Your company has 200 VPCs across multiple projects and needs centralized enforcement of hub‑and‑spoke routing, path control and on‑prem route distribution. Which Google Cloud product is most appropriate?

Network Connectivity Center (NCC) is the most appropriate solution because it is designed for large-scale network connectivity, offering a hub-and-spoke model that centralizes routing, path control, and on-premises route distribution across many VPCs and projects. This directly addresses the requirement for centralized enforcement and managing 200 VPCs. VPC peering with automated transitive routing is not a native Google Cloud feature; VPC peering is non-transitive, meaning peered networks cannot route traffic to other peered networks through an intermediate VPC. Cloud DNS with conditional forwarding is for name resolution, not network routing or connectivity enforcement. Cloud IAM policies control access to resources, not network topology or routing paths.
