Correct Answer
B. A crossover Category 5e patch cable and a RG-6 co-axial cableExplanation
You can connect a cable modem to a computer via a switch. However, the cable modem's Ethernet connection is physically and electronically the same as a medium dependent interface-crossover (MDI-X) port on the switch, therefore you need a crossover cable to connect the two. You would also need a RG-6 cable that the cable modem uses to receive its signals. This cable connects to the wall socket, which feeds into the cable from the cable provider.Rate this question:
