Which three statements about RSTP are true? (Choose three.)
A.
RSTP significantly reduces topology reconverging time after a link failure.
B.
RSTP expands the STP port roles by adding the alternate and backup roles.
C.
RSTP port states are blocking, discarding, learning, or forwarding.
D.
RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.
E.
RSTP also uses the STP proposal-agreement sequence.
F.
RSTP uses the same timer-based process as STP on point-to-point links.
RSTP is Rapid STP. RSTP works by adding an alternative port and a backup port compared to STP.
RSTP significantly speeds the recalculation of the spanning tree when the network topology changes. RSTP defines the additional port roles of Alternate and Backup and defines port states as discarding, learning, or forwarding.
RSTP enables switch-port configuration so that the ports transition to forwarding directly when the switch reinitializes.
(Under 802.1w:) Designated ports: A port that is attached to the same link-type shared link as another port on the same switch, but the other port is the DP for that segment. The Backup Port is ready to take over if the DP fails. Make the most use of the link type parameter. Rapid transition to the forwarding state for the designated port occurs only if the link type parameter indicates a point-to-point link.
