  • 第1题：

    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.

    Which two of the following values does STP take into consideration when it elects the root bridge? (Select two answer choices)

    A. The BPDU version number

    B. The access layer bridge setting

    C. The Bridge ID

    D. The spanning-tree update number

    E. The bridge priority

    F. The VLAN number


    正确答案：CE
    C,E 解析：Explanation:
    The bridges elect a root bridge based on the bridge IDs in the BPDUs. The root bridge is the bridge with the lowest numeric value for the bridge ID. Because the two part bridge ID starts with the priority value, essentially the bridge with the lowest priority becomes the root.

    For instance, if one bridge has priority 100, and another bridge has priority 200, the bridge with priority 100 wins, regardless of what MAC address was used to create the bridge ID or each bridge/switch.

    The Dynamic Host Configuration Protocol provides configuration parameters to Intemet （ ）. DHCP consists of two components: a （ ） for delivering host-specific configuration parameters from a DHCP server to a host and a mechanism for allocation of network addresses to hosts. DHCP is built on a client-server model, where designated DHCP server hosts allocate network addresses and deliver （ ） parameters to dynamically configured hosts. DHCP supports three mechanisms for IP address allocation. In "automatic allocation", DHCP assigns a （ ） IP address to a client. In "dynamic allocation", DHCP assigns an IP address to a client for a limited period of time. In "manual allocation", a client&39;s IP address is assigned by the network （ ）, and DHCP is used simply to convey the assitped address to the client.
