Why each option
An SSID, by default, is broadcast through beacon signals by access points to advertise the presence of a wireless network.
An SSID does not intercept data threats; that function is performed by security devices like firewalls or intrusion detection/prevention systems.
Encoding connections (encryption) is a security measure applied to the data payload, not a characteristic of the SSID itself.
By default, wireless access points periodically broadcast beacon frames, which contain the SSID (Service Set Identifier) of the wireless network, allowing client devices to discover and identify available networks.
An SSID identifies the wireless *network* (WLAN) to which clients connect, not necessarily a single specific access point, as multiple APs can share the same SSID.
