QUESTION 52

Which statement about VLAN operation on Cisco Catalyst switches is true?

QUESTION 54

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.

 

Correct Answer: ABD
