A logistics company runs 40 branch offices spread across three continents. Each branch must reach other branches and several VNets, and the team wants to avoid building and routing hub networks by hand. Which architecture fits best?
Show answer and explanation
Answer: D
Azure Virtual WAN provides managed virtual hubs in each region, and branches connect to those hubs. Transit between branches and virtual networks is handled by the managed fabric, so the team avoids building and routing hub networks manually. A single gateway with peering does not scale well for this kind of global topology.
Why the other options are wrong
- A. One gateway in one region becomes a bottleneck and adds latency for distant branches. Peering each region to it still requires manual routing for transit.
- B. Traffic Manager steers DNS responses to endpoints. It does not connect branch offices or carry traffic between sites and networks.
- C. Azure Bastion provides secure browser-based administrative access to VMs. It is not a branch transit architecture.
