Question: In Multimedia Broadcast/Multicast Service (MBMS) deployments, what types of bearers may be utilized alongside MBMS bearers to efficiently deliver application data for MBMS user services?
Option 1: Point-to-Point (PTP) bearers and Dedicated Bearers
Option 2: Only MBMS bearers with enhanced QoS
Option 3: Broadcast Bearers and Unicast Bearers exclusively
Option 4: LTE-Uu Bearers as an alternative
Explanation: The correct answer, Option 1, reflects the understanding that MBMS user services can leverage both **Point-to-Point (PTP) bearers** for individualized or interactive content and **MBMS bearers** for broadcast/multicast efficiency. This combination supports a wide range of applications with varying requirements for data delivery. Dedicated Bearers are also implied in this context as part of the broader bearer management strategy, enhancing the efficiency of application data delivery. The other options are incorrect because they either limit the bearer types too narrowly (Options 2 and 3) or introduce unrelated bearer types (Option 4).
