Question: Which field in the Monitoring Event Report Data container is used to uniquely identify a Monitoring Request globally, when combined with another identifier?
Option 1: SCEF Reference ID (when combined with SCEF Id)
Option 2: Chargeable Party Identifier
Option 3: Monitored User
Option 4: Monitoring Event Report Number
Explanation: The correct answer is Option 1 because the SCEF Reference ID, when paired with the SCEF Id, serves as a globally unique identifier for the Monitoring Request. This ensures that each monitoring event can be distinctly traced back to its originating request across different SCEFs (Service Capability Exposure Functions), preventing confusion or overlap between various requests and their associated reports.
