思科CCNA考试200-301练习题库参考资料
今天在个群里，看到群主分享了个CCNA考试题库，有考友说看这题库覆盖能到80%以上，自己学这方面的，配合这题库参加考试没问题，要想更完整，覆盖更全的题库，还是建议要花钱去购买了，毕竟考试费也不少钱呢（300美元），题库上省钱了，可能考试费上就费钱了。参考我之前的题库由来文章：https://bbs.hh010.com/forum.php?mod=viewthread&tid=649360，自行判断看什么题库去参加考试。看免费的题库还需要多看些书籍教材学习指南，切勿盲目迷信题库，因为它是免费的便宜的，一分钱一分货，本身的价值等于金钱的价值。以下题库内容大致抽题介绍，包含了实验题，选择题，拖图题，判断题等等，下载地址在最后：QUESTION 17Which two minimum parameters must be configured to enable OSPFv2 to operate?
