Your on-premises network includes a VPN gateway. In your Azure subscription (resources shown in the table), what should you configure so traffic from VM1 to storage1 stays on the Microsoft backbone?

Service endpoints allow traffic from your virtual network to Azure services like Storage to use the Microsoft backbone network, rather than traversing the public internet. This improves security and routing efficiency. Azure Application Gateway is a Layer 7 load balancer and wouldn't directly impact how VM1 connects to Storage1 over the Microsoft backbone. A Network Security Group (NSG) filters network traffic to/from Azure resources but doesn't dictate the routing path to Azure services. Azure Peering Service is for optimizing connectivity to Microsoft services for customers with large-scale internet peering, not for direct VM-to-service connectivity within Azure.
