Question: What are the primary capabilities of the Authorization Function in a Common API Framework for 3GPP Northbound APIs?
Option 1: Receiving authorization from the resource owner and providing the API invoker with necessary authorization information to access resources.
Option 2: Validating API requests and managing resource allocation without external authorization input.
Option 3: Encrypting data transmissions between the API invoker and the resource owner's resources.
Option 4: Handling billing and subscription services for API usage.
Explanation: The correct answer, Option 1, accurately reflects the primary capabilities of the Authorization Function as defined in the context of 3GPP Northbound APIs. These capabilities are crucial for ensuring that access to resources is properly managed and secured, highlighting the function's role in authentication and permission granting within telecom networks. Options 2, 3, and 4 are incorrect because they describe functions unrelated to the primary purpose of the Authorization Function in this specific context, such as internal validation, data encryption, and financial management, respectively.
