Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has headquarters and multiple branch offices worldwide, each with its own on-premises network. They want to connect all these sites to Azure and to each other over a single, centrally managed solution. They need high bandwidth connectivity for site-to-site traffic, support for both VPN and ExpressRoute connections, and automatic routing management without the complexity of configuring multiple VPN tunnels or BGP manually. 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
Best answer
Azure Virtual WAN
Azure Virtual WAN provides a hub-and-spoke architecture across regions, automatically routes traffic, supports VPN and ExpressRoute, and simplifies management of multiple branch connections.
B
Distractor review
Azure VPN Gateway (site-to-site) with BGP
Azure VPN Gateway can connect multiple on-premises sites, but each site requires a separate connection object and BGP configuration. It does not provide transitive connectivity between branches automatically.
C
Distractor review
Azure ExpressRoute with Microsoft peering
ExpressRoute provides private connectivity from on-premises to Azure but does not natively connect multiple on-premises sites to each other through Azure without additional configuration.
D
Distractor review
Azure Virtual Network peering
VNet peering connects Azure VNets but does not provide connectivity to on-premises networks. It also does not manage branch connectivity.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Virtual WAN — Azure Virtual WAN is a networking service that simplifies connectivity across branch offices, headquarters, and Azure. It supports both VPN and ExpressRoute connections, provides automatic routing and transitive connectivity between all sites, and is centrally managed. Azure VPN Gateway alone requires separate configurations for each site-to-site connection. ExpressRoute with Microsoft peering provides connectivity but not automatic routing between branches. Multiple VNet peering does not connect to on-premises sites natively.
