After several months of efforts, I still can not take part in the CCNA exam. There is a little pity to this. One famous wisdom says: The life is full of so many frustration. I know the words, so I do not sigh too much. In recent days, I remember that I should study something. Too quite life will get rid of your will. At last, I choose the CCNP, on one hand, I am interesting in it. On the other hand, I once study the CCNA course.

Tonight, I will the uncover the secret veil of CCNP. But, I study it, no for pass the exam. I study it for the technology only! Don’t laugh at me, ^_^. Looking forward to the CCNP book.HOHO!
