Le Duy Khanh, CCIE #48719
I passed my CCIE RS lab exam at my 1st attempt at Singapore in May, 2015. It took me 20 months since I passed the first written exam. It was pretty hard time to me when practicing your workbook but it helps me so much. I would like to say thank you to all IEOC community members - it was a pleasure to study with you guys. My dream is truth and now my next target is Collaboration and for sure I will still use your workbook. Thanks you so much!
