I would like to take a moment to thank the Internetwork Expert team especially the 2 Brians and Alissa. I passed my R&S lab this past Friday in San Jose, CA on my second attempt. The materials offered by Internetwork Expert is second to none. Without the materials and advices, my preparation time could easily have doubled or even tripled. The systematic approach and detailed explanation from Advanced Technologies Class on Demand have made the technologies so much easier to learn and understand. All the workbooks are written with great care and offers a feel for the real exam. Security is coming up next and see you soon Internetwork Expert.
