How would Cisco ISE handle authentication for your printer that does not have a supplicant?
Correct Answer: C
Explanation Cisco ISE can handle authentication for printers that do not have a supplicant using MAB (MAC Authentication Bypass). MAB is a method of authenticating devices based on their MAC address. MAB is useful for devices that do not support 802.1X or other authentication protocols, such as printers, cameras, or IoT devices. MAB works as follows: The device sends an Ethernet frame with its MAC address as the source address. The switch sends a RADIUS Access-Request message to ISE with the MAC address as the username and password. ISE checks the MAC address against a database of known devices or an identity source sequence. If the MAC address is found and authorized, ISE sends a RADIUS Access-Accept message to the switch with the appropriate authorization profile. The switch applies the authorization profile to the device and grants it access to the network. MAB is less secure than 802.1X, as MAC addresses can be spoofed or cloned. Therefore, MAB should be used with caution and combined with other security measures, such as profiling, posture, or endpoint protection. MAB should also be restricted to specific ports or VLANs that are isolated from the rest of the network.
