This book is a necessary study guide for CCNA exams, written by a well-known authority on Cisco technology. The content of the CCNA exam has changed several times, and the exam objectives written in this book are the latest exam content. This book helps candidates comprehensively review and master new exam content based on the new exam objectives. The book has 11 chapters. In addition to explaining the content that should be mastered, almost every chapter has review questions, written experiments and hands-on experiments, with answers. The optional CD-ROM for this book contains a large number of preparation tools and materials for the new CCNA exam (640-801). In order to help candidates prepare for the Cisco simulation exam, the optional CD-ROM for this book contains a router basic simulator, which introduces the configuration part of Cisco and contains hundreds of actual exam questions, sample simulation questions, and four sets of simulation exam questions. I believe that by studying this book, candidates can successfully pass this exam.
This book is suitable for CCNA#640-801 exam candidates, Cisco network engineering technicians and sales personnel, and teachers and students majoring in computer communications in colleges and universities.
