Actual exam question from Microsoft's AZ-700
Question #: 20
Topic #: 2
[All AZ-700 Questions]

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.

  • A. Add user-defined routes.
  • B. Add virtual network peerings.
  • C. Replace the user-defined routes used by the current topology.
  • D. Create virtual network connections.
  • E. Remove the existing virtual network peerings.
  • F. Redeploy GW1.

The given answers are correct and in correct sequence. First you need to remove existing VNET peering (E) then add VNET connections from VWAN Hub to same spoke VNETs (D) and later removed any existing UDRs you defined earlier. (C). There is no need to reploy App Gateway. Since it is VWAN there will be Vnet connection, no VNET peering.

There is no new UDRs required as it will be replaced by VWAN Hub Dynamic Routing.

The answers are correct. They're specifically listed order on this page: https://learn.microsoft.com/en-us/azure/virtual-wan/migrate-from-hub-spoke-topology#step-5-transition-connectivity-to-virtual-wan-hub a. 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 a-c are complete. b. Connect the spoke virtual networks to the Virtual WAN hub via VNet connections. 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.

To migrate your hub-and-spoke topology to Azure Virtual WAN while maintaining a single point of ingress from the internet: Add virtual network peerings (B): This will help connect your existing virtual networks to the Virtual WAN hub, ensuring seamless communication between them. Create virtual network connections (D): This is necessary to establish connectivity between your virtual networks and the Virtual WAN hub. Remove the existing virtual network peerings (E): Since Virtual WAN will handle the connectivity, the existing peerings are no longer needed and should be removed to avoid conflicts.
