- A
Azure Virtual Network
Why wrong: Azure Virtual Network provides isolated networks but requires manual peering and routing configuration for multi-site connectivity. It is not a managed solution for branch offices.
- B
Azure Virtual WAN
Virtual WAN offers a scalable, managed hub that connects branch offices, Azure VNets, and on-premises resources with automatic routing and integration with ExpressRoute/S2S VPN.
- C
Azure ExpressRoute
Why wrong: ExpressRoute provides a private dedicated connection to Azure but does not itself support branch-to-branch connectivity or automatic routing.
- D
Azure VPN Gateway
Why wrong: VPN Gateway enables site-to-site VPN connections but requires manual setup for multiple branches and does not provide an automated hub architecture.
Quick Answer
The answer is Azure Virtual WAN, the correct choice for managed branch office connectivity because it consolidates VPN, ExpressRoute, and branch links into a single hub-and-spoke architecture with automatic routing and any-to-any connectivity. This service eliminates the complexity of managing individual connections by natively integrating with ExpressRoute and VPN gateways, providing a scalable solution that simplifies network architecture across multiple branch offices. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this question tests your ability to distinguish between Azure Virtual WAN and alternatives like a traditional hub-and-spoke topology with separate VPN gateways—a common trap is choosing a manual configuration that lacks automatic routing and centralized management. Remember that Azure Virtual WAN is the only fully managed service that aggregates all connectivity types into one fabric, so think “WAN = One WAN to rule them all” for a quick memory tip.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has multiple branch offices and needs to connect them to Azure and to each other using a scalable, managed solution that simplifies network architecture. The solution should support automatic routing and integration with ExpressRoute and VPN. Which Azure service should they use?

Correct answer & explanation
Azure Virtual WAN
Azure Virtual WAN is a managed networking service that aggregates branch, VPN, and ExpressRoute connectivity into a single hub-and-spoke architecture. It automatically handles routing between branches and Azure, supports any-to-any connectivity, and integrates natively with ExpressRoute and VPN gateways, making it the correct choice for a scalable, managed solution that simplifies network architecture.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Virtual WAN with Azure Virtual Network, thinking that a simple VNet with VPN gateways can scale to interconnect multiple branches, but they overlook the managed, automatic routing and aggregation capabilities that Virtual WAN provides for multi-site topologies.
Detailed technical explanation
How to think about this question
Azure Virtual WAN uses a hub-and-spoke model where each region has a virtual hub that acts as a central routing point, leveraging BGP for automatic route propagation between all connected sites (VPN, ExpressRoute, and point-to-site). Under the hood, it manages the underlying gateways and routing tables, enabling any-to-any connectivity without manual route table entries, and supports features like Global Reach for ExpressRoute circuits to connect branches across regions. In a real-world scenario, a company with 50 branch offices can deploy a single Virtual WAN hub per region, connect each branch via VPN or ExpressRoute, and automatically achieve full mesh connectivity without configuring individual tunnels or routes.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
