Google Cloud Professional Cloud Architect — Question 130

Your company has just acquired another company, and you have been asked to integrate their existing Google Cloud environment into your company's data center. Upon investigation, you discover that some of the RFC 1918 IP ranges being used in the new company's Virtual Private Cloud (VPC) overlap with your data center IP space. What should you do to enable connectivity and make sure that there are no routing conflicts when connectivity is established?

Answer options

• 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.

Correct answer: A

Explanation

The correct answer is A because creating a Cloud VPN connection, along with a Cloud Router and reassigning IP addresses, ensures that there will be no overlapping IP space, allowing for seamless connectivity. Options B, C, and D do not resolve the root issue of overlapping IP addresses, which could lead to routing conflicts or connectivity problems.
