Daniel Haun, CCIE #22791
INE's workbooks were my primary study tool used to complete my Security CCIE in 2008. The combination of the two volumes fit my needs exactly; volume one filled in the gaps for technologies I wasn't already familiar with, and volume two let me practice integrating them in a single topology. After completing all ten labs in volume two, the actual lab exam seemed easy - I passed on the first try with two hours to spare. I have since purchased the workbooks and ATC for Routing and Switching and have already benefited from them.
