Question: What is the purpose of the "Validity time" input in the Nudsf_UnstructuredDataManagement_Update service operation?
Option 1: To specify the duration for which the updated data is stored in the UDSF.
Option 2: To indicate when the NF service consumer intends to retrieve the updated data from the UDSF.
Option 3: To determine the frequency at which the NF service consumer will be notified about updates to the data.
Option 4: To define the time zone for the Data Identifier.
Explanation: The "Validity time" input in the Nudsf_UnstructuredDataManagement_Update service operation is used to specify the duration for which the created or updated data is valid. When this validity time has expired, the NF service consumer is notified and the data is removed from the UDSF. This ensures that outdated data does not remain stored unnecessarily.
