A. B. C. D.C
Rapid-PVST (Per VLAN Spanning Tree) is an enhancement to the Spanning Tree Protocol (STP) that allows for faster convergence and better use of available bandwidth. Rapid-PVST introduces a new port state known as the "discarding" state, which is not present in the original STP.
The four port states in Rapid-PVST are:
Discarding state: A port in the discarding state drops all incoming frames and does not forward any outgoing frames. This state is introduced to reduce convergence time by allowing the switch to quickly discard frames that would create a loop.
Learning state: A port in the learning state listens to incoming frames to learn the MAC addresses of connected devices. The port does not forward any outgoing frames during this state.
Forwarding state: A port in the forwarding state passes data frames between devices in the network. The port has learned the location of all devices in the network and knows the best path to forward frames.
Blocking state: A port in the blocking state does not forward any frames and only listens to incoming frames to prevent loops. This state is introduced in the original STP to prevent broadcast storms and loops.
Therefore, the correct answer to the question is C. Discarding state.
