The ________ feature enables a switch to transition a switchport from blocking to forwarding state quickly by bypassing the listening and learning states

A) PortFast
B) BPDU Guard
C) FastPass
D) Host mode

A
Explanation: A) The Cisco PortFast feature can be enabled on access interfaces that connect to segments that will never contain connections to other switches, which connect back to the switched network. The reason is that PortFast bypasses the STP listening and learning states, which STP uses to determine the ports that should be blocked to prevent switching loops.
