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 portatates are blocking,discarding,learing,orforwarding.
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.Because of damaged flash memory, the router will fail the POST.
B.It will attempt to locate the IOS from a TFTP server. If this fails, it will initiate the setup dialog.
C.It will attempt to locate the IOS from a TFTP server. If this fails, it will load a limited IOS from ROM.
D.It will attempt to locate the configuration file from a TFTP server. If this fails, it will initiate the setup dialog.
E.It will attempt to locate the configuration file from a TFTP server. If this fails, it will load a limited configuration from ROM.

A.The denied MAC addresses have already been learned or confgured on another secure interface in the same VLAN.

A.NAT protects network security because privat enetworks 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.
