4 @2 [2 `0 v7 D5 fPASS截图我就不放了,现做以下分享
3 b; i8 c [+ j. o8 d) O继5月26日400-101fail之后的又一次挑战,今天终于pass了,面对着思科的各种变题,本以为我不在持续继续参加考试;上次本以为笔试fail之后就不在考思科了,可作为一名刚刚毕业的专业生,不得不考一个还算可以的证书;现在工作在某个不知名小公司,每天和PC打交道,确实厌倦了这种生活,别的的就不说了, 希望一下题目对大家有帮助。( n. w9 m2 v2 @. g
特别感谢在463904693群内得到大家的帮助,虽然有部分新题,但是我还是由衷的感谢,有兴趣的话大家也可以进去。
