A.VTP allows routing between VLANs.

B.VTP allows a single switch port to carry information to more than one VLAN.

C.VTP allows physically redundant links while preventing switching loops.

D.VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information.

E.VTP helps to limit configuration errors by keeping VLAN naming consistent across the VTP domain.

F.VTP enhances security by preventing unauthorized hosts from connecting to the VTP domain.

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.
