Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company has Azure virtual networks (VNets) in three different Azure regions (West US, East US, and West Europe). They also have an on-premises data center connected to the East US region via ExpressRoute. They need to connect all VNets to each other and to the on-premises network. The solution must support transitive routing between all sites and provide centralized management of connectivity and routing policies. Which Azure service should they use?
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
VNet peering provides connectivity between two VNets but is not transitive. It would require a full mesh of peerings to connect all VNets, and it does not natively connect to on-premises networks or provide centralized management.
B
Best answer
Azure Virtual WAN
Azure Virtual WAN provides a hub-and-spoke architecture with built-in transitive routing between VNets and on-premises sites via ExpressRoute or VPN. It offers centralized management of connectivity, routing, and security policies.
C
Distractor review
VPN Gateway
VPN Gateway can connect VNets to on-premises via IPsec, but transitive routing between multiple VNets requires additional VPN Gateways and complex configuration. It does not provide centralized management for multiple regions.
D
Distractor review
ExpressRoute Direct
ExpressRoute Direct is a physical port provisioning option for ExpressRoute. It does not directly provide transitive connectivity between VNets or centralized routing management; it is a connectivity layer.
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 — Azure Virtual WAN is designed to provide transitive connectivity between VNets and on-premises sites (via ExpressRoute or VPN) using a hub-and-spoke architecture. It offers centralized management through the Virtual WAN hub and supports routing policies. VNet peering does not provide transitive routing (non-transitive peerings). VPN Gateway requires manual configuration for transitive routing. ExpressRoute Direct is a physical connection option, not a connectivity service.
