Student's Feedback
See what our students have to say about their learning experience
Mehdi Sfar
Network and Security Architect / CCDE #20210003 | CCIE R&S; #51583
"I signed up for Orhan’s CCDE Self paced Course. This course, along with the CCDE In Depth book, helped me for my CCDE Practical as well as Written exams. It pushed me to ask the "WHY" questions and allowed me to grow as a network architect. The use cases, quizz, and compare charts are all great."
Daniel Lardeux
Senior Network Consultant at Post Telecom
"I passed the CCDE Practical exam and Orhan’s CCDE course was very important contributor to my success. I attended the CCDE course of Orhan Ergun in July and it was exactly what I needed, Orhan is taking the pain to break down the different technologies."
Nicholas Russo
Network Consulting Engineer (CCDE/CCIEx2), Cisc
"I signed up for Orhan’s CCDE training. This training is very technically detailed and the use-cases, quizzes, scenarios, and mind maps are all great resources in the overall training program. Orhan teaches his students to think like a network designer by applying technology to meet business requirements and design specifications."
