摘要：对于【网络工程师】软考考试而言，试题无疑是最重要的学习资料之一。在软考备考过程中，吃透试题、掌握试题所考知识点、熟悉试题的出题思路，对我们提升分数的效果是最明显的，通过对试题的反复练习，还可以查漏补缺。今天，给大家带来【2013年5月 网络工程师 上午题】部分试题的详解，一起来看看吧~



1、网络设计过程包括逻辑网络设计和物理网络设计两个阶段，每个阶段都要产生相应的文档。以下选项中，  （70）  属于物理网络设计文档。
A、 网络IP 地址分配方案
B、 设备列表清单
C、 几种访谈的信息资料
D、 网络内部通信的流量分析

答案:B
答题解析:

略

2、请作答71题:Although a given waveform may contain frequencies over a very broad range, as a practical matter any transmission system will be able to accommodate only a limited band of   （71）  . This, in turn, limits the data rate that can be carried on the transmission   （72）  . A square wave has an infinite number of frequency components and hence an infinite   （73）   .However, the peak amplitude of the kth frequency component, kf, is only 1/k, so most of the    （74）   in this waveform is in the first few frequency components. In general, any digital waveform will have   （75）   bandwidth. If we attempt to transmit this waveform as a signal over any medium, the transmission system will limit the bandwidth that can be transmitted.
