Question: What is the primary goal of the mechanisms provided by the 5G system for UEs returning from a hosting network to their home network in a short timeframe?
Option 1: To prioritize user plane traffic over control plane traffic
Option 2: To mitigate overload and prevent outages on both user and control planes
Option 3: To enforce temporary rate limiting on all returning UEs
Option 4: To automatically trigger a network-wide congestion control
Explanation: The correct answer aligns with the requirement that the 5G system must provide mechanisms to mitigate overload (on user and control planes) caused by a large number of UEs returning in a short period and minimize the impact on UEs' communication, specifically preventing outages, ensuring smooth network operation and maintaining service quality for all users.
