 ### Lab 3 - Docker Deployment Validation
 **CRITICAL**: After Docker setup changes, ALWAYS validate full deployment:
-- Test image pulls: `docker pull free5gc/nrf:v3.4.2`
+- Test image pulls: `docker pull free5gc/nrf:v4.2.0`
 - Verify network bridges: `brctl show` (should show docker0 and potentially br-free5gc)
 - **Manual validation**: Deploy core services and verify connectivity between NFs
 - **Check logs**: Each NF should start successfully and register with NRF
