于9月15号通过了cisco的ccna考试,事实证明现在cisco证书的含金量已经全不如当年,同去的一个女孩子全然不懂英文,硬生生把所有要考的题目的答案给背了下来,考试的时候看完题目直接勾选答案,考的分数比我还多,这些考生基本上属于没事凑热闹类型的。有朋友问我既然这样为什么还要去考这么个东西,其实我只是想做个职业生涯的总结,如此而已。
早上7点钟的时候一车人从杭州文三路的数码广场出发,浩浩荡荡直奔上海,事后我想起来这件事有点搞笑,这怎么有点像古代的进京赶考一样,只是把毛驴换成了面包车而已。
要想通过ccnp考试,必须通过四门课程,其实这些在ccna里面多有提及,只是涉及的知识面并不广泛,在ccnp里面进行了延伸,可以分四次或者三次考试来完成ccnp认证:
CCNP Exams & Recommended Training
642-901 BSCI Building Scalable Cisco Internetworks (BSCI)
642-812 BCMSN Building Cisco Multilayer Switched Networks (BCMSN)
642-825 ISCW Implementing Secure Converged Wide Area Networks (ISCW)
642-845 ONT Optimizing Converged Cisco Networks (ONT)
OR
642-892 Composite
Building Scalable Cisco Internetworks (BSCI)
Building Cisco Multilayer Switched Networks (BCMSN)
642-825 ISCW Implementing Secure Converged Wide Area Networks (ISCW)
642-845 ONT Optimizing Converged Cisco Networks (ONT)
其中642-892包含了BSCI和BCMSN两方面的内容,放在一起考试难度还是有的,剩下的时间就是准备银子死磕ccnp,回想起来我已经数年没有参加过任何类型的考试了:
