Question

Your organization has over 250 autonomous business units that currently operate in a decentralized manner. Due to the organization's maturity, there is limited routable private IP address space, which is insufficient to accommodate all of the necessary workloads. You need to create a cloud-first network design that uses the same IP address space across business unit workloads where possible. These business units require communication between units, and access to their on-premises data center. What should you do?

Options

  • ACreate a hub and spoke model that incorporates VPC Network Peering with hybrid connectivity
  • BCreate a Network Connectivity Center design that incorporates Private NAT to facilitate
  • CCreate a Network Connectivity Center design that incorporates Private Service Connect to
  • DCreate a hub and spoke design that incorporates a centralized network virtual appliance (NVA) in

Explanation

Using Network Connectivity Center (NCC) with Private NAT allows overlapping IP address spaces across business units while ensuring communication between VPC spokes. Private NAT translates overlapping IP ranges to non-conflicting ranges, enabling seamless inter-VPC communication. Additionally, a Routing VPC centralizes dynamic route exchanges with the on- premises environment through Cloud Router, ensuring scalable and efficient hybrid connectivity.
