Which statement best describes 802.11 as noted?

• A. It is primarily used for wired networks
• B. Widely used in wireless communication
• C. It has no security concerns
• D. It requires fiber backbones

Answer: (B)

802.11 defines wireless local-area networking, enabling devices to connect over the air to an access point. This makes it the standard basis for Wi‑Fi, so it’s widely used for wireless communication in homes, offices, and public spaces. The other statements don’t fit: it isn’t primarily for wired networking, the wireless medium introduces security concerns that have led to protections like WPA/WPA2/WPA3, and it doesn’t require a fiber backbone—the wireless portion sits atop whatever transport the network uses, which can be copper, fiber, or other media.
