Question: What triggers the increment of the 'Number of SM policy authorization deletion requests' measurement in a 5G network?
Option 1: Successful transmission of an Npcf_PolicyAuthorization_Delete response to an NF consumer.
Option 2: Receipt of an Npcf_PolicyAuthorization_Delete request by the PCF from an NF consumer (e.g., Application Function - AF).
Option 3: A timer expiration for pending policy authorizations at the PCF.
Option 4: Manual intervention by a network administrator to clear policy authorizations.
Explanation: The measurement 'Number of SM policy authorization deletion requests' increments upon the PCF receiving a deletion request (Npcf_PolicyAuthorization_Delete) from another network function consumer, such as an Application Function (AF), highlighting key interactions for effective policy control in 5G networks.
