I have been trying to climb the hill that is the CCIE R/S going on five years now. While I’m still struggling to get there, I used the CCIE R/S videos from INE to increase my knowledge. While I don’t yet have my number (I will though!), INE's material has actually increased my knowledge tenfold, so much so, that I have been able to get basically any job that I have applied for. During interviews, I am able to answer almost all questions and I credit that to the information that I learned through INE and labbing every day. Also, the videos helped me deeply understand the concepts. I’m grateful for the knowledge that I have gained and know that it will one day help me reach my certification goal.
