Which statement describes an SSID in wireless networks?

An SSID (Service Set Identifier) is the name of a wireless network. It allows users to identify and connect to a specific Wi-Fi network among others in the vicinity. For example, when you see a list of available Wi-Fi networks on your device, you are seeing their SSIDs. "Enables easy file sharing between endpoints" is incorrect; file sharing is a network service, not a function of the SSID itself. "Eliminates network piggybacking" is also incorrect; while security measures like strong passwords help prevent unauthorized access, the SSID alone does not eliminate piggybacking. "Requires Power over Ethernet to function" is incorrect; PoE powers access points, but the SSID is a logical identifier and does not directly require PoE.
