Which statement best describes a WMN?

• A. Wireless Mesh Network connects multiple wireless access points to expand the wireless network.
• B. Wireless Local Area Network connects devices in a building.
• C. Metropolitan Area Network spanning a city.
• D. Virtual Private Network secures connections over the internet.

Answer: (A)

A wireless mesh network is about a collection of wireless nodes that all work together to extend wireless coverage by relaying data through multiple hops. In a WMN, each node can act as both a host and a router, forwarding traffic for others. This creates a flexible, self-healing network where adding more access points expands reach, and there are often multiple paths for data to travel, improving reliability. The statement describes this idea directly: connecting multiple wireless access points to broaden the wireless network.

This differs from a standard wireless local area network, which typically covers a single building or a smaller area with APs connected to a central controller but not necessarily designed to route traffic through a mesh of peer APs. A metropolitan area network implies city-wide connectivity often using various technologies beyond wireless mesh, and a virtual private network focuses on secure tunnels over the internet rather than the shared wireless infrastructure itself.
