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 self-paced 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 customers to think like a network designer by applying technology to meet business requirements and design specifications.

Orhan is forcing you to take off the implementation hat that most of us have been wearing for many years, instead he is providing a new fancy design hat, which makes you see and deal with the issues presented. At the beginning of this CCDE course you many times are sitting thinking ‘I could solve this issue with some fancy trick/feature’, all because you keep thinking implementation. However as the course goes on Orhan is helping you to fill your new fancy design hat with all the important information not only for designing, meeting business requirements, but also dealing with the interaction of the protocols. If you’re trying to get your head into a new hat, chasing the CCDE exam, or just wants to get on top with network design, I would go to Orhan today.

I passed the CCDE exam on November 17,2016.Orhan’s CCDE Live class and Self Paced training course helped me a lot to pass the both CCDE Written and Practical exams.Design comparison charts and videos will help you a lot in CCDE Practical exam. The quizzes in the self paced CCDE course is excellent resource for the CCDE Written exam.If you are studying for CCDE exam or want to learn network design,I strongly recommend you to take this course.

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

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.

Thanks Orhan for everything !

Orhan’s #CCDE Bootcamp has been a great resource for me. Orhan goes into a great level of detail to explain the design implications of each technology and the relationships with other technology that it could affect. Orhan’s case studies in each technology really pull everything together. One thing to state though, this is not something you should just take on a whim mind you, you really need to have the R&S and SP experiences to go down this path. Orhan’s CCDE Bootcamp is more focused on the case studies than teaching the theory of the technology. Orhan does go over the theory for each tecnology but this should be a review and not used to learn the technology for the first time. If you have the R&S / SP experiences to backup your understanding of the technology then I think Orhan’s CCDE Bootcamp is perfect for you.

Training by Orhan is not a CCDE preperation training only. It will be usefull for engineers which are dealing with designing networks in their daily basis. Orhan’s CCDE training gives detailed understanding not about field implementation of technology such as IOS commands,debugs etc, but it gives you understanding about how technology works, or which technology to choose in particular busines case, when,why and how to design it’s architecture. And after that Orhan guide you through “what-if something fails”cases, which are gives you more deep understanding about information you must take in consideration in you further technology selection and designing process to be sure that you network will not just work, but also will be stress resistant. Highly recommended for the network engineers,designers and solution makers. You will get live lectures, discussions and mentor which is always ready to help you and even discuss topics that are not covered in CCDE but are really important in design process. CCNP/CCDP/CCSP
