Learn the CCNA® by doing
Pick how you want to practice: type real Cisco IOS on the live CLI, download a Packet Tracer topology, or step through an interactive simulator. Each opens a hub with every lab of that kind in one place. Free, in your browser, nothing to install.
Configure & troubleshoot on real IOS
25 build tasks (start from a blank device and configure to spec) and 26 fix tasks (diagnose one realistic fault). Real Cisco IOS syntax, per-device CLI, objectives grade live as you type.
Build it in Packet Tracer
Download a ready-made .pkt topology and configure it in Cisco Packet Tracer: VLANs, OSPF, ACLs, NAT, STP, security and more, CCNA through CCNP.
Watch it work, step by step
Move the subnetting slider, step OSPF Down→Full, send a packet through an ACL, tag a frame across a trunk. Each with a built-in quiz and CCNA-canonical scenarios.
