Which statement best describes a WLAN?

• A. Wireless Local Area Network connects multiple wireless access points to expand a wireless network.
• B. Wide Area Network connecting across cities.
• C. Metropolitan Area Network spanning a city.
• D. Virtual Private Network across unsecured networks.

Answer: (A)

A WLAN is a local-area network that uses wireless connections to link devices within a limited area, typically using multiple wireless access points to expand coverage. This setup allows devices to roam while staying connected to the network, with the access points providing wireless access and a wired backbone tying them together for the broader network.

The other descriptions describe broader or different concepts: a wide-area network spans large geographic areas like cities or regions, a metropolitan area network covers a city, and a virtual private network is about securing communications across public or shared networks rather than defining a local wireless network.
