ITPEC IP April 2019 Question 32

SSID — the name that identifies a wireless LAN.

The SSID (Service Set Identifier) is a name of up to 32 characters set on the access point. Devices show the SSIDs within range, and the user picks one to join; the extended form used in infrastructure networks is also called ESSID.

Answer (b)

Why not others:

• •(a) Bluetooth — a short-range wireless standard for connecting devices such as headsets and keyboards, not the name of a network
• •(c) LTE — a cellular standard for mobile communication (4G)
• •(d) WPA2 — the security standard that authenticates Wi-Fi users and encrypts the traffic; it protects the network the SSID names

Key rule: In Wi-Fi, the SSID says which network, WPA2 or WPA3 says how it is protected; hiding the SSID (stealth) does not make a network secure.
