I passed the #CCDE today! I used a lot of resources to be successful but I need to call out one specifically. Thanks Orhan Ergun for always being available at all hours to answer every question, to discuss every technology, and to work through my personality “issues” that I had throughout this process!! For all my friends venturing down the CCDE path Orhan is a great resource and friend to have!

Orhan’s ability to cover the vast topics required for CCDE is tremendous. He is not only very technical, he is also an amazing teacher.

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.

After I attended Orhan Ergun’s CCDE course I passed the CCDE practical exam.I really enjoyed the course a lot.

Before I signed up I didn’t know what to expect but it’s for sure a great design course and preparation for the CCDE exam. Mainly because of the interaction with Orhan who is really an expert in explaining all the different technologies and making perfect designs out of them.

I passed the most respectful Cisco exam CCDE on August 2016. I became first Nigerian CCDE and Orhan Ergun’s CCDE Bootcamp was the most important resource in my success.If you want to nail down CCDE, you need to think as a designer. You need to change your mindset and understand all the technologies in the CCDE Blueprint.Orhan’s resources cannot even comparable with the any CCDE Training provider in the industry.I would highly recommend the Orhan’s CCDE Bootcamp for anyone who want to pass CCDE exams and understand the real life network design

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.

If you are considering studying for the coveted Cisco CCDE certification, make good use of the Cisco recommended reading list and CiscoLive videos focused on design. But your preparation won’t be complete without a touch of Midas from the master CCDE trainer Orhan Ergun. He is the most complete training provider in the industry – Books, Blogs, Videos, Bootcamps, One-to-one chat, etc.Self Paced Course is a best offline CCDE resource !

I’ve used Orhan’s self-paced CCDE training material. If you are interested in knowing how all the technologies go together in a coherent design i can highly recommend it.I also enjoyed the Quizzes which helped pick out my weak spots in selecting an appropriate design. So if you are serious about either learning more about the design aspects of networking or you are going for the CCDE practical, you should take a hard look at Orhan’s Self-paced Training option.

The eleven days spent in Orhan bootcamp was invaluable in helping me build confidence and master my design concepts. After a long number of reading books and watch all the Cisco Live design sessions, this class was definitely the advantage I needed to take and pass my CCDE lab. Thanks Orhan for your all supports

Hi Orhan. I passed the CCDE exam on February 22. I read everything that you put on your Self Paced CCDE Training course and it was very helpful in my success. Thank you very much.

Thanks Orhan for your Instructor Led CCDE Bootcamp. It was very informative for CCDE Written and Lab preparations. Personally we used to discuss designs related to production networks (ISP,DC/Enterprise) & I must say he is technically sound in Network Design. I am impressed with your technology comparision charts when it comes to selection of routing protocols, VPN technology solutions etc.
I strongly recommend Orhan Ergun’s class if you want to pass the CCDE exam and learn network design.

I passed CCDE exam on first attempt and Orhan’s bootcamp helped me switching mind-set from an engineer to designer.

Thanks again Orhan for your Instructor Led CCDE Bootcamp.

I attended Orhan’s April 201610 days CCDE Bootcamp. I am CCDE now !

You can tell Orhan has a great deal of experience, it really comes through when he presents his design case studies and the CCDE Practical scenarios.

Your excellent CCDE materials and amazing Bootcamp helped me tremendously through my learning journey.Also thank you very much for being available whenever I have a design question or a complex design topics. I can’t compare your design skills and training with anyone in the industry.

I definitely strongly recommend you whoever wants to understand the network design in detail and wants to pass CCDE exam.

Orhan is the best teacher in network design, I have learned a lot from him about the CCDE and real life network design.

I became a member of orhanergun.net for the CCDE preparation. For CCDE exam, there are very few quality trainings available

I was super excited to the take the online class and I’m happy to say that the class was way beyond my expectations.

