Build exam confidence through practice
Start with a broken OSPF neighbour, follow the guided correction, and verify the repair. Build the diagnostic habits your exam expects, without building your own lab environment.
Start with a focused CCNA troubleshooting lab.
Six practical CCNA scenarios to build your diagnostic instincts. Browse the complete catalog when you want a different topic.
CCNA · 200-301
FreeSpanning Tree: Root Bridge Election
A free, ungated example lab: a misconfigured root bridge sends traffic the long way round. No email required to see the fix.

FreeVLANs, Trunking & Spanning Tree
802.1Q trunks and native VLANs, STP root election, and inter-VLAN routing on a switched campus.

CCNA · 200-301
FreeOSPF Neighbor Down: Area Mismatch
Two routers ping each other fine across a direct link, but their OSPF adjacency refuses to form. Work it from Layer 3 up to the routing protocol.

CCNA · 200-301
FreeStatic Route: Wrong Next Hop
A static-route command names an unreachable next hop, so its prefix never reaches the routing table. Inspect the configuration, repair it, and prove the remote LAN is reachable.

CCNA · 200-301
FreeAccess Control Lists: Configuring & Verifying
PC1 can't reach a server through R1, and the router is sending back an explicit deny, not a timeout. The permit entry meant to allow it is right there in the ACL.

FreeEtherChannel: LACP Mode Mismatch
A two-link uplink should bundle, but each member remains individual. Compare both ends, correct the LACP mode, and verify the port channel.

Start with a free Guided Lab above. When you need a different study format, choose self-directed virtual time or a focused question set.
Guided Labs
Structured, step-by-step scenarios in a broken environment. Several are completely free to try end to end; the rest unlock with an email or a Learning Pass.
- Learn one concept at a time
- Real CLI output, worked solutions
- Several labs are free end to end, no email needed
Virtual Labs
Dedicated time on the real gear, from a single Cisco pod to the full Catalyst Center. You drive it yourself, for the window you book.
- Full certification-level pods
- Exclusive, dedicated access
- Book by the session or go persistent
Exam Questions
Multiple-choice practice questions covering every major CCNA 200-301 topic. Test yourself cold or get instant feedback on every answer.
- 279 questions across 30 topics
- Guided mode explains each answer
- Expert mode scores you at the end
How It Works
Reserve your session now; your access details arrive five minutes before it starts.
1. Book Your Session
- Choose an available session on the schedule page
- Complete payment to confirm your reservation
- Instant booking confirmation sent to your email
2. Receive Access Details
- 5 minutes before your session starts, you receive an email
- Email contains your unique lab URL, username, and password
- Credentials are generated fresh for every session, never reused
3. Open the Lab Portal
- Click the link in your email, which opens directly in your browser
- Log in with the credentials provided. No software to install
- The browser-based PNETLab console gives you full access to your lab nodes
4. Console In & Practice
- Power on your topology: Cisco Catalyst, Palo Alto, Fortinet, etc.
- Console directly into devices from the browser. No SSH client needed
- You get a 15-minute warning before your session ends
Technical access details
What you connect to
A dedicated PNETLab web portal, accessed securely over HTTPS. No VPN is required for browser-based console access.
Session security
Your credentials expire the moment your session ends. The lab is wiped and reset before the next user connects.
Optional: packet capture
Install the Cloudflare WARP client (Zero Trust) to route your session locally and capture live traffic with Wireshark.
Session extension
If the next session is free, extend by 6 hours with one click directly from the lab portal, charged at the standard rate.
Browser compatibility
Use Chrome, Firefox, or Safari. If Brave blocks a topology interaction, disable Shields for the lab URL or switch browsers.
