Question

Which port state will switch ports immediately transition to when configured for PortFast?

1) Blocking
2) Listening
3) Learning
4) Forwarding

Answer 1

Switch ports configured with PortFast transition immediately to the Forwarding state, bypassing the usual STP Listening and Learning states.

Step-by-step explanation:

When a switch port is configured with the PortFast feature, it immediately transitions to the Forwarding state. This behavior is designed to reduce the time it takes for ports associated with end devices, such as computers or printers, to begin sending and receiving data immediately after being connected to the switch.

PortFast bypasses the traditional Spanning Tree Protocol (STP) states of Listening and Learning to expedite the transition to Forwarding, thus allowing immediate communication.
