Question

A network architect is creating a network topology for a global SD-WAN deployment. The business has offices in Asia, Europe, and the United States and makes use of data centers in the United States and Europe. Most traffic between sites must have the lowest latency possible. Which of the following topologies best meets this requirement?

Options

AStar
BSpine-and-leaf
CMesh
DHub-and-spoke

Explanation

A mesh topology creates direct connections between all sites, allowing traffic to take the shortest path between any two locations. For a global deployment where low latency is the top priority, mesh ensures Asia-to-Europe traffic doesn't have to traverse a US hub. Star (A) and Hub-and-spoke (D) are essentially the same concept - all traffic is funneled through a central point, which adds latency for inter-regional communication. Spine-and-leaf (B) is a data center internal architecture, not a WAN topology. Mesh is the correct answer even though it is more expensive, because the requirement explicitly prioritizes lowest latency.
