PractiCLI
Built for Cisco CCNA 200-301

CCNA lab online — practice the Cisco CLI in your browser

Configure routers and switches on true-to-life command lines, break realistic faults and fix them, and drill performance-based questions — all in a browser tab. No install, no VM, no firmware images. It even runs on a Chromebook.

Passing the CCNA 200-301 takes two things: understanding the theory, and being fast and confident at the command line. Videos build the first — only hands-on repetition builds the second. PractiCLI gives you a faithfully simulated Cisco IOS command line, not a drag-and-drop simulator, where supported show and configure commands behave the way they do on the exam and on the job.

The 200-301 blueprint

What you practice in the CCNA lab

Every core topic, built from scratch, verified with real output, and broken on purpose so you learn to fix it.

Routing

Static routes, OSPF single-area, default routes and route verification with show ip route.

Switching

VLANs, 802.1Q trunking, access ports and inter-VLAN routing (router-on-a-stick and SVIs).

First-hop redundancy

HSRP active/standby, priorities and failover you can watch happen live.

Addressing & services

NAT and PAT, DHCP, DNS, NTP and the IP services the exam expects you to configure.

Security

Standard and extended ACLs, port security and basic device hardening.

Verification & troubleshooting

Reading show output, isolating the fault, and proving the fix end to end.

The method

Three ways to train, not just a sandbox

A path from guided configuration to diagnosing a fault you can't yet see — the way the exam and the job actually test you.

01 · Guided labs

Build it, step by step

Scenarios with clear objectives and automatic checks: you configure, you verify, and the lab confirms whether the result is correct.

02 · Fault troubleshooting

Break it, fix it

A realistic fault is injected — a missing route, a VLAN mismatch, a broken ACL — a ticket opens, and it closes only when you actually fix it.

03 · PBQ practice

Pass the exam tasks

Performance-based questions in exam style: not multiple choice, but tasks to carry out on the device, with scoring.

Time-sensitive · exam change

CCNA 200-301 is changing on 3 February 2027

Cisco retires the CCNA 200-301 v1.1 exam on 2 February 2027 and introduces v2.0 the next day, with more weight on hands-on skills. The surest way to prepare for a more practical exam is to spend more time on the command line — reproducing configurations and faults until they are automatic. That is exactly what PractiCLI is built for.

Honest comparison

Why not just Packet Tracer?

Packet Tracer is a capable Cisco simulator with its own CLI and topology builder. The difference is scope: multi-vendor coverage, injected faults and exam-style scoring.

Packet Tracer

  • Desktop app — download and install
  • Cisco devices only — no FortiGate, MikroTik or Linux
  • No injected faults or troubleshooting tickets
  • No performance-based (PBQ) exam tasks
  • Built for topology design, not multi-vendor practice

PractiCLI

  • The command line, the way you'll work
  • One plan, 10+ vendors and platforms
  • 400+ break/fix faults with a ticket to close
  • 900+ PBQ-style questions with scoring
  • Runs in the browser, even on a Chromebook

PractiCLI focuses on the command line, adds break/fix troubleshooting and exam-style questions, and the same plan grows with you well beyond CCNA. See simulation vs emulation for how the engine works.

// FAQ

CCNA lab — common questions

Do I need to install anything?
No. The CCNA lab opens in a browser tab. There is no VM, no firmware image and no special hardware requirement, so it works on light machines and Chromebooks too.
Is this a good Packet Tracer alternative for CCNA?
Yes. You work on the command line with injected faults, troubleshooting tickets and PBQ-style scoring, and the same plan also covers FortiGate, MikroTik, Linux and more.
Does it cover the CCNA 200-301 topics?
The CCNA track covers routing and switching, VLANs and trunking, OSPF, HSRP, NAT, ACLs and IP services, with guided labs, fault troubleshooting and performance-based (PBQ) practice that mirror the exam style.
Will it help me prepare for the new CCNA 200-301 v2.0 exam?
Yes. CCNA 200-301 v2.0 starts on 3 February 2027 with more emphasis on hands-on skills, and PractiCLI is built for exactly that: repeating real configurations and faults on the command line until they are automatic.
