Key facts

About the 网络基础 certification

网络基础认证为每一位网络、云计算、安全及系统领域的从业者构建坚实的知识体系。本认证厂商中立，从第一性原理出发：讲解 OSI 与 TCP/IP 模型如何分层完成数据传输任务、封装如何将消息逐层打包为段、包和帧，以及每个 PDU 所承载的内容。 你将掌握 IPv4 地址规划与子网划分——CIDR 表示法、子网掩码、网络/广播/主机地址范围，以及将网络切分为子网的计算方法——同时掌握 IPv6 的核心知识。考试内容涵盖 MAC 地址与 ARP、集线器、交换机和路由器的本质区别、以太网与 LAN 基础、VLAN 入门，以及核心应用层协议（HTTP/S、DNS、DHCP、FTP、SSH、SMTP）及其知名端口与套接字。 你还将深入理解 TCP 与 UDP 及三次握手、NAT 与私有地址、默认网关与基础路由、网络拓扑结构、传输介质（铜缆、光纤和无线），以及带宽、延迟和吞吐量等性能术语。本认证最后涵盖实用的故障排除技能（ping 与 traceroute）和安全基础（防火墙与 VPN）。这是迈向路由与交换助理认证的自然起点。

What you will learn

The official 网络基础 study course covers:

  1. How Networks Are Layered: OSI, TCP/IP & Encapsulation — The two reference models, what lives at each layer, and how a message is wrapped into segments, packets and frames.
  2. IP Addressing & Subnetting — IPv4 structure, CIDR and masks, the subnet math, private addressing/NAT and the basics of IPv6.
  3. LAN Devices, Ethernet & VLANs — Hubs vs switches vs routers, how switches learn, Ethernet/LAN basics, and an introduction to VLANs and segmentation.
  4. Transport Layer & Core Protocols — TCP vs UDP and the three-way handshake, ports and sockets, and the everyday protocols: HTTP/S, DNS, DHCP, FTP, SSH, SMTP.
  5. Routing, Performance, Troubleshooting & Security — Default gateways and routing basics, topologies and media, bandwidth/latency/throughput, ping/traceroute, and firewall/VPN fundamentals.
