- A
Azure Virtual WAN
Azure Virtual WAN provides a hub-and-spoke architecture across regions, automatically routes traffic, supports VPN and ExpressRoute, and simplifies management of multiple branch connections.
- B
Azure VPN Gateway (site-to-site) with BGP
Why wrong: Azure VPN Gateway can connect multiple on-premises sites, but each site requires a separate connection object and BGP configuration. It does not provide transitive connectivity between branches automatically.
- C
Azure ExpressRoute with Microsoft peering
Why wrong: ExpressRoute provides private connectivity from on-premises to Azure but does not natively connect multiple on-premises sites to each other through Azure without additional configuration.
- D
Azure Virtual Network peering
Why wrong: VNet peering connects Azure VNets but does not provide connectivity to on-premises networks. It also does not manage branch connectivity.
Quick Answer
Azure Virtual WAN is the correct choice because it delivers a single, centrally managed hub-and-spoke architecture that seamlessly connects headquarters, branch offices, and Azure for multi-site hybrid connectivity. It automatically handles routing, including BGP, and supports both VPN and ExpressRoute connections with high bandwidth, eliminating the need to manually configure multiple tunnels or complex routing tables. On the AZ-305 exam, this scenario tests your ability to select a service that consolidates disparate site-to-site traffic under one management plane, often appearing as a contrast to manually configured VPN gateways or individual ExpressRoute circuits. A common trap is choosing Azure VPN Gateway alone, which lacks the unified routing and scalability for global multi-site topologies. Remember the mnemonic “WAN = One Hub to Rule Them All” — if the requirement is a single pane of glass for all branch and Azure connectivity, think Virtual WAN first.
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 headquarters and multiple branch offices worldwide, each with its own on-premises network. They want to connect all these sites to Azure and to each other over a single, centrally managed solution. They need high bandwidth connectivity for site-to-site traffic, support for both VPN and ExpressRoute connections, and automatic routing management without the complexity of configuring multiple VPN tunnels or BGP manually. Which Azure service should they use?

Correct answer & explanation
Azure Virtual WAN
Azure Virtual WAN is the correct choice because it provides a single, centrally managed hub-and-spoke architecture that connects branch offices, headquarters, and Azure over a unified network. It supports both VPN and ExpressRoute connections, automatically manages routing (including BGP) without manual configuration of multiple tunnels, and offers high bandwidth for site-to-site traffic.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Azure VPN Gateway (site-to-site) with BGP
- ✗
Azure ExpressRoute with Microsoft peering
Why it's wrong here
ExpressRoute provides private connectivity from on-premises to Azure but does not natively connect multiple on-premises sites to each other through Azure without additional configuration.
- ✗
Azure Virtual Network peering
Why it's wrong here
VNet peering connects Azure VNets but does not provide connectivity to on-premises networks. It also does not manage branch connectivity.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Virtual WAN with a simple VPN gateway or ExpressRoute, not realizing that Virtual WAN is a managed overlay that combines both connectivity types with automatic routing, while the other options require manual configuration for multi-site scenarios.
Detailed technical explanation
How to think about this question
Azure Virtual WAN uses a hub-and-spoke topology where each region has a virtual hub that acts as a transit router, automatically propagating routes via BGP between all connected sites (VPN, ExpressRoute, and point-to-site). It leverages the Microsoft backbone for optimal routing, and supports SD-WAN integration for automated configuration of branch devices, reducing operational overhead compared to manually managing individual VPN tunnels or BGP sessions.
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.
