Topic 1 Question 118
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?
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.
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.
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.
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
- IP Should not overlap so applying new IP address is the solution

- 正解だと思う選択肢: A
By definition, In cases where you have a VPC subnet and an on-premises route advertisement with overlapping IP ranges, Google Cloud directs egress traffic depending on their IP ranges. With custom route advertisements, you choose which routes Cloud Router advertises to your on-premises router through the Border Gateway Protocol (BGP). Therefore: A - is a permanent solution to the problem which will require time, resources, testing and funding should you decide to change the ip addresses C - is an interim solution that will help to integrate the new company quickly, with view to change the overlaping range at some point in the future (if needed)
The question does not mention any information on the time, cost or complexity, therefore I will go for A
