Question: In MBMS (Multimedia Broadcast/Multicast Service), under what condition may a UE (User Equipment) receive media resources over both broadcast and unicast modes, in addition to the service provider's policy?
Option 1: When the UE is out of MBMS broadcast coverage area.
Option 2: Based on user preference when the UE is within MBMS broadcast coverage.
Option 3: Only if the service provider has disabled unicast mode for that specific resource.
Option 4: If the media resource is not available in the broadcast version.
Explanation: This option is correct because, according to specifications, when a UE is within MBMS broadcast coverage and based on user preference, it can receive media resources delivered over both broadcast (for primary content) and unicast (for additional resources). This setup allows for a hybrid delivery method leveraging the strengths of both broadcast (efficient for widely consumed content) and unicast (suitable for personalized or additional content) modes.
