Foreword
Huawei is one of the leading ICT solution providers worldwide. Our vision is to enrich life through communication, and it is with this vision that we are able to leverage our ICT technologies and experience to help everyone bridge the digital divide and become a part of the information society so that all may enjoy the benefits of ICT services. We endeavor to popularize ICT, facilitate education, and cultivate ICT talents, providing people with the tools necessary to build a fully connected world. This book is a study guide for Huawei HCNA certification. It is the culmination of efforts by Dr. Yonghong Jiang and his writing team. Dr. Jiang is a senior technical expert in Huawei and has worked with us for over 10 years. Before joining Huawei, Dr. Jiang gained many years of teaching experience in both domestic and international universities. He therefore has a deep understanding of how knowledge can be taught and mastered. Logic is important for explaining principles, as too is the accuracy of information—the very essence of this is embodied in HCNA Networking Study Guide. I truly believe it is a must-have book for those who intend to learn HCNA network technologies. March 2016
