Reviews and Testimonials
Great Study Guides!
Useful, a wide range of questions and good structure.
Excellent material to study for CCIE Written. I recommend it to all who want to learn for CCIE
The CCIE R&S definitely provides great, precise and complete training materials. I am highly impressed by the complete training materials as preparation not only for CCIE R&S but also helps a lot on review for CCNA R&S. This is awesome and I will definitely recommend this to my teammates and friends.
Three days studying this material and I feel comfortable and sure that I’ll pass the written exam!
CCIEin8Weeks is the product to use if you are going to be passing the CCIE Written! Thank you for the book, the great customer service and the abundance of information!
I was very impressed with the structure of the study guide for R&S. Used in addition to other materials this package is a brilliant resource.
So far, this has exceeded my expectations. I was struggling with studying for the 400-101 in a methodical manner and now I have a dedicated study schedule with material that doesn’t run down rabbit holes.
Very clear and concise content. I really appreciated the video content and how they understood that some of the material could be dry, so they tried to mix it up a bit by adding “fun facts” to the content. I would recommend and will be purchasing other material in the future.
Well structured and very helpful
The best material available today for CCIE Written preparation!
Great study materials. Very thorough and complete. Extensive coverage of the topics. There is a lot to review, and will take some time, but if you complete all of it, you will be well prepared. Well worth the price.
I stumbled on this site by accident a few months ago, and since then my study for CCIE Written for R&S has never been much easier. Of particular interest is the Evolving Technologies section. I am yet to come across any CCIE learning sites that have better content than those in this guide for the new Evolving Technologies. I would definitely recommend to anyone wishing to undertake the written exam.
Very well put together, and thought out, Move along a good pace, and explains exactly what you need to know. Great refresher for those that have already passed, but are looking to pass again for re-cert. I would recommend this guide!
I came across this site while preparing to sit for my CCIE R&S exam. I have studied the material in depth before, but needed something that would give me a concise overview and an easy to follow map to quickly find the content I need to review. The study guide material is put together very well and organized by exam topic, which is exactly what I needed. There are also links to documentation for further reading where necessary. The exam questions are also great to further your retention of the material. The study guide has been a valuable preparation resource.
I highly recommend this study material. It helped me pass the CCIE Collab Written exam a few weeks ago. I agree with the other reviewers – it’s definitely the best study material out there (besides Cisco guides).
Excellent for people who don’t want to read the whole book and also quizzes are very useful to practice.
Good product in market to pass CCIE written and contains good amount of information
I am an CCIE R&S. This product really helps me re-certify my license. The product has very realistic problems with links to useful documents. It lists a lot of problems that cover all necessary topics. In short, studying these materials really make me study and well prepare me for the test!
Well compiled content for preparation of the exam and understanding of concepts relevant to the Course. Well articulated for preparing one to take on the exam
I have used CCIEin8Weeks to prepare for CCIE CCIE Data Center 400-151 and I find the product excellent preparation material, highly recommend it.
Excellent test prep for CCIE written exam. Really like that when you get answer wrong it has link to documentation with explanations. Also, a plus is the test questions are updated frequently!
The study guide provides a nice breakdown of the blueprint with links to additional reference material which provides a good refresher. The study plans are a nice touch and help keep you on track when you have a busy schedule.
Small investment for a larger return! The CCIE DC All In One Membership has been an essential resource in studying for my CCIE Datacenter Written exam. This product alone takes the abundance of criteria outlined in the exam blueprint and condenses the essential material into a Study Guide and Practice exams which provide a real-time experience in preparation for your exam. Highly recommended!
I am reasonably impressed with the content in this book, to help kickstart my certification efforts.
Very useful content
Study guide provides concise information for all areas of exam and provides a link to more details for each section. I would recommend to anyone that is ready to take the written but wants to review main points before taking.
Great product, well organized study guide and the quiz questions lead you in the right direction to further study.
The pdf is very helpful and contains a lot of knowledge that is not found in other products. The study plan and quizzes are excellent.
I am shocked and amazed at the amount of material that I have now for my CCIE written, It has cut down on the time for collecting right resources for the prep. It is a perfect place with all resources like full documentation, Videos and practice tests.
A very nice reference PDF for CCIE Security Studies. Hits all of the topics listed in the blueprint, and has become a helpful resource in my studies.
