Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A company has multiple virtual networks in different Azure regions. They need to connect all VNets together securely over the Microsoft backbone. They also need to connect to an on-premises data center via ExpressRoute. The solution should support transitive routing between all connected networks. 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
Azure Virtual Network Peering
VNet peering is not transitive; each pair must be peered separately.
B
Distractor review
Azure VPN Gateway
VPN Gateway can connect VNets but requires manual BGP configuration and does not provide transitive routing out of the box.
C
Best answer
Azure Virtual WAN
Virtual WAN provides a hub that connects multiple VNets and on-premises sites with automatic transitive routing.
D
Distractor review
Azure ExpressRoute Gateway
ExpressRoute Gateway connects a single VNet to ExpressRoute; it does not connect multiple VNets.
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 provides a hub-and-spoke architecture with built-in transit routing between all connected VNets and branches, including ExpressRoute. VNet peering does not support transitive routing. VPN Gateway requires manual configuration for transit. ExpressRoute Gateway only connects a single VNet to ExpressRoute.
