Vinh Danh, CCIE #25004

Hi IE team, I almost passed the first time in June, but Cisco decided to give me a second challenge. So I went back to Brussels yesterday ... and passed my CCIE RS #25004 For the preparation, I've read : - Cisco CCIE Certification Guide - Routing TCP/IP Vol I,II - Cisco QoS Exam Certification Guides - and Cisco Doc CD for everything I practiced 7 IE MockLab the last 3 months and also used Core Knowledge Simulation. I must say that IE products really help me to point out what I have to read and pratice deeply. Thanks guys for all your great job. I will definitely go with IE for my next track. All the best to IE team and keep up the good work.
