What type of network enables wireless devices to move around within a building while maintaining network connectivity?

• A. Wireless Local Area Network (WLAN)
• B. Local Area Network (LAN)
• C. Virtual Private Network (VPN)
• D. Campus Area Network (CAN)

Answer: (A)

The main idea here is wireless mobility within a local area. A Wireless Local Area Network provides wireless connectivity to devices inside a building or a small area using access points that are connected to a wired backbone. As you move around, your device can switch from one access point to another, maintaining the connection without needing cables. That roaming capability within a localized space is what enables devices to stay connected while moving.

The other options don’t fit as well. A Local Area Network is typically thought of as the broader local network, often wired, and doesn’t inherently emphasize wireless roaming. A Virtual Private Network is about secure remote access over the internet, not about staying connected while moving inside a building. A Campus Area Network covers multiple buildings over a larger area, not specifically the in-building mobility aspect.
