Designing and planning a cloud solution architecture

Your company has recently acquired another company, and you have been asked to integrate its existing Google Cloud environment with your company’s data center. During the investigation, you find that some RFC 1918 IP ranges used in the acquired company’s Virtual Private Cloud (VPC) overlap with IP space in your data center. What should you do to enable connectivity and ensure that no routing conflicts occur when the connection is established?

  • A Create a Cloud VPN connection from the new VPC to the data center, create a Cloud Router, and apply new IP addresses so there is no overlapping IP space.
  • B Create a Cloud VPN connection from the new VPC to the data center, and create a Cloud NAT instance to perform NAT on the overlapping IP space.
  • C Create a Cloud VPN connection from the new VPC to the data center, create a Cloud Router, and apply a custom route advertisement to block the overlapping IP space.
  • D Create a Cloud VPN connection from the new VPC to the data center, and apply a firewall rule that blocks the overlapping IP space.
Explanation

Hybrid connectivity requires non-overlapping VPC and on-premises IP address spaces for traffic to route correctly. A Cloud VPN with Cloud Router provides the connectivity and dynamic route exchange, while assigning new, non-overlapping VPC addresses removes the route ambiguity. Blocking advertisements or traffic does not make the overlapping destinations uniquely routable.
