You have an Azure subscription. The subscription contains a virtual machine named Server1 that runs Windows Server and is deployed to the West US Azure region. You deploy a new Azure Virtual Desktop h

Service endpoints provide secure and direct connectivity to Azure services from a virtual network over the Azure backbone, but they are not used for connecting two separate virtual networks or VMs within them across regions.

Virtual network peering connects two or more Azure virtual networks, allowing traffic between them to flow directly over the Microsoft backbone network using private IP addresses. This provides secure, low-latency communication between resources like HostPool1 and Server1 even when they are located in different Azure regions.

Routing tables (User-Defined Routes) manage traffic flow within or between virtual networks by specifying next-hop IP addresses, but they don't inherently connect virtual networks across regions via the Microsoft backbone without an underlying peering or VPN gateway.

Azure Traffic Manager is a DNS-based traffic load balancer that distributes incoming traffic across different endpoints based on routing methods, primarily for external-facing services, not for routing internal VM-to-VM traffic over the backbone network.
