Question: What is the correct structure for the root URI of the Home Subscriber Server (HSS) API for interworking with Unified Data Management (UDM)?
Option 1: {apiRoot}/hss/<apiVersion>/
Option 2: {apiRoot}/nhss-ee/v2/
Option 3: {apiRoot}/nhss-ee/v1/
Option 4: https://default/nhss-ee/<apiVersion>/
Explanation: According to specifications for HSS services, the correct root URI structure is defined as {apiRoot}/{apiName}/{apiVersion}/, where {apiName} must be set to 'nhss-ee' and {apiVersion} to 'v1' for compatibility and adherence to the standardized API interface for effective interworking with UDM.
