Question: What is the primary purpose of the UAE_C2OperationModeManagement API in the context of Uncrewed Aerial System (UAS) communications?
Option 1: To establish a direct link between the UAS application server and UAV User Equipment (UE) for real-time video transmission.
Option 2: To manage authentication protocols for secure access to UAS operational data.
Option 3: To facilitate the exchange of Command and Control (C2) operation mode configurations between the UAS application server and UAE server, including receiving notifications of selected C2 communication modes from UAS UEs.
Option 4: To optimize network resource allocation for multiple UAVs operating within the same airspace.
Explanation: The correct answer is Option 3 because the UAE_C2OperationModeManagement API enables communication between the UAS application server and the UAE server to send C2 operation mode configurations and receive notifications from UAS User Equipment about selected C2 modes, ensuring efficient and safe UAS operation within a managed airspace.
