Which port state is introduced by Rapid-PVST?
A.
learning
B.
listening
C.
discarding
D.
forwarding
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+.
Discarding is port state in Rapid PVST+ not in PVST+
The question states Rapid-PVST.
