Question: What does the CN-IP-Multicast-Distribution AVP indicate in relation to MBMS user plane data distribution?
Option 1: The type of encryption used for MBMS user plane data.
Option 2: The priority level of MBMS user plane data transmission.
Option 3: The maximum bandwidth allocated for MBMS user plane data.
Option 4: Whether IP multicast distribution to UTRAN should be used for the MBMS user plane data.
Explanation: CN-IP-Multicast-Distribution AVP is an Enumerated type that indicates whether IP multicast distribution of MBMS user plane data to UTRAN should be used. This is crucial in determining how the data will be delivered, which affects network resource allocation and efficiency.
