Woah… Deja Vu This all seems so familiar… OH YEA! I went through this once before already. I took the CCIE R/S version 3 with the high (naive) hopes of passing it my first attempt. #n00b The challenge I had with the R/S v4 update was that it felt like the content managers had a serious case of ADD.
