There are many resources available for the future network engineer but there are two books I always recommend to anyone wanting to tackle the CCNA. Both are from Cisco Press and authored by Wendell Odom who does a fantastic job in getting you all the information you need to pass the CCNA.
Depending on how you are going to take the exam you have two options, composite or separate exams.
If you’re studying for the CCNA Routing and Switching composite, 200-120 exam then all you need is CCNA Routing and Switching 200-120 Official Certification Guide.
If you’re going to split the exams in two, which is what I did, then you need the following books:
All three books are updated for the latest redesigned CCNA exam.
Why Cisco Press books? They follow the exam objectives. It’s easy to go through while following the blueprint. The CCNA books come with pre-chapter quizzes to test your knowledge of each topic. I recommend taking the pre-chapter quizzes after reading through the material to find out where your weak areas are.
At the end of each chapter there are exercises to reinforce what you just read. Additionally, you are given memory tables of which you should memorize for the exam.
The extra material is aimed at helping you master the topics needed to pass the CCNA exam. The books are very helpful and should be the core part of your study plan.
