Diagnose before changing
Start from symptoms and device output. Name the evidence that supports a cause before entering configuration.

CCNA labs:
find the fault, prove the fix.
Turn networking knowledge into a troubleshooting habit. Read the evidence, make a deliberate change, and verify what happened in your browser.
Try the free STP labNo signup or installation. A browser simulation, ready to investigate.
What makes this path different
Practice the reasoning between the commands.
Verify, don’t just finish
A command is not proof. Recheck protocol state and connectivity, then repeat in expert mode without opening the answer.
Know the boundary

A clear next step
Work in order, or revisit the stage that exposed a gap. Read the explanation first, try the lab with guidance, then repeat in expert mode without opening the answer.
Stage 01
Understand the packet
Explain addressing, forwarding, and subnet boundaries.
Before you begin: Start here; no CLI experience needed.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
Stage 02
Make switching predictable
Read VLAN and spanning-tree evidence, then restore the intended Layer 2 path.
Before you begin: Recognise a subnet and a broadcast domain.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
Stage 03
Follow the route
Choose the correct next hop and establish single-area OSPF connectivity.
Before you begin: Understand VLANs and IPv4 addressing.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
Stage 04
Restore essential services
Trace address allocation, translation, time synchronisation, and management failures.
Before you begin: Read a routing table and verify reachability.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
Stage 05
Protect the access layer
Place security controls correctly and prove legitimate traffic still works.
Before you begin: Understand addressing, trunks, and traffic direction.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
Stage 06
Explain automation decisions
Interpret structured data, evaluate AI advice, and distinguish automation tools.
Before you begin: Explain and verify a manual configuration change.
Checkpoint: Explain your reasoning without the answer open. For each lab, name the evidence that proves your fix.
