A medium-sized enterprise has some devices that are 802.1X capable and some that are not. Any
device that fails authentication must be provided limited access through a VLAN called
NONAUTH.
How do you provide this access?
A.
Configure NONAUTH VLAN as the guest VLAN.
B.
Configure NONAUTH VLAN as the server-reject VLAN.
C.
Configure NONAUTH VLAN as the guest VLAN and the server-reject VLAN.
D.
Configure a separate VLAN for each type of user: 802.1X and non-802.1X.
b, since the question is about failed auth (not about where to put non-802.1x devices)
C, since auth fail may be because of wrong credentials or no 802.1X response from host.
Therefore, we need to cfg guest vlan (no 802.1x response) and server-reject (wrong creds).
