NA在IPv6和无线方面考的很浅的 在这两方面考试题型都是选择题 实验和拖图题不会考这2个部分
IPv6方面
1.考哪些是合法的IPv6地址 IPv6环回口地址
2.IPv6的基本概念
3.IPv4到IPv6的过渡技术
无线方面
1.给你一个场景 比如有部分人无线网速很慢 但有些人网速很稳定 是什么原因导致的（无绳电话、天线方向、金属物体干扰）
2.会区分ESS和BSS
3.哪些东西会干扰无线网络（无绳电话cordless phone、微波炉microwave oven）
4.配置无线网AP的基本三要素：SSID、RF channel、authentication method
也许上面我说的你不是很明白 不过CCNA学习指南这本书里都有详细说
还是给你看看几个具体的NA考试题吧 你就应该能大致知道会考哪些内容了（以下都是NA的真题 出自NA题库）
IPv6的NA试题
