Lab: Match error codes to root causes

Error Code Challenge

In this matching exercise you will be given real-world failure scenarios and must identify the correct 5GMM or 5GSM cause code associated with each scenario. This is the kind of rapid pattern-recognition knowledge that separates experienced protocol engineers from beginners. Quick recall of the top cause codes is essential for anyone working in network operations, protocol testing, or troubleshooting roles where every minute of downtime affects thousands of subscribers.
