Lab: Interface identification challenge

Interface Rapid-Fire Challenge

This rapid-fire challenge tests your ability to quickly identify which interface connects any two network functions in the 5G core. You will be presented with pairs of NFs and must select the correct interface from the options. Speed matters because real-world troubleshooting requires instant recall of the interface map when reading protocol traces and diagnosing connectivity issues. Knowing that the AMF reaches the SMF on N11 or that the AUSF contacts the UDM on N13 should become as automatic as knowing your phone number.
