    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.

  • 第13题:

    You are working as a network technician at Ezonexam University, when you get a call from the Engineering Faculty. They're complaining that they're receiving obsolete information from the Business Faculty's network traffic broadcasts.

    What can you do to contain the Business Faculty's broadcast while still keeping it connected to the internet and the enterprise services of the University? (Select all valid answer choices)

    A. Use half and full-duplex Ethernet on the Engineering Department LAN

    B. Establish a VTP domain to minimize the obsolete traffic

    C. Change the switch IP address of the switch

    D. Create separate VLANs and subnets for the two departments and route between the two

    E. Provide greater bandwidth to the Engineering Department LAN

    F. Place the business department on a separate subnet and route between networks


    正确答案:DF
    D,F 解析:Explanation:
    In order to prevent the broadcast and link level multicast traffic separated between the departments, they need to be isolated at layer two. This can be accomplished in two ways. The first is to create separate VLANs and place each department into a different one. The second method would be to separate the two departments into two completely different networks, and route between them.

    Incorrect Answers:
    A. Mixing the use of half and full duplex will make no difference to the number of broadcasts sent.

    B. Trunking is only useful in networks that already contain VLANs.

    C. This will make no difference, as all users will still be contained within the same IP subnet.

    E. The amount of bandwidth involved will not have any impact on the amount of broadcasts that are sent and received.
