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：
