A. VACL
B. 802.1x
C. Private VLAN
D. port security
Correct Answer: B

802.1x requires AAA to be configured on the switch. 802.1x uses AAA authentication to control access to the port.
The overall steps required to configure a switch for 802.1x are:
– Enable AAA on the switch.
– Define the external RADIUS server(s) and the key to be used for encryption.
– Define the authentication method.
– Enable 802.1x on the switch.
– Configure each switch port that will use 802.1x.
– Optionally allow multiple hosts on the switch port.
