A network device needs to be installed in the place of the icon labeled Network Device to
accommodate a leased line attachment to the Internet. Which network device and interface
configuration meets the minimum requirements for this installation?

B.
a switch with two Ethernet interfaces
C.
a router with one Ethernet and one serial interface
D.
a switch with one Ethernet and one serial interface
E.
a router with one Ethernet and one modem interface
Explanation:
Only a router can terminate a leased line attachment access circuit, and only a router can connect
two different IP networks. Here, we will need a router with two interfaces, one serial connection for
the line attachment and one Ethernet interface to connect to the switch on the LAN.
