Lab: End-to-end troubleshooting challenge

Full Troubleshooting Simulation

This final lab combines everything you have learned in Level 5 into a complete troubleshooting workflow. You receive a user complaint, must identify which 5G procedure is involved, examine the multi-interface protocol trace, find the specific error point, decode the cause, and propose the correct fix. The scenarios span all five modules — registration failures, PDU session issues, handover problems, paging failures, and error handling. This simulates the day-to-day work of a 5G protocol engineer in a production network.
