Question: What factors may be considered by an NF consumer, such as NWDAF, for AF discovery and selection in the MNO domain?
Option 1: Only the S-NSSAI corresponding to an AF.
Option 2: Only the DNN corresponding to an AF.
Option 3: One or multiple combinations of the S-NSSAI and DNN corresponding to an AF, Supported Application Id(s), Event ID(s) supported by an AF, and Internal-Group Identifier.
Option 4: Only the Event ID(s) supported by an AF.
Explanation: The correct answer is Option 3 because, according to the 3GPP TS 23.501 specification, multiple factors may be considered for AF discovery and selection, including one or multiple combinations of the S-NSSAI and DNN corresponding to an AF, Supported Application Id(s), Event ID(s) supported by an AF, and Internal-Group Identifier. This allows the NF consumer to select an appropriate AF instance based on various criteria, ensuring that the required input data is obtained for analytics generation.
