CCNA — Networking Fundamentals and Cisco IOS
À propos du cours
Welcome to the free first step of the CCNA 200-301 track. This level 1 course lays the groundwork you need to understand how an enterprise network actually works and how you configure it with Cisco equipment.
You start from scratch: what a network is for, the OSI and TCP/IP models, the hardware (switches, routers, cables), then your first hands-on time with the Cisco IOS operating system. Every concept is backed by labs built in Cisco Packet Tracer, the free official simulator, so you are typing real commands from lesson one.
By the end you will be able to configure a switch and a router, secure their access, address a network in IPv4 and IPv6, break it into subnets and verify connectivity. This is the shared foundation before you move on to routing, advanced switching and security later in the CCNA track.
