    Which of the following statements correctly describe the differences between half-duplex and full-duplex Ethernet? (Select two answer choices.)

    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.

    Ezonexam users have noticed extremely slow network performance, intermittent connectivity, and connection losses. After entering the "show interfaces" command, you notice that the Ethernet interface is configured as 100 Mbps full-duplex and that there is evidence of late collisions. What could be the cause of this problem?

    A. Duplex mismatch

    B. A routing loop

    C. Trunking mode mismatch

    D. Improperly configured root bridge

    E. Improperly configured static VLAN

    F. None of the above


    正确答案：A
    A 解析：Explanation:
    A duplex mismatch may result in performance issues, intermittent connectivity, and loss of communication. When troubleshooting NIC issues, verify that the NIC and switch are using a valid configuration. Some third-party NIC cards may fall back to half-duplex operation mode, even though both the switchport and NIC configuration have been manually configured for 100 Mbps, full-duplex.

    This behavior. is due to the fact that NIC autonegotiation link detection is still operating when the NIC has been manually configured. This causes duplex inconsistency between the switchport and the NIC. Symptoms include poor port performance and frame. check sequence (FCS) errors that increment on the switchport.

    To troubleshoot this issue, try manually configuring the switchport to 100 Mbps, half-duplex. If this action resolves the connectivity problems, you may be running into this NIC issue. Try updating to the latest drivers for your NIC, or contact your NIC card vendor for additional support.
