared VPC and peer Cloud VPNs.
The correct answer is C: Set up a Cloud VPN gateway in each Shared VPC and peer Cloud VPNs. VPC peering is not an option here because it does not support peering between VPCs with overlapping subnets. With Cloud VPN, you can establish secure, private network connectivity between the two VPCs without worrying about overlapping subnets, as the VPN can be configured to include only the required IP ranges, which do not overlap. This solution provides the necessary connectivity with minimal re-engineering of the existing infrastructure.

Your company recently acquired another company that also has its infrastructure hosted in Google Cloud. Both companies currently maintain separate Google Cloud organizations. For network connectivity, each organization uses its own Shared Virtual Private Cloud (VPC). However, some of the subnets within these VPCs overlap. To integrate the two businesses, you need to establish private network connectivity between their applications, which are located on non-overlapping subnets. What solution would you choose to achieve this integration with minimal re-engineering of the existing infrastructure?
A
Set up VPC peering and peer each Shared VPC together.
B
Migrate the projects from the acquired company into your company's Google Cloud organization. Re-launch the instances in your company’s Shared VPC.
C
Set up a Cloud VPN gateway in each Shared VPC and peer Cloud VPNs.
D
Configure SSH port forwarding on each application to provide connectivity between applications in the different Shared VPCs.
