    You are trying to connect directly into the LAN prot of a Ezonexam router. You want to telnet to the local Cisco router using TCP/IP but cannot create a session.

    What should you do to resolve the problem?

    A. Use a straight-through cable to connect your computer's COM port to the router's console port.

    B. Use a crossover cable to connect your computer's COM port to the router's console port.

    C. Use a straight-through cable to connect your computer's COM port to the router's Ethernet port.

    D. Use a crossover cable to connect your computer's Ethernet port to the router's Ethernet port.

    E. Use a rollover cable to connect your computer's Ethernet port to the router's Ethernet port.

    F. Use a straight-through cable to connect your computer's Ethernet port to the router's Ethernet port.

    G. None of the above


    正确答案：D
    D 解析：Explanation:
    In order to connect directly to a router via telnet, you must connect to the router via one of the LAN ports. When connecting directly to the Ethernet port with a PC without the use of a switch or hub, a crossover cable must be used.

    Incorrect Answers:
    A, B, C. In order to telnet directly into the router via a TCP/IP connection, the COM port of the PC can not be used. The COM port is used for direct terminal emulation programs such as HyperTerminal.

    E. Rollover cables are used for console connections into the router, not for TCP/IP connections.

    F. Straight through cables are used for connections into a switch or hub from the PC. It will not work for direct Ethernet connections into the router.

    A．Full-duplex Ethernet uses CSMA/CD to prevent collisions.

    B．Half-duplex Ethernet uses a loopback circuit to detect collisions.

    C．A full-duplex Ethernet card allows 20Mbps for data transmission.

    D．Full-duplex Ethernet makes use of two pairs of wires for data.

    E．An Ethernet hub can operate both half and full duplex simultaneously.


    正确答案：BD
    解析：Explanation:
    Half-duplex Ethernet send and receives on the same line, so a loopback needs to be set to detect collisions. Alternatively, full-duple Ethernet doesn't have to because it uses two pairs of wire, one to send and the other to receive. Collisions are not possible on full duplex Ethernet networks.

    Incorrect Answers:
    A. Full duplex uses both pairs of wires, so transmissions are sent on the first pair, and data that is received come in on the other pair. This prevents collisions.

    C. Full duplex allows for data to be sent and received at the same time. It will not double the amount of bandwidth at any given time. The speed of the Ethernet link will remain at 10/100.

    E. Hubs are shared devices and can only support one mode, unlike switches.
