Question: When updating an existing MBS User Data Ingest Session Status Subscription at the Network Exposure Function (NEF), which HTTP method is used by an Application Function (AF) and what is included in the request body?
Option 1: HTTP POST with MBSUserDataIngStatSubscPatch data structure
Option 2: HTTP PUT with MBSUserDataIngStatSubsc data structure for update, or HTTP PATCH with MBSUserDataIngStatSubscPatch for modification
Option 3: HTTP GET with no request body for both update and modification
Option 4: HTTP DELETE with MBSUserDataIngStatSubsc data structure for updating the subscription
Explanation: This requires understanding of AF-NEF interaction to manage MBS User Data Ingest Session Status Subscriptions. The correct answer reflects the procedure's specification: HTTP PUT with MBSUserDataIngStatSubsc for updates, and HTTP PATCH with MBSUserDataIngStatSubscPatch for modifications, highlighting the importance of using appropriate HTTP methods for different operations in telecom network management.
