- A
Use Azure Virtual WAN with a secured virtual hub.
Azure Virtual WAN provides a managed hub-and-spoke architecture with automatic routing. A secured virtual hub can integrate NVAs or Azure Firewall, and it handles transitive routing between spokes and on-premises without manual route tables or UDRs.
- B
Use VNet peering with user-defined routes (UDRs) in each spoke and Azure Route Server.
Why wrong: While this is possible, it requires manual configuration and maintenance of UDRs in each spoke and managing BGP with Route Server, increasing administrative overhead.
- C
Create a single large VNet and use network security groups (NSGs) to isolate traffic.
Why wrong: A single VNet does not scale well for cross-region connectivity and does not provide the necessary routing through NVAs without complex configuration.
- D
Use Azure Firewall in the hub VNet and configure forced tunneling via custom routes.
Why wrong: Forced tunneling requires manual route configuration and does not automatically handle transitive routing between spoke VNets; it also requires careful management of routes.
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. A key principle to apply: azure Virtual WAN provides a managed global network architecture.. 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 Azure virtual networks (VNets) in different regions and an on-premises data center connected via ExpressRoute. They need to implement a hub-and-spoke topology where a hub VNet hosts shared network virtual appliances (NVAs) for traffic inspection. All traffic between spokes and between spokes and on-premises must be routed through the hub. The company wants to minimize the administrative overhead of configuring and maintaining routing. Which Azure solution should they implement?
Clue words in this question

Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use Azure Virtual WAN with a secured virtual hub.
Azure Virtual WAN with a secured virtual hub is the correct choice because it provides a managed hub-and-spoke topology with built-in routing, eliminating the need for manual user-defined routes (UDRs) and route tables. The secured virtual hub includes Azure Firewall for traffic inspection, and all inter-spoke and on-premises traffic is automatically routed through the hub via the Virtual WAN routing engine, which uses the Border Gateway Protocol (BGP) to propagate routes dynamically. This minimizes administrative overhead by centralizing routing and security management.
Key principle: Azure Virtual WAN provides a managed global network architecture.

Why it's wrong here
While this is possible, it requires manual configuration and maintenance of UDRs in each spoke and managing BGP with Route Server, increasing administrative overhead.
- ✗
Create a single large VNet and use network security groups (NSGs) to isolate traffic.
Why it's wrong here

Why it's wrong here
Forced tunneling requires manual route configuration and does not automatically handle transitive routing between spoke VNets; it also requires careful management of routes.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose VNet peering with UDRs (Option B) because it is a familiar pattern for hub-and-spoke, but they overlook that Azure Virtual WAN is the managed service designed to eliminate the administrative overhead of manual routing, especially when multiple regions and on-premises connectivity are involved.
Detailed technical explanation
How to think about this question
Azure Virtual WAN uses a dynamic routing infrastructure based on BGP, where each spoke VNet is automatically connected to the hub via VNet connections, and the hub propagates routes to all spokes and on-premises via ExpressRoute. The secured virtual hub integrates Azure Firewall Manager, which applies routing policies (e.g., inter-spoke traffic inspection) without requiring UDRs on spoke subnets. In a real-world scenario, this simplifies adding new spokes because routing updates are handled automatically, whereas manual UDRs would need to be updated for each new spoke or route change.
KKey Concepts to Remember
- Azure Virtual WAN provides a managed global network architecture.
- Virtual WAN virtual hubs support automatic transitive routing between spokes and branches.
- Secured virtual hubs integrate Azure Firewall or third-party NVAs for centralized inspection.
- Virtual WAN reduces administrative overhead for complex routing scenarios.
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
Azure Virtual WAN provides a managed global network architecture.
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.
