CCIE 25215
"Hi Professor Heinz, Coming to your boot camp was the dawn of CCIE reality and a big wakeup call for me. Prior to my arrival at your boot camp, I actually deluded myself 'in thinking that I was close to being ready for the LAB' I was so wrong, and so far from the truth. With Professor Heinz, I discovered exactly 'how LIMITED I was in terms of knowledge and CCIE readiness' and exactly what the CCIE standard was and how distant from it I was at the time (i.e. in another galaxy). Thanks to Professor Heinz, I was able to make the transformation from mere 'contender status' to 'actual champion' i.e. passing the CCIE Lab. Warning & Advisory Notice, if you are NOT prepared to sacrifice 'your life' to pass the CCIE Lab, then my advice would be to just forget it, cause believe me, it DEFINITELY has the potential to be FATAL !!!!
