Question: In a Mission Critical (MC) service over a 5G system, when an MC service client has successfully joined a multicast MBS session, how is the media delivered from the MC service server to the MC service UE(s), according to network mechanisms?
Option 1: Directly via the MC Service Server's Application Layer
Option 2: Via either the 5GC Individual MBS traffic delivery method or the 5GC Shared MBS traffic delivery method, as determined by the network
Option 3: Through a dedicated Unicast Connection established for each UE
Option 4: Using an external Content Delivery Network (CDN)
Explanation: This is correct because, once a UE has joined a multicast MBS session, network mechanisms take over to deliver media. These involve either the Individual or Shared MBS traffic delivery methods of the 5G Core Network (5GC), transparent to the MC service server, ensuring efficient and scalable media distribution to multiple UEs in a multicast scenario.
