Question: What type of data does the Unstructured Data Storage Function (UDSF) support storing and retrieving?
Option 1: Structured data, as defined in 3GPP specifications
Option 2: Both structured and unstructured data
Option 3: Unstructured data, for which the structure is not defined in 3GPP specifications
Option 4: Only metadata related to NF services
Explanation: The UDSF supports storing and retrieving information as unstructured data by any Network Function (NF). This means that the UDSF is designed to handle data for which the structure is not defined in 3GPP specifications, making option 3 the correct answer.
