Which three statements about 802.1X are true? (Choose three)

A.
It is IEEE standard

B.
It can allow and deny port access based on device identity

C.
It works only with wired device

D.
It can allow and deny port access based on user identity

Explanation:
IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an
authentication mechanism to devices wishing to attach to a LAN or WLAN.
802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server.

The supplicant is a client device (such as a laptop) that wishes to attach to the LAN/WLAN. The term ‘supplicant’ is also used interchangeably to refer to the
software running on the client that provides credentials to the authenticator.
The authenticator is a network device, such as an Ethernet switch or wireless access point; and the authentication server is typically a host running software
supporting the RADIUS and EAP protocols. In some cases, the authentication server software may be running on the authenticator hardware.
