Which statement describes an SSID?

An SSID (Service Set Identifier) is the name given to a wireless local area network (WLAN). It's the name you see when you scan for available Wi-Fi networks. For example, "HomeNetwork" or "GuestWi-Fi" are SSIDs. This name allows devices to identify and connect to a specific wireless network. The other options are incorrect: An SSID can consist of only letters, only numbers, or a combination; there's no strict requirement for both. While security policies are used to prevent unauthorized users, the SSID itself is just the network name, not the policy mechanism. An SSID does not inherently prompt for a login ID; that's a function of the authentication method (e.g., WPA2-PSK, WPA2-Enterprise) used by the WLAN.
