Question: In an MCData content server utilizing MBMS for file distribution, what are the two defined ingest modes for transferring files to the Broadcast Multicast Service Center (BM-SC) over the xMB interface?
Option 1: Synchronous and Asynchronous
Option 2: Push and Pull
Option 3: Unicast and Multicast
Option 4: Online and Offline
Explanation: The correct ingest modes for transferring files from an MCData content server to the BM-SC over the xMB interface, as applicable in the context of Multimedia Broadcast/Multicast Service (MBMS) for targeted file distribution, are indeed "Push" and "Pull". - **Push** mode involves the MCData server initiating the transfer by 'pushing' the file to the BM-SC. - **Pull** mode involves the BM-SC requesting (pulling) the file from the MCData server for distribution. This flexibility allows for implementation-specific choices based on system design and operational preferences.
