Question: Under what condition is the MCVideo-5 reference point NOT used for obtaining unicast bearers with appropriate QoS from the EPS by the MCVideo server?
Option 1: When the MCVideo service requires low latency.
Option 2: When there's no operational agreement between the MCVideo service provider and the PLMN operator for direct QoS control.
Option 3: During emergency response situations requiring high-bandwidth video streaming.
Option 4: If the EPS is experiencing congestion and cannot allocate new bearers.
Explanation: The correct answer highlights a condition where the MCVideo-5 reference point isn't utilized, specifically due to the absence of an operational agreement between the MCVideo service provider and the PLMN operator for direct Quality of Service control, crucial for the MCVideo server to manage QoS directly from its domain via the EPS.
