What is a characteristic of an SSID in wireless networks?

Answer options

• A. allows easy file sharing between endpoints
• B. identifies a wireless network
• C. eliminates network piggybacking
• D. requires the use of PoE for functionality

Correct answer: B

Explanation

The correct answer is B because an SSID (Service Set Identifier) is a unique name that identifies a wireless network, allowing devices to connect to the correct network. Options A, C, and D are incorrect as they do not accurately describe the function of an SSID; they refer to different aspects of networking or technology.
