I just took 640-802 exam and got my CCNA certification. It may sound funny. I have taken this exam after ten years of experience in networking but I was very nervous!
Why do I need a Cisco Certified Network Associate certificate?
Actually, I did not have plans for certification. If I get a CCIE certification, it would be good for my career (not for salary but if I change my job). On the other hand, I was afraid of to take the CCIE exam. I do not have a good history with exams. I could finish my Computer Science degree in ten years while normal period is just four years!

Two months ago, I heard that 640-801 exams will be expired and Cisco added one more milestone to career path as CCENT. I told my wife about it and she gifted me an exam fee to take up the exam. I had all this pressure on me.

Preparations and exam
I managed to get two days off, one day for preparation and one day for the exam. I also spent the last three evenings for this purpose. I did not attend any Cisco training class and use only CCNA Prep center (Exam Study tab) for preparation. This web site is very useful and the content provided is sufficient for experienced professionals. If you start from scratch, it will be good for you to attend a Cisco CCNA class, but not a CCNA bootcamp. This is not a big deal. Don’t waste your money.

Exam day did not start very well. The weather was rainy. There was a traffic jam. I reached the exam center just five minutes before my reservation. A cute girl told me that I can start two hours later because of some technical problems. I spent that time in a café (well-known chain), near the exam center. I realized again, these cafes are not as good as people believe them to be (tables, pictures etc. fine but what about the taste). When I returned to exam center another cute girl told me that they are just downloading the exam. I had to wait 15 minutes more. Cable paths caught my attention, I easily came to know that bad materials were used and it was installed by an inexperienced staff.
