Fortinet Exam NSE7_LED-7.0 Topic 1 Question 3 Discussion

According to the exhibit, the User-Name attribute in the RADIUS Access-Request packet contains the client MAC address of 00:0c:29:6a:2b:3d. This indicates that FortiSwitch is authenticating the client using MAC authentication bypass (MAB), which is a method of authenticating devices that do not support 802.1X by using their MAC address as the username and password. Therefore, option B is true because it explains why the User-Name attribute contains the client MAC address. Option A is false because AD machine authentication uses a computer account name and password, not a MAC address. Option C is false because user authentication uses a user name and password, not a MAC address. Option D is false because FortiSwitch is sending a RADIUS Access-Request message to FortiAuthenticator, not a RADIUS accounting message.
