Answer: Create 1 VPC with 2 regional subnets. Deploy workloads in these subnets and have them communicate using private RFC1918 IP addresses.
Option D is the most efficient and cost-effective solution for the scenario described. It leverages Google's internal network for communication between workloads in different regions using private RFC1918 IP addresses, avoiding the costs and latency associated with VPN gateways or public IP addresses. This approach ensures minimal cost and optimal network performance for end users located near us-east1 and europe-west1.

How should you design a network topology to enable efficient and cost-effective communication between workloads for end users located near us-east1 and europe-west1?
A
Create 2 VPCs, each with their own regions and individual subnets. Create 2 VPN gateways to establish connectivity between these regions.
B
Create 2 VPCs, each with their own region and individual subnets. Use external IP addresses on the instances to establish connectivity between these regions.
C
Create 1 VPC with 2 regional subnets. Create a global load balancer to establish connectivity between the regions.
D
Create 1 VPC with 2 regional subnets. Deploy workloads in these subnets and have them communicate using private RFC1918 IP addresses.
