You are the administrator of a switch and currently all host-connected ports are configured

states that, in the future, any host-connected port that receives a BPDU should automatically
disable PortFast and begin transmitting BPDUs. Which of the following commands will
support this new requirement?
A.
Switch(config)#spanning-tree portfast bpduguard default
B.
Switch(config-if)#spanning-tree bpduguard enable
C.
Switch(config-if)#spanning-tree bpdufilter enable
D.
Switch(config)#spanning-tree portfast bpdufilter default
