  • 第1题：

    Which of the following correctly describe the various functions and virtues of a router? (Select all valid answer choices)

    A. Packet switching

    B. Collision prevention on a LAN segment.

    C. Packet filtering

    D. Broadcast domain enlargement

    E. Broadcast forwarding

    F. Internetwork communication

    G. None of the above


    正确答案：ACF
    A,C,F 解析：Explanation:
    The main function of a router is to connect different, separated networks together. In doing so, switching packets from one network to another is a primary function, along with providing for communication between networks. As an additional feature, routers are capable of providing filtering on a network address and application port level, so choice C is also correct.

    Incorrect Answers:
    B. Routers can indeed be used to segment a network separate a collision domain, since routers do not forward LAN broadcasts and multicasts to other interfaces. However, routers alone can not prevent all collisions from occurring on any given LAN segment.

    D. Routers actually segment LANs into smaller broadcast domains.

    E. Routers do not forward broadcast and multicast traffic out the additional interfaces by default. Unless bridging or IP helpers are configured on the router, LAN broadcasts are blocked at the router level.

    Expressive.

    B

    Unselfish.

    C

    Realistic.

    D

    Tough.


    正确答案： A
    解析：
    推理题。注意题干中的关键词NOT。根据题干定位至原文描述作者母亲的部分，即第四段。该段中作者谈到自己的母亲时说到：…she set a selfless and hardy example.由此可知B和D两个选项是上述两个形容母亲性格的词的同义表达，故不能选。根据该段内容还知，母亲为了生活把作者(长子)当作自己的帮手来维持生计说明母亲是个现实的人，也排除C。并且该段的最后提到：I thirsted for my mother’s attention. … I clearly recall, at the ripe old age of 7, coming to the conclusion that I would never get it.说明作者想要得到的是母亲的关注(attention)和爱(love)，而他永远得不到这些，但这并不是说母亲不爱他，只是母亲不善于表达自己的情感，因此A选项的“善于表达的”并不是母亲的性格。本题为反选题，故正确答案为A。
