Question: What is the primary purpose of measuring the number of stored inactive UE (User Equipment) contexts in a RAN (Radio Access Network) node?
Option 1: To optimize handover procedures between gNBs (next-generation Node Bs)
Option 2: To provide insight into memory consumption for OAM (Operations, Administration, and Maintenance) performance observability
Option 3: To enhance the security of inactive UE connections against potential cyber threats
Option 4: To improve the quality of service for active UE sessions by reallocating resources
Explanation: Measuring the number of stored inactive UE contexts is crucial for understanding memory usage in a RAN node to store information about currently non-active UEs. This measurement is intended for OAM performance observability, focusing on network resource utilization (specifically, memory), aligning with Option 2.
