Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has multiple Azure virtual networks (VNets) in different regions connected via VNet peering. They also have an on-premises data center connected to Azure via ExpressRoute. They need to provide internet-bound traffic from all Azure VNets through a single, centralized network virtual appliance (NVA) in the hub VNet for security inspection. They also need to ensure that traffic between VNets and on-premises is routed optimally without going through the internet. Which Azure solution should they implement?
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
Implement VNet peering with user-defined routes (UDRs) to force traffic through the NVA
While possible, this becomes complex with many VNets and does not provide transitive routing; each peering requires separate UDRs.
B
Distractor review
Use Azure Firewall in each VNet to inspect traffic locally
This violates the requirement for centralized inspection and increases cost and management overhead.
C
Best answer
Deploy an Azure Virtual WAN with a secured hub (Azure Firewall) and route traffic through it
Virtual WAN provides automatic transitive routing, centralized security, and integrates with ExpressRoute, meeting all requirements.
D
Distractor review
Use Azure Route Server to propagate routes to all VNets
Route Server exchanges routes but does not provide centralized security inspection or traffic forcing.
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: Deploy an Azure Virtual WAN with a secured hub (Azure Firewall) and route traffic through it — Azure Virtual WAN with a secured hub provides a centralized routing and security solution. It connects VNets and on-premises via ExpressRoute, and can route internet traffic through a firewall (NVA or Azure Firewall) in the hub. This scales better than manual UDRs across multiple peerings. VNet peering with UDRs can work but requires complex management and does not provide transit automatically.
