Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
A company has multiple Azure virtual networks (VNets) in different regions and an on-premises data center. They need to implement a hub-and-spoke topology where the hub VNet hosts shared services like firewalls and DNS. All traffic between spokes, and between spokes and on-premises, must be routed through the hub for inspection. Additionally, spoke VNets must not be able to directly communicate with each other. Which Azure networking solution should they implement to meet these requirements with minimal administrative overhead?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
VNet peering with user-defined routes (UDRs) and network virtual appliances (NVAs)
This can achieve the goal but requires manual configuration of UDRs for each spoke and management of NVAs. It does not inherently prevent direct spoke-to-spoke communication without additional rules, and administrative overhead is high.
B
Best answer
Azure Virtual WAN with routing policies
Azure Virtual WAN provides a centralized hub that connects all spoke VNets and on-premises networks. Routing policies can force traffic through NVAs and block direct spoke-to-spoke routing, all managed with built-in features and minimal overhead.
C
Distractor review
Azure VPN Gateway with route-based VPN
A VPN Gateway only connects on-premises to Azure; it does not create a hub-and-spoke topology among VNets or provide traffic inspection capabilities.
D
Distractor review
Azure ExpressRoute with private peering
ExpressRoute provides dedicated connectivity to on-premises but does not address VNet-to-VNet routing or traffic inspection within Azure.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Virtual WAN with routing policies — Azure Virtual WAN provides a managed hub-and-spoke architecture with built-in routing policies that can enforce traffic inspection via NVAs and prevent direct spoke-to-spoke communication. It also seamlessly integrates ExpressRoute and VPN connections for on-premises connectivity. While VNet peering with UDRs and NVAs can technically work, it requires significant manual configuration and maintenance, making Virtual WAN the preferred solution for large-scale, multi-region topologies with complex routing requirements.
