Answer: Configure a single VPC with 2 subnets having the different CIDR range hosted in the same region
The correct answer is **C** because the VMs need to communicate using private IPs, which requires them to be hosted in the same VPC. The subnets can be in any region but must have non-overlapping CIDR ranges to avoid conflicts. - **Option A** is incorrect because overlapping CIDR ranges are not allowed within the same VPC. - **Options B & D** are incorrect because VMs in subnets across different VPCs cannot communicate with each other using private IPs without additional configuration like VPC peering or VPN. Refer to the GCP documentation on VPC requirements for more details on intra-VPC communication and firewall rules necessary for instance communication within the same network.
