Question: What is the granularity of a 5GS DetNet node for each network instance or DNN/S-NSSAI?
Option 1: Per UE
Option 2: Per PDU Session
Option 3: Per UPF
Option 4: Per Network Slice
Explanation: According to the text, "The granularity of the 5GS DetNet node is per UPF for each network instance or DNN/S-NSSAI." This indicates that a 5GS DetNet node is defined at the level of an individual UPF (User Plane Function) for each network instance or DNN/S-NSSAI.
