On the network shown in the following figure, 802.1X authentication is deployed on GE0/0/1 of SW2. Which of the following statements are correct?
A.
When MAC address-based access control is used, 802.1X clients A and B must be authenticated separately before they can obtain corresponding network access permissions.
B.
When interface-based access control is used, 802.1X client B can use network resources without being authenticated if 802.1X client A is successfully authenticated.
C.
Assume that SW2 uses MAC address-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will still have the corresponding network access permissions because the interface status remains unchanged.
D.
Assume that SW2 uses the interface-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will lose the corresponding network access permissions.
