What is the Unstructured Data Storage Function (UDSF)?

Answer options

• A. This network function exposes 5G Core Network functionalities available to 3rd parties, so that 3rd party capabilities and events may be securely exposed by the Network Exposure Function (NEF).
• B. This network function is part of data repositories in the Common Data Layer. It stores 3GPP standardized data.
• C. This network function is part of data repositories in the Common Data Layer and in opposition to the UDR, it stores non-standardized – Unstructured – data.
• D. This network function stores or retrieves subscriptions, profiles, and authentication data to or from the data repositories. It offers services to the AMF, SMF, NEF and AUSF using the Service Based Interface.

Correct answer: C

Explanation

The correct answer is C because the UDSF specifically handles non-standardized or unstructured data, distinguishing it from the UDR which focuses on standardized data. Options A and B describe different functions that do not pertain to unstructured data, while D refers to another network function that manages authentication and subscription data.
