C.Routing updates are automatically sent to neighbors.
D.Route summarization iscompued automatically by the router.
E.Routing traffic load is reduced when used in stub network links
F.An efficient algorithm is used to build routing tables，using automatic updates.
G.Routing tables adapt automatically to topology changes.

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.

A.IronPort
B.Cisco NAC
C.SAN
D.CSA

A.NAT protects network security because private networks are not advertised.
B.NAT accelerates the routing process because no modifications are made on the packets.
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.

B.The router at 208.149.23.130 is a secondary DR in case the primary fails.
C.Two router IDs have the same OSPF priority and are therefore tied for DR election
