Many students will ask before they take CCIE tests: What should I prepare? What ability should I have? What on earth should I do? Now, I'd like to give u my personal advice on some big aspects.
First of all, theoretically, you need to read as many books as you can. TCP/IP volume one, volume two must be read at least 2 times. You must completely understand those basic theories. There are many relevant books on the Internet, read, read, read!
Secondly, you need to be prepared for the long time "battle". CCIE certificate is a very valuable certificate. So even if you are a talent, it can't be easily got without longtime hard-working.
Thirdly, it may cost you a lot of money. Both training fee and test fee are not cheap. However, if you do get the CCIE certificate, you will earn back how much you spend in a short time.
The last but not the least, you should have a strong will. I mean, be prepared to face to the same computer every day, and to keep hitting the same keyboard all the time.
CCIE exams are divided into two parts: written exam and lab. Students must pass written exam first then lab. Most agencies will have a mock test before the real one. If you can pass the mock test, probably you can pass the final test too.
It's not hard to pass the written exam, but it's not easy to pass the lab exam. To pass the lab exam requires strong professional knowledge. You'd better go to a reliable training center to study first, then start the professional closed-off training and pre-exam guidance.
Two ways to success:
1, Self-study. To get the CCIE certificate by self-study requires more than two years working experience, enough time and high spirit, and a perfect experimental environment. What's more, you must have perseverance, never give up.
2, Attend a training center. Make full use of the training center's experimental equipment. Communicate with other students. The most of all, you can get the CCIE experts’ guidance to improve learning efficiency. This is a way to get twice the result with half the effort.
