What is a mesh topology advantage?

• A. Simple in principle and low delay
• B. High maintenance
• C. High cost
• D. Low bandwidth

Answer: (A)

A mesh topology is built by interconnecting nodes so there are multiple routes between any two points. The standout advantage is robustness: if one link or node fails, data can still find another path to the destination, keeping communication alive. This redundancy also helps keep delays low, because traffic can be routed along the shortest or least congested path available, rather than being forced through a single bottleneck. The basic idea—connecting nodes in a way that provides alternate routes—is simple to grasp, and in practice this setup can maintain connectivity and performance even under failures.

The other statements reflect tradeoffs rather than advantages. More interconnections typically mean higher maintenance and cost, and bandwidth is not inherently limited in a mesh; with proper design, it can support strong bandwidth, though the exact performance depends on the size and layout of the network.
