Answer: Configure a single VPC with two subnets. Each subnet should have a different CIDR range and can be hosted in any region, as long as the ranges do not overlap.
The correct answer is **B** because the VMs need to communicate using private IPs, which requires them to be within the same VPC. Subnets can be in any region but must have non-overlapping CIDR ranges to avoid conflicts. This setup allows for internal communication without additional routes. - **Option A** is incorrect because overlapping CIDR ranges within the same VPC are not allowed. - **Options C & D** are incorrect because VMs in different VPCs cannot communicate using private IPs without additional configuration, such as VPC peering or VPN.
