Question: In the context of Mission Critical Video (MCVideo) over a telecommunications network, which of the following information flows is NOT specifically identified for an on-network video push in the functional architecture?
Option 1: MCVideo Private Call Request (MCVideo Client → MCVideo Server)
Option 2: MCVideo Call Establishment Acknowledgement (MCVideo Server → UE: User Equipment)
Option 3: MCVideo Private Call Response (MCVideo Server → MCVideo Client)
Option 4: MCVideo Group Call Setup Notification (MCVideo Server → Multiple MCVideo Clients)
Explanation: The correct answer is Option 2 because the provided context specifically mentions information flows related to private call requests and responses between the MCVideo client and server. However, 'MCVideo Call Establishment Acknowledgement (MCVideo Server → UE: User Equipment)' is not listed among these specified flows for on-network video push, introducing an unmentioned element (UE) and message type.
