CCNA Study Resources

Passing the CCNA exam can be a big challenge for many candidates, as the minimum passing score is 825 out of 1000. That means a passing grade requires 82.5% correct answers. In the CCNA exam, candidates are presented with approximately 60-70 questions to be answered within 90 minutes, and the questions are of following three types:

  • Multiple choice questions (approx. 40-45 questions)
  • Drag-and-drop questions (approx. 5-10 questions)
  • Lab simulations (approx. 5-6 questions)

The above questions do not have equal weight – lab simulations have the highest weight in terms of marks. (Please note that this is empirical observation,per my and other candidates’ exam experience.) However,Cisco never shares the specific worth of individual questions.

Achieving CCNA certification with the highest possible score is not a big hurdle if you get proper training, practice labs and exams, and — most importantly — the best study resources. In this article, we are going to discuss the best and most useful study books and resources used by millions of network professionals around the world for CCNA exam preparation.

Mentioning hundreds of books and study resources here can lead to confusion about how to best review all core CCNA topics. That’s why we will talk only about the most selective, useful resources. In this way, we hope to minimize the amount of wasted time in preparing for this formative certification exam and give you the most bang for your buck.

What are the Best Online Resources to Help You Prep for the CCNA?

Router Alley provides free study guides and key notes on various networking topics, including CCNA prep, to help candidates become recognized as successful network professionals. Each study note is well-written and designed to explore network concepts, from the rudiments to a large variety of command-based implementations. Visit the links to get the available practice labs and study guides.

Intense School CCNA Resources. InfoSec Institute’s sister website, Intense School, provides a topic-based archive of technical articles written by top professionals on a variety of networking and project management topics. You can find a huge collection of articles on Cisco, AWS, BGP and MPLS, as well as book reviews and lists of the top interview questions you might be asked when applying for certain types of networking jobs. Here are some of the best Intense School publications to prepare you for CCNA exam topics and lab simulations.

Please note that many of these articles were written before the update from CCNA to CCNA Routing & Switching. These articles are a good jump-off point for key topics, but not should be a substitute for using a proper study book or class offering.

Fundamentals of TCP/IP Transport, Applications, and Security

Variable Length Subnet Masking (VLSM)

Analyzing Existing Subnet Masks

Understanding Wildcard Masks

Analyzing Classful IPv4 Networks

Introduction to Routers and Their Working

This website is an ocean of GNS3-based labs to cover basic RIP/EIGRP/OSPF to help you to develop your knowledge of Cisco networking.

You can also find the CCNA/CCNP study guide on this website, but that isn’t freeware.

PacketLife’s Cheat Sheet library. If you are looking for some kind of cheat sheets on networking models, IP routing, IPv4 subnetting, NAT, access-lists, VALN, STP, and other topics, this link will be invaluable at the time of your final preparation. All of the cheat sheets are designed and documented in such a way that it is easy and intuitive to review the entire technology at a glance.

The 40 Best Cisco Resources on the Internet. A few years ago, Intense School Resources posted an article aimed at helping every Cisco exam candidate and network professional get the best available online resources. Again, because the article is a few years old, some of the links may be out of date and new ones may have appeared in the meantime. Nevertheless, this is a tremendous collection of worthy online resources that you’ll spend hours exploring.

The article is available in three parts.

This book is loaded with nearly every command needed to cover the CCNA exam, with dozens of configuration examples (including graphical representation) and appropriate output. This book covers all topics of ICND1 100-105, ICND2 200-105, and CCNA 200-125 exams.

What are the Best Practice Exams for the CCNA?

  • Post-exam information

Free e-book: The Big Book of CCNA Study

The Big Book of CCNA Study is one the best ebook to learn all the essential CCNA key points, from OSI models to IP routing to WAN technologies. This ebook contains 44 topical chapters with a practical approach to the key topics. The main element is seven dedicated chapters on “IPv4 Subnetting & VLSM techniques” to master IP schema/subnetting classification. This ebook is contains realistic case studies, practice exercises and tutorials with a brick-by-brick approach.


Although we have provided you with numerous study, preparation and practice options, be aware that this list of resources has only covered a fraction of all the CCNA study materials out on the market. Everyone has different styles of learning and study (some are early birds, others are night owls; some like to study in concentrated chunks, others take frequent breaks to clear their heads), so the important thing to remember is that these study resources are only going to be effective if you pick the ones that complement your natural study and learning patterns. If you only need one or two, try before you buy, if possible.

No matter what you choose, good luck in your studies!
