Features: CCNA is a fundamental certification from Cisco Systems, primarily aimed at small and medium-sized network administrators. With the continuous development of network technology, new technologies and applications emerge constantly. To adapt to this evolution, Cisco updated the CCNA exam in 2002, incorporating content previously covered in CCNP while removing some basic material. This book covers all the content of the new CCNA exam. The author recommends reading the chapters in order, though each chapter is relatively independent. Written by instructors teaching CCNA certification courses, the book provides detailed explanations of key and difficult points in the curriculum, as well as new exam changes. It primarily includes the following content: basic networking knowledge, the concept of routing and the working principles of routing protocols, Cisco router configuration methods, access control lists, methods and techniques for network troubleshooting, the working principles and configuration of switches, and wide-area network technologies (including concepts and configuration methods for ISDN and PPP verification, Frame Relay, and network address translation, among others). This book is suitable for CCNA exam takers, small and medium-sized network administrators, and network technicians, as well as serving as a textbook for relevant technical training courses.
