考题
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.

考题
Which two statements are true when the extended system ID feature is enabled？ （）A、The BID is made up of the bridge priority value（two bytes） and bridge MAC address （six bytes）.B、The BID is made up of the bridge priority （four bits）， the system ID （12 bits）， and a bridge MAC address （48 bits）.C、The BID is made up of the system ID （six bytes） and bridge priority value （two bytes）.D、The system ID value is the VLAN ID （VID）.E、The system ID value is a unique MAC address allocated from a pool of MAC addresses assigned to the switch or module.F、The system ID value is a hex number used to measure the preference of a bridge in the spanning-tree algorithm.
