Server1 (Windows Server) is deployed in West US and HostPool1 is deployed in East US. To ensure all traffic between HostPool1 and Server1 is routed across the Microsoft backbone, which should you use?

Virtual network peering connects two Azure virtual networks, allowing resources in each VNet to communicate directly using private IP addresses. This traffic remains entirely within the Microsoft backbone network, ensuring low latency and high bandwidth, which is crucial for optimal performance between a host pool and a backend server. Service endpoints secure and optimize traffic to Azure services like Storage or SQL Database, but they don't connect two separate virtual networks. Routing tables manage traffic flow within or between subnets and VNets based on defined rules, but they don't inherently guarantee traffic stays on the Microsoft backbone for cross-region VNet communication in the way peering does. Azure Traffic Manager is a DNS-based traffic load balancer that distributes user traffic to different service endpoints, primarily for high availability and responsiveness, not for ensuring backbone routing between VNets.
