HCNA Network Technology Study Guide

HCNA Network Technology Study Guide: The HCNA Network Technology Learning Guide is a learning guide for Huawei’s HCNA certification. It is intended to help readers understand and understand the key points and difficulties in the knowledge of HCNA network technology. The content includes: basic knowledge of network communication, and introduction to Huawei VRP operating system. Ethernet working principle, STP protocol, VLAN principle, IP basic knowledge, TCP and UDP, routing protocol basics, RIP protocol, OSPF protocol, Layer 3 communication between VLANs, link aggregation technology, Smart Link and Monitor Link, DHCP , address translation technology, PPP and PPPoE, network security and network management.

HCNA Network Technology Study Guide 2019

The previously published book “HCNA Network Technology Experiment Guide” is an experimental guide book designed to help readers improve their hands-on skills.

 

Correspondingly, the purpose of the HCNA Network Technology Study Guide is to help readers understand and master the principle knowledge. I hope that readers and friends can combine these two books and get double learning efficiency and learning effects.

 

The HCNA Network Technology Study Guide provides a very detailed and thorough explanation of the key points and difficulties in the knowledge of HCNA network technology. It is especially suitable for readers who are learning and preparing for HCNA.

 

For college students who want to understand the basics of routing and exchange accurately and profoundly, ICT practitioners and network technology enthusiasts, the HCNA Network Technology Learning Guide is also of great value.

  1. An impressive share, I simply given this onto a colleague who was doing a bit evaluation on this. And he the truth is bought me breakfast because I found it for him.. smile. So let me reword that: Thnx for the deal with! But yeah Thnkx for spending the time to debate this, I really feel strongly about it and love reading extra on this topic. If possible, as you change into experience, would you thoughts updating your blog with extra particulars? It is highly useful for me. Large thumb up for this weblog put up!
