First Thank you INE for the great blog and available videos, it helped me a lot to understand the technologies. Also, I used the Narbic book and Cisco materials and I did practice on both GNS3 and real gear for more than 18 months. I did a good amount of practice with 10 hours daily, and I went through all the success stories to see what they did it was important. Thank you all.
