Designing and Implementing Microsoft Azure Networking Solutions — Question 101

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.

Answer options

• 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.

Correct answer: C, D, E

Explanation

The correct changes include substituting the user-defined routes (C), establishing virtual network connections (D), and eliminating existing virtual network peerings (E) to adapt to the Azure Virtual WAN architecture. The user-defined routes must be updated to align with the new topology, while virtual network connections are necessary for integration, and existing peerings need to be removed to prevent conflicts. Options A, B, and F do not directly contribute to achieving the necessary configuration for Azure Virtual WAN.
