Why each option

MAB stands for MAC Authentication Bypass, which is a feature used in 802.1X environments to authenticate devices that do not support 802.1X, such as printers, IP phones, or surveillance cameras, by using their MAC address.

AMAC Address Binding

MAC Address Binding refers to linking a specific MAC address to an IP address or a port, which is a different concept from authentication.

BMAC Authorization Binding

MAC Authorization Binding is not a recognized term in network access control.

CMAC Authorization Bypass

MAC Authorization Bypass is not the standard or correct acronym; the 'A' stands for Authentication in this context.

DMAC Authentication BypassCorrect

MAC Authentication Bypass (MAB) is a network access control feature that allows devices that do not support the 802.1X authentication protocol to gain network access. Instead of 802.1X, the device's MAC address is used as the credential to authenticate against a RADIUS server (like Cisco ISE).
