Learn the CCNA® by doing
Don't just read about networking — practice it. Interactive simulators and live CLI labs where you type real Cisco commands and watch what happens. Free, in your browser, nothing to install.
Fix a broken network — like the real exam
One realistic fault, only the symptom given. Diagnose it with real show commands on a live console and fix it — often more than one valid way. The full command engine is available, so figuring out the right command is part of the practice.
Type real Cisco commands
Configure VLANs, trunks and more on a simulated device. Abbreviations, Tab-completion and show commands all work — and the objectives tick off live as you get them right.
Watch it work, step by step
Move the subnetting slider, step OSPF from Down to Full, send packets through an ACL, tag a frame across a trunk — each with a built-in practice quiz and CCNA-canonical scenarios.
A timed, full-length mock exam
Blueprint-weighted questions — multiple choice, multiple-response, matching and drag-and-drop — on the clock and scored by exam domain so you know exactly where you stand. Free, no sign-up.
