Question: What is the primary function of the Unified Data Repository (UDR) in the 5G System?
Option 1: To manage and orchestrate Network Functions (NFs) across different PLMNs.
Option 2: To provide a centralized platform for charging and billing of 5G services.
Option 3: To store and retrieve subscription data, policy data, and structured data for exposure to authorized NF service consumers.
Option 4: To handle mobility management and session establishment for UEs.
Explanation: The Unified Data Repository (UDR) is a critical component of the 5G System that provides a centralized storage and retrieval mechanism for various types of data, including subscription data, policy data, and structured data. This allows authorized NF service consumers to access and utilize this data in a secure and efficient manner.