Orhan’s Bootcamp is really informative; I gain lots of knowledge from him. It helps to prepare the CCDE; Also in your work environment. I recommend my friend and colleagues to join Orhan once to get the great knowledge about Network Designing

I was glad attending Orhan online CCDE class last year. The manner he delivers the topic and explains each of our questi

Your excellent CCDE materials and amazing Bootcamp helped me tremendously through my learning journey. Thank you Orhan

I attended Orhan’s CCDE Bootcamp and it was great. He contributed immensely to our knowledge, Thanks Orhan for all your help!

I attended Orhan’s Pre-CCDE class and it was really helpful for me. Pre-CCDE class was a good introduction to the CCDE

Thanks Orhan very much for this course. It helped strengthen my “Network design mind”.

Training by Orhan is not a CCDE preperation training only. It will be useful for engineers which are dealing with design. You want to pass CCDE exam or learn network design, then don’t look at anywhere else!

Orhan Ergun’s CCDE course was really very good. CCDE Level Intelligence was delivered very well and with very useful case studies and the scenarios, I am thankful to Orhan for all his help!

I passed the CCDE Lab exam thanks to Orhan. Orhan’s CCDE Course is great CCDE Resource. The course is detailed with technologies, practical scenarios, real life network design examples and many other things. Orhan will guide you personally which will help you to become better network engineer and designer. I will attend all other courses which Orhan produces and teaches, that’s for sure!

If anyone wants to understand network design and architecture, also pass CCDE exam , I recommend you to attend Orhan’s online courses! I am a CCDE now but learning is a journey, we will be together in your other courses too Orhan!

Orhan did an excellent job of filling in the gaps of knowledge that I had that took me to the finish line of the practical exam CCDE. The community of people that Orhan facilitates are both engaging and supportive of the journey to CCDE. Orhan was always quick to answer any email or chat messages that I sent him. Overall I am very happy with the time spent engaged in the material and bootcamp. Thanks Orhan!

Orhan, I came, I learned and now I got my CCDE number!

For those who prepare for the CCDE Practical exam, all what you need is some experience and Orhan’s guidance! Thanks Orhan for all your help! Dima.

Just passed the CCDE Practical exam! I attended Orhan Ergun’s CCDE training program , used Orhan’s Instructor Led and Self-Paced CCDE training and Online CCDE Practical Scenarios during my CCDE journey. Orhan’s CCDE In Depth book is an excellent summary book about almost all topics related to CCDE. Orhan’s practical scenarios are well organized and discussions in his webex are very valuable. Orhan’s also from time to time host webex lectures on different technology topics, I find it’s another revenue to refresh and strength my understanding of different topics. Orhan’s study group is very active, different peers share their experience, discussion and insight on not only the CCDE but also different technologies.

I surely appreciate Orhan’s excellent training materials, constant guidance and demonstrated dedication to help me get CCDE. As always, life is a constant learning experience, CCDE is only one of small steps!

Hi Orhan I passed CCDE Practical exam on November 2017 ! I really enjoyed your materials and quizzes and use cases. They were definitely helpful in my preparation. Thanks a lot !

I attended Orhan’s CCDE Training in Istanbul and it was very helpful in my preparation. I passed the exam recently and I want to say Thank you Orhan! For those who want to pass the CCDE exam, definitely start with Orhan!

I registered to Orhan’s training in Feb 2017. From that time, I attended Orhan’s training several times. The depth of knowledge which Orhan has is amazing, and how to present such consistent knowledge to the trainees was indeed appealing.
Furthermore, Orhan is not only trainer, he was real mentor to me, He showed me the concept that “Where I’m now, and where I should go”, this is indeed the true leadership !

Hi Orhan

I wanted to pass along my appreciation for the outstanding training material. I used the online CCDE training provided by Orhan as well as the In-Depth-CCDE book and passed the exam in February 2018.

Thank you Orhan!

I passed the CCDE Practical Lab exam on November 17,2016 from supplications of elders and dedication from my Sensei Mr. Orhan Ergun I took different CCDE bootcamps in the past. Orhan has the most depth and expertise. You can discuss with him at an expert level on different technologies and he is focused. Both the bootcamp and his book helped me a lot in achieving the design skills to nail this beast. I would recommend taking his CCDE training to pass CCDE exam and learn the network design
