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.

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.

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.

Useful, a wide range of questions and good structure.

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!

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.

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.
