Answer A,D is correct: A. It can be hidden or broadcast in a WLAN; D. It is at most 32 characters long.. An SSID is the WLAN name advertised or hidden by an access point or controller-based WLAN, and the SSID field can be up to 32 characters. It identifies the wireless network, not a specific access point and not an individual client. It also does not by itself provide secure access; security is supplied by mechanisms such as WPA2, WPA3, 802.1X, PSK, and encryption settings. Cisco CCNA 200-301 v1.1 Network Access includes SSID behavior because WLAN configuration starts with mapping a WLAN profile to an SSID and then applying authentication, encryption, VLAN, and policy settings. A hidden SSID can still be discovered through wireless analysis, so hiding it is not strong security. The correct characteristics are that the SSID can be hidden or broadcast and that it is at most 32 characters long.
