Which three statements about RSTP are true?()A. RSTP significantly reduces topology reconverging time after a link failure.B. RSTP expends the STP port roles by adding the alternate and backup roles.C. RSTP port atates are blocking,discarding,learing,or forwarding.D. RSTP also uses the STP proprsal-agreement sequence.E. RSTP use the same timer-baseed process as STP on point-to-point links.F. RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.
