Mohammed Mahmoud, CCIE #19473
I've passed my CCIE R&S lab exam from a couple of weeks, your CoD is a very valuable product, and it is sincerely one of the reasons of success, i am wondering if you have a similar product for SP, as i am going to prepare for it in the next couple of months. At the moment i am not sure of Brian Dennis and Brian Mcgahan emails, i've guessed them :) , please make sure to forward this thank you email to them if my guessing was wrong. Thank you very much for making a difference. I really can't imagine my CCIE road without you guys.
