Question: In an MBMS (Multimedia Broadcast/Multicast Service) context, using FLUTE (File Delivery over Unidirectional Transport) sessions, what is the primary purpose of tracking the 'Object_Loss' metric during a resolution period?
Option 1: To monitor the overall bandwidth utilization of the MBMS client.
Option 2: To evaluate the quality of the received multimedia content.
Option 3: To quantify the number of objects that failed to be delivered to the MBMS client within the session's resolution period.
Option 4: To adjust the transmission rate based on the client's reception capacity.
Explanation: The 'Object_Loss' metric specifically measures the count of objects lost during a FLUTE session's resolution period, directly indicating the delivery failure rate. This metric is crucial for assessing the reliability and efficiency of content distribution in MBMS services.
