AZ-305 · Question 48 · Domain 4.4: Network Solutions
A multinational corporation is redesigning its global network architecture.
They have 50 branch offices worldwide and 3 major on-premises data centers. They use Azure heavily, with 100+ Virtual Networks spread across 4 Azure regions.
They require a networking solution that:
- Provides any-to-any connectivity (branch-to-branch, branch-to-Azure, Azure-to-Azure).
- Automates the routing between all these endpoints.
- Minimizes the operational overhead of managing complex route tables and peering connections.
Which network architecture should you recommend?

Which network architecture should you recommend?
Answer options:
A.
Traditional Hub-and-Spoke with VNet Peering
B.
Azure Virtual WAN
C.
Azure ExpressRoute with Global Reach
D.
Azure Front Door
How to approach this question
Look for keywords: 'any-to-any connectivity', 'global', 'many branches/VNets', and 'minimize routing overhead'.
Full Answer
B.Azure Virtual WAN✓ Correct
Azure Virtual WAN is a networking service that brings many networking, security, and routing functionalities together to provide a single operational interface. It is specifically designed for large-scale, global architectures requiring any-to-any connectivity (branch-to-branch, branch-to-VNet, VNet-to-VNet). It automates the complex routing that would otherwise require hundreds of User Defined Routes (UDRs) and peering connections in a traditional hub-and-spoke model.
Common mistakes
Choosing Traditional Hub-and-Spoke. While valid for smaller setups, the operational overhead of managing UDRs for 100+ VNets across 4 regions makes Virtual WAN the architectural best practice.
