Furthermore, Cisco publishes its Certification Roadmaps at . I recommend bookmarking that page; it will give you information about Cisco’s yearly certification review process and any scheduled changes coming to the CCNA exam (and Cisco’s other exams).
The first time you read this book, I recommend following the chapters in order. However, it’s important to carefully examine the CCNA exam topics and make sure you know all of them before taking the CCNA exam. This resource should be helpful in that process; if there are any exam topics that you don’t feel confident about, refer to the table to know which chapters you should review.
