Which port state is introduced by Rapid-PVST?
A.
learning
B.

discarding
D.

Explanation:
PVST+ is based on IEEE802.1D Spanning Tree Protocol (STP). But PVST+ has
only 3 port states (discarding, learning and forwarding) while STP has 5 port states (blocking,
listening, learning, forwarding and disabled). So discarding is a new port state in PVST+.
