1.As the Ezonexam network administrator, you are required to have a firm understanding of the OSI model. Why does the data communication industry use the layered OSI reference model? (Choose two)A．It enables equipment from different vendors to use the same electronic components, thus saving research and development fundsB．It encourages industry standardization by defining what functions occur at each layer of the modelC．It divides the network communication process into smaller and simpler components; thus aiding component development, design and troubleshootingD．It provides a means by which changes in functionality in one layer require changes in other layersE．It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers

  • 第1题：

    At which layer of the OSI model does the protocol that provides the information displayed by the "show cdp neighbors" command operate?

    A．Transport

    B．Physical

    C．Application

    D．Data link

    E．Network


    正确答案：D
    解析：Explanation:
    CDP is a device discovery protocol that runs over Layer 2 (the data link layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches) and allows network management applications to discover Cisco devices that are neighbors of already known devices. With CDP, network management applications can learn the device type and the Simple Network Management Protocol (SNMP) agent address of neighboring devices running lower-layer, transparent protocols.

    The TCP/IP stack is a complete set of networking protocols. The OSI Model was meant

    to be a standardized way of connecting devices together. and most protocols have some direct

    correlation to the OSI Model. The OSI Model has 7 layers. the foruth layer is called(75)

    A. physical layer

    B. data link Iayer

    C.application layer

    D.transport layer


    正确答案：D
    TCP/IP协议栈是一种网络协议实现。OSI模型是用来进行设备间连接标准化的一种模型。OSI模型包含7层，第四层是传输层。

  • 第3题：

    OSI is a theoretical model that shows how any two different systems can communicate with each other. Router, as a networking device operate at the（）layer of the OSI model

    A.transport
    B.application
    C.network
    D.physical

    答案：C
    解析：
    OSI是Open System Interconnect的缩写，意为开放式系统互联。国际标准组织制定了OSI模型。这个模型把网络通信的工作分为7层，分别是物理层、数据链路层、网络层、传输层、会话层、表示层和应用层。路由器（Router）是运行在OSI中网络层（network）上的网络通信设备，而不是传输层（transport layer）、应用层（application layer）,或物理层（physical layer），因此选C

  • 第4题：

    For each blank，choose the best answer from the four choices and write down on the answer sheet.
    （ ）is a six bytes OSI layer 2 address which is burned into every networking device that provides its unique identity for point to point communication.
    （请作答此空）is a professional organization of individuals in multiple professions which focuses on effort on lower-layer protocols.
    （ ）functions with two layers of protocols.It Can connect networks of different speeds and can be adapted to an environment as it expands.
    （ ）is the popular LAN developed under the direction of the IEEE 802.5.
    （ ）is the popular backbone technology for transmitting information at high speed with a high level of fault tolerance which is developed under the direction of ANSI.

    A.ISO
    B.ANSI
    C.CCITT
    D.IEEE

    答案：D
    解析：
    MAC地址就是在媒体接入层上使用的地址，通俗点说就是网卡的物理地址，现在的MAC地址一般都采用6字节48bit。
    IEEE是由多个研究底层协议的机构组成的权威组织。
    以太网是共享介质的，物理层接收帧，如果地址和自己的地址一致（或者是广播消息），就留下；反之则转发。因此当主机的数量增加时，网络就会变得十分嘈杂，传送效率明显降低。而网桥是工作在数据链路层的设备，它将一个大型的以太网分为几个小网段，可以取得减少通信量的作用。
    令牌环网是一种符合IEEE802.5标准的局域网。监督帧，即令牌，顺序地从一个网站传递到相临的网站上。希望获得网络访问权的网站必须等到令牌到达之后才能传输数据。
    光纤分布数据接口是目前成熟的LAN技术中传输速率最高的一种。这种传输速率高达100Mb/s的网络技术所依据的标准是ANSIX3T9.5。该网络具有定时令牌协议的特性，支持多种拓扑结构，传输媒体为光纤。使用光纤作为传输媒体具有多种优点：
    较长的传输距离，相邻站间的最大长度可达2km，最大站间距离为200km。
    具有较大的带宽，FDDI的设计带宽为100Mbit/s。
    具有对电磁和射频干扰抑制能力，在传输过程中不受电磁和射频噪声的影响，也不影响其他设备。
    光纤可防止传输过程中被分接偷听，也杜绝了辐射波的窃听，因而是最安全的传输媒体。
