Chun Man Chow, CCIE #26095
Thanks for producing such an amazing product. I was heavily rely on INE workbooks volume 1 and 2, and the OEQ, along with the CCO and other Cisco official materials. After 1500hrs of solid study + labbing, I was able to pass the CCIE security lab in my first attempt in 26 May 2010 @Sydney. Thanks again for the finest CCIE products in the market which contributed to my success.
