B -
A CSU/DSU converts analog signals from a router to a phone line; a modem converts digital signals from a router to a leased line.
C -
A CSU/DSU converts digital signals from a router to a phone line; a modem converts analog signals from a router to a phone line.

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.

D -
Verify that the encapsulation is set to Frame Relay.

B -
The client's IP address is on the wrong subnet.
C -
