Question: In a 5G network, when an NF consumer receives an Npcf_AMPolicyAuthorization_Create response indicating a failed AM policy authorization creation from the Policy Control Function (PCF), what happens to the relevant subcounter for the failure cause?
Option 1: The relevant subcounter remains unchanged.
Option 2: The relevant subcounter is reset to zero.
Option 3: The relevant subcounter increments by 1.
Option 4: The relevant subcounter decrements by 1.
Explanation: Upon transmission of an Npcf_AMPolicyAuthorization_Create response indicating a failure, each such message causes the relevant subcounter (specific to the failure cause) to increment by 1, ensuring accurate tracking of failures by their causes for diagnostics and network optimization within the 5G infrastructure.
