Question: What triggers the increment of the 'Number of parameter update requests' measurement in a 5G network, as per UDM (User Data Management) functionality?
Option 1: Receipt of an Nudm_ParameterProvision_Update request by the UDM from a consumer Network Function (NF), such as the NEF (Network Exposure Function).
Option 2: Transmission of an Nudm_ParameterProvision_Update response by the UDM to a consumer NF, indicating a successful parameter update.
Option 3: Periodic synchronization between UDM and other network functions for data consistency checks.
Option 4: Initialization of a new Packet Data Unit (PDU) session by the User Equipment (UE).
Explanation: The correct answer is based on how parameter update requests are handled in a 5G network. The measurement increases when the UDM receives an Nudm_ParameterProvision_Update request from another NF like NEF, aligning with managing and orchestrating updates within the network. Options 2, 3, and 4 are incorrect as they describe a response to an update, an unrelated maintenance task, or an action related to user data sessions rather than parameter updates.
