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?

1. 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. — đáp án hiện tại
2. 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.
3. 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.
4. 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. — đáp án hiện tại
