Question: In the context of Generic Bootstrapping Architecture (GBA) with Service-Based Interfaces (SBI), which reference point connects an SBI-capable Bootstrapping Server Function (BSF) to the Unified Data Management (UDM) entity?
Option 1: N65 - Reference point between BSF and Home Subscriber Server (HSS)
Option 2: N68 - Reference point between BSF and UDM
Option 3: N66 - Reference point between BSF and Network Application Function (NAF)
Option 4: N67 - Reference point between HSS and UDM
Explanation: This question requires understanding of the Generic Bootstrapping Architecture (GBA) and its integration with Service-Based Interfaces (SBI). The correct answer, N68, is specifically identified as the reference point that enables communication between an SBI-capable Bootstrapping Server Function (BSF) and the Unified Data Management (UDM) entity. This connection is crucial for bootstrapping processes that rely on user data managed by the UDM. The other options are incorrect because N65 relates to BSF and HSS interaction, N66 involves BSF and NAF, and there's no mention of a reference point designated as N67 in this context.
