You have two virtual networks, VNet1 and VNet2. You need to ensure that all traffic between them travels over the Microsoft backbone network. Which feature should you configure?

Peering is the correct feature because it allows you to connect two Azure virtual networks seamlessly, enabling traffic to flow between them privately over the Microsoft backbone network. This ensures low latency and high bandwidth communication without traversing the public internet. A private endpoint is incorrect because it provides private connectivity to Azure services, not between two virtual networks. ExpressRoute is incorrect because it connects your on-premises network to Azure, not two Azure virtual networks. A route table is incorrect because it defines how traffic is routed within or between subnets, but it doesn't establish the underlying connection between two virtual networks; peering does that.
