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.

C.Dynamic NAT facilitates connections from the outside of the network.
D.NAT facilitates end-to-end communication when IPsec is enable.
E.NAT eliminates the need to re-address all host that require extemal access.
F.NAT conserves addresses through host MAC-level multiplexing.
