Question: In a 5G System utilizing RESTful principles, what is the primary role of Hypermedia (as per HATEOAS) during interactions between an NF Service Consumer and Producer?
Option 1: To authenticate all NF Service Consumers before allowing resource access.
Option 2: To encrypt data exchanged between the NF Service Consumer and Producer.
Option 3: To provide control state options, enabling the application to transition between states by selecting from embedded hypermedia markups.
Option 4: To log all interactions for billing purposes.
Explanation: According to HATEOAS, hypermedia is crucial for modeling application state transitions and describing application protocols. It embeds control states in resource representations, allowing NF Service Consumers to choose the next interaction, driving the application from one state to another.
