Question: When an Application Function (AF) initiates an HTTP POST request to the Network Exposure Function (NEF) for creating a new '5G LAN Parameters Provision Subscription', what additional parameters may be provisioned if the 'GMEC' feature is supported?
Option 1: Only LPI parameters
Option 2: Only ECS Address information
Option 3: Only Network Parameter Configuration
Option 4: All of the above (LPI parameters, ECS Address information, Network Parameter Configuration)
Explanation: According to the specified telecom protocol for 5G LAN parameter provisioning, when the 'GMEC' feature is supported by the NEF, the AF can provision additional parameters including LPI for precise location services, ECS Address information for enhanced communication routing, and Network Parameter Configuration for customized network settings. Thus, all these options are correctly included when the 'GMEC' feature is enabled.
