Question: What is the purpose of the Nnef_AMInfluence_Create operation in the 5G System (5GS) architecture?
Option 1: To retrieve AM influence data from the UDR.
Option 2: To delete existing AM influence data from the UDR.
Option 3: To authorize and store AM influence data in the UDR, potentially translating GSPI to SUPI and External Group Identifier to Internal Group Identifier.
Option 4: To update the AF Transaction Id in the UDR.
Explanation: The Nnef_AMInfluence_Create operation is used to authorize the request and store the AM influence data in the User Data Repository (UDR), which may involve translating GSPI to SUPI and External Group Identifier to Internal Group Identifier. This operation is crucial for managing access and mobility management (AM) policies in the 5GS architecture.
