Question: When an Application Function (AF) updates an existing Individual ECS Address Provision Configuration, what type of HTTP message is sent to the Network Exposure Function (NEF), and what is included in its body?
Option 1: HTTP PATCH message with EcsAddressProvision data type
Option 2: HTTP PUT message with EcsAddressProvision data type
Option 3: HTTP POST message with SpatialValidityCond data structure
Option 4: HTTP DELETE message with TgtUe information
Explanation: When updating an existing Individual ECS Address Provision Configuration, the AF needs to send a request that overwrites all properties of the existing resource. An HTTP PUT message is used for such updates, with its body including the updated EcsAddressProvision data type to specify the changes, enabling the NEF to modify the existing resource via the Nudm_ParameterProvision service.
