我也是 感觉其中几个题答案有问题。做的时候，都有点怀疑自己了

楊魯夫

感謝整理  我也這麼覺得這幾題有問題!!

ryanyue11

177我觉得AD都对，但是A的描述包含了D的描述（看视频的讲解）。其他都同意的

unkleenever

都是有争议的，希望乔帮主能在论坛能有回复，当然前面都是题库答案

netveteran

问题385，答案应该是AB. 因为TFTP 和SNMP是基于UDP的，SMTP是基于TCP的。

补上 上面说的，

LINK 与 LINEPROTO的区别，虽然都是 端口的up/down，但是 3的updown 是link，5的up/down是line protocl。
