CCNA 200-301 preparation
Learn the CLI by using the CLI.
Mind Goblin is a browser-based Cisco lab. Configure real topologies, break them, and get graded on the running-config you produced — no virtual machines, no images to download, no licence to buy.
R1# configure terminal R1(config)# interface GigabitEthernet0/0 R1(config-if)# ip address 10.0.0.1 255.255.255.0 R1(config-if)# no shutdown R1(config-if)# exit R1(config)# router ospf 1 R1(config-router)# network 10.0.0.0 0.0.0.255 area 0 R1(config-router)# end R1# show ip ospf neighbor
What you get
High-fidelity IOS simulator
A real command parser with modes, tab completion, context help, and platform profiles for Catalyst switches and Catalyst 8000V routers. Wrong commands fail the way they fail on real gear.
Graded hands-on labs
Over two hundred lab scenarios across network fundamentals, access, IP connectivity, IP services, security, and automation — each graded against the configuration you actually produced.
Exam-style practice
Topic-weighted question banks covering the full CCNA blueprint, with review sessions that target the objectives you keep missing.
Progress that means something
Mastery tracking per objective, a study plan that adapts to your exam date, and a readiness picture built from graded work rather than page views.
