Question: In an integrated deployment scenario, what is a possible relationship between the Service Capability Exposure Function (SCEF), Network Exposure Function (NEF), and Common API Framework (CAPIF) core function in a 3GPP Northbound API architecture?
Option 1: The SCEF and NEF must be deployed as separate entities, each interacting with multiple CAPIF core functions.
Option 2: The SCEF, NEF, and CAPIF core function are always standalone components, never integrated.
Option 3: The SCEF and NEF can be integrated with a single CAPIF core function to offer their respective service APIs.
Option 4: Integration is only possible between the SCEF and NEF, excluding the CAPIF core function.
Explanation: This correct answer reflects an understanding of flexible deployment models in 3GPP Northbound API architectures. Integrating the SCEF (handling service capability exposure) and NEF (managing network exposure) with a single CAPIF core function (providing a common API framework) can streamline API invocation processes for external applications, enhancing efficiency and reducing complexity in telecom networks. This setup is particularly beneficial for operators seeking to simplify their infrastructure while maintaining robust API-based service offerings.
