Can you all believe that someone can make it to CCIE, yet not really know their stuff? About 8 months ago, I worked with four CCIE's, three of them were as you would expect, very knowledgeable. The last one, he must have done brain dumps for each of his tests, and I don't know how he passed the CCIE lab (although in fairness, I don't know what the CCIE lab really consists of). I remember he was trying to troubleshoot getting our new Ciscoworks and TACACS+ servers up, and I was his assistant of sorts. My job was to test the cables between the servers and the switch, and basically get him anything that he needed. After testing the cables about three times, verifying they were good, he decided that somehow the cables were bad, and he wanted me to run new ones. At this point, I looked at the laptop he was using to console into the switch and saw that the switchports were shutdown. Yes, I later learned he got fired from his company because of his job performance.
Brain dumps may allow you to achieve a goal of certification, but when you get on the job, people will be able to tell.
