AZ-305 · Question 53 · Domain 4.4: Design Network Solutions
A global enterprise has branch offices in 20 different countries.
They need to connect all branch offices to Azure, connect the branch offices to each other, and connect them to 100 different Azure Virtual Networks spread across 5 Azure regions. The solution must minimize routing complexity and administrative overhead.
Which Azure networking service should you recommend?

Which Azure networking service should you recommend?
Answer options:
A.
Traditional Hub and Spoke with VNet Peering
B.
Azure Virtual WAN
C.
Azure ExpressRoute Global Reach
D.
Azure Route Server
How to approach this question
Keywords: 'global scale', 'many branches', 'many regions', 'minimize routing complexity'. This is the primary use case for Virtual WAN.
Full Answer
B.Azure Virtual WAN✓ Correct
Azure Virtual WAN
Azure Virtual WAN is designed specifically for large-scale, global connectivity. It simplifies networking by providing a managed hub in each region. You connect your branches (via VPN or ExpressRoute) to the hubs, and connect your VNets to the hubs. Virtual WAN automatically handles the complex transitive routing (branch-to-branch, branch-to-VNet, VNet-to-VNet across regions), drastically reducing administrative overhead.
Common mistakes
Choosing traditional Hub and Spoke. While possible, building a global transit network manually with UDRs and NVAs across 5 regions is highly complex.
