Question: Where can congestion mitigation for RAN user plane congestion management be performed?
Option 1: Only in the Radio Access Network (RAN)
Option 2: Only in the Core Network (CN)
Option 3: In both the Radio Access Network (RAN) and the Core Network (CN), or in a combined way
Option 4: Neither in the Radio Access Network (RAN) nor in the Core Network (CN)
Explanation: The correct answer is Option 3 because congestion mitigation for RAN user plane congestion management can be performed in both the Radio Access Network (RAN) and the Core Network (CN), or in a combined way, allowing for flexible and effective management of user plane traffic.
