  6. SDN Troubleshooting — Network Controller, SLB, gateway
  7. Deployment Failure Diagnosis — common errors and resolutions
  8. When and How to Engage Microsoft Support

Hands-on

Lab/Demo: Guided break-fix scenarios. Instructor injects failures (disk pull, network unplug, agent stop) and learners diagnose using documented tools.
