Exam Professional Cloud Architect topic 1 question 188 discussion

Actual exam question from Google's Professional Cloud Architect
Question #: 188
Topic #: 1
[All Professional Cloud Architect Questions]

Your company and one of its partners each have a Google Cloud project in separate organizations. Your company's project (prj-a) runs in Virtual Private Cloud
(vpc-a). The partner's project (prj-b) runs in vpc-b. There are two instances running on vpc-a and one instance running on vpc-b. Subnets defined in both VPCs are not overlapping. You need to ensure that all instances communicate with each other via internal IPs, minimizing latency and maximizing throughput. What should you do?

  • A. Set up a network peering between vpc-a and vpc-b.
  • B. Set up a VPN between vpc-a and vpc-b using Cloud VPN.
  • C. Configure IAP TCP forwarding on the instance in vpc-b, and then launch the following gcloud command from one of the instances in vpc-a gcloud: gcloud compute start-iap-tunnel INSTANCE_NAME_IN_VPC_8 22 \ --local-host-port=localhost:22
  • D. 1. Create an additional instance in vpc-a. 2. Create an additional instance in vpc-b. 3. Install OpenVPN in newly created instances. 4. Configure a VPN tunnel between vpc-a and vpc-b with the help of OpenVPN.

VPC peering: https://cloud.google.com/vpc/docs/vpc-peering Peered VPC networks can be in the same project, different projects of the same organization, or different projects of different organizations. IPv4 subnet routes in peered VPC networks can't overlap

Selected Answer: A
Since it's mentioned that the subnets do not overlap, A is the best way to go. If the subnets overlapped, you would go with B. https://cloud.google.com/vpc/docs/vpc-peering#interaction-subnet-subnet
