Question: When an Application Function (AF) sends a collected UE Data Report to the Network Exposure Function (NEF), what HTTP method and URI structure does it use for the request?
Option 1: HTTP GET to `{apiRoot}/3gpp-data-reporting/v1/sessions/{sessionId}/query`
Option 2: HTTP POST to `{apiRoot}/3gpp-data-reporting/v1/sessions/{sessionId}/report`
Option 3: HTTP PUT to `{apiRoot}/3gpp-data-reporting/v1/sessions/{sessionId}/update`
Option 4: HTTP DELETE to `{apiRoot}/3gpp-data-reporting/v1/sessions/{sessionId}/remove`
Explanation: The correct answer is Option 2 because, according to the specified procedure for sending collected UE Data Reports from an Application Function (AF) to the Network Exposure Function (NEF), the AF must utilize an HTTP POST request. This POST request targets a specific URI structure, which includes the session ID and is designated for reporting, hence `{apiRoot}/3gpp-data-reporting/v1/sessions/{sessionId}/report`. This method and URI structure are specifically defined for the purpose of submitting Data Reports, ensuring efficient and standardized communication between the AF and NEF within the 5G system's network exposure framework.
