Learn the CCNA® by doing
Pick how you want to practice — fix a broken network, build a lab in Packet Tracer, 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.
Fix a broken network
One realistic fault, only the symptom given. Diagnose it with real show commands on a live console — and there’s often more than one valid fix, just like the exam.
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.
