    You have purchased a new cable modem which was supplied without cables.  You need to connect the cable modem to a 100Base-T switch.  Which of the following cables would you require?

    • A straight-through Category 5e patch cable and a serial cable

    • A crossover Category 5e patch cable and a RG-6 co-axial cable

    • A straight-through Category 5e patch cable and a RG-6 co-axial cable

    • A crossover Category 5e patch cable and a serial cable

    Explanation
    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.

    Correct Answer
    A. A crossover Category 5e patch cable
    Explanation
    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 cable modem to the switch, and not a straight-through cable.

    Rate this question:

    • While 10GBase-SR has a greater transmission speed than 1000Base-SX, 10GBase-SR has a shorter maximum transmission distance than 1000Base-SX

    • While 100Base-FX uses multi-mode fiber, it has the same maximum transmission distance than 1000Base-LX with single-mode fiber has

    Correct Answer
    A. While 1000Base-LX can use either multi-mode or single-mode fiber, it has a longer transmission distance when multi-mode fiber is used
    Explanation
