考题 IPv6包头比IPv4包头更长,格式比IPv4复杂。() 此题为判断题(对,错)。

考题 阅读下面一段短文,然后回答下列 36~38 小题。第 36 题 概括本片段的大意。作者的观点是什么?

考题 阅读下面短文。回答 26~25 题。第 26 题 下列关于“托迈”的说法,正确的一项是:

考题 在从IPv4过渡到IPv6过渡过程中需要解决IPv6孤岛的互联问题,IPv6孤岛互联的技术主要有以下各种隧道技术:()、()、()、()、()。

考题 为了加快路由器处理数据报的速度,IPv6首部取消了(56)字段,而通过数据链路层和运输层来完成差错检验功能。为了便于地址阅读,IPv6使用(57)记法。在IPv4向 IPv6过渡的方案中;当IPv6数据报进入IPv4网络时,将IPv6数据报封装成为IPv4数据报进行传输的方案是(58)。A.流量控制B.差错控制C.校验和D.纠错

考题 认真阅读以下基于Windows 2003操作系统IPv6的技术说明,根据要求回答问题1至问题4。【说明】由于现有的网络设备大部分都是基于IPv4的,也不可能在短时间内都更新换代来支持IPv6,因此在相对比较长的一段时期内,IPv6网络将和IPv4网络共存,然后再逐步实现IPv4向IPv6的平稳过渡;同时在实施IPv6网络时必须充分利用现有的网络条件来构造下一代因特网,以避免造成过多的投资浪费。一台Windows 2003操作系统的主机上同时安装了IPv6和IPv4两种协议,该主机既可以和仅支持IPv4协议的主机通信,也可以和仅支持IPv6协议的主机通信,这种实现IPv4向IPv6的平稳过渡的通信方案称为双协议栈技术。基于该技术的协议栈结构如图7-10所示。请从以下供选择的答案中选择适合的选项填入图7-10的相应位置。【供选择的答案】A.IPv6协议 B.IPv4协议 C.应用层协议 D.TCP/UDP协议
