Ruben Lopes da Fonte, CCIE #27124
Initially, I used many books which gave me a foundation for the CCIE Service Provider Written. I then attended the CCIE Service Provider bootcamp in Chicago in October last year, and I had the privilege of being able to buy the videos, both which were the key to my success. Thanks INE. Highly recommend to all. My next step is to tackle the CCDE using INE's products.
