Question
You have a hub-and-spoke topology. The topology includes multiple on-premises locations that connect to a hub virtual network in Azure via ExpressRoute circuits. You have an Azure Application Gateway named GW1 that provides a single point of ingress from the internet. You plan to migrate the hub-and-spoke topology to Azure Virtual WAN. You need to identify which changes must be applied to the existing topology. The solution must ensure that you maintain a single point of ingress from the internet. Which three changes should you include in the solution? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Options
- AAdd user-defined routes.
- BAdd virtual network peerings.
- CReplace the user-defined routes used by the current topology.
- DCreate virtual network connections.
- ERemove the existing virtual network peerings.
- FRedeploy GW1.

Explanation
Transition connectivity to virtual WAN hub: Step 1. (E) Delete the existing peering connections from Spoke virtual networks to the old customer-managed hub. Access to applications in spoke virtual networks is unavailable until steps 1-3 are complete. Step 2. (D) Connect the spoke virtual networks to the Virtual WAN hub via VNet connections. Step 3. (C) Remove any user-defined routes (UDR) previously used within spoke virtual networks for spoke-to-spoke communications. This path is now enabled by dynamic routing available within the Virtual WAN hub. https://docs.microsoft.com/en-us/azure/virtual-wan/migrate-from-hub-spoke-topology
