It says on the “Which interface-level” so on the interface you configure pae.
Device> enable
Device# configure terminal
Device(config)# dot1x system-auth-control
Device(config)# aaa new-model
Device(config)# aaa authentication dot1x default group radius
Device(config)# interface fastethernet2/1
Device(config-if)# switchport mode access
Device(config-if)# authentication port-control auto
Device(config-if)# dot1x pae authenticator
Device(config-if)# end
the answer is B.
The dot1x system-auth-control command enables 802.1X authentication on the switch. The no dot1x system-auth-control and default dot1x system-auth-control commands disables 802.1X authentication by removing the dot1x system-auth-control command from running-config.
