In which Spanning-Tree states does a switch port learn MAC addresses?（）
第1题：
A network administrator must configure 200 switch ports to accept traffic from only the currently attached host devices. What would be the most efficient way to configure MAC-level security on all these ports?（）
A. Visually verify the MAC addresses and then telnet to the switches to enter the switchport-port security mac-address command.
B. Have end users e-mail their MAC addresses. Telnet to the switch to enter the switchport-port security mac-address command.
C. Use the switchport port-security MAC address sticky command on all the switch ports that have end devices connected to them.
D. Use show mac-address-table to determine the addresses that are associated with each port and then enter the commands on each switch for MAC address port-security.
第2题：
A.The network administrator can apply port security to dynamic access ports
B.The network administrator can configure static secure or sticky secure mac addresses in the voice vlan.
C.The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.
D.The network administrator can apply port security to EtherChannels.
E.When dynamic mac address learning is enabled on an interface,the switch can learn new addresses,up to the maximum defined.
