Question: Where can the Content Provider/Multicast Broadcast Source function, which interacts with the BM-SC for MBMS services, potentially reside in relation to an operator's network?
Option 1: Exclusively within the operator's network, for security reasons.
Option 2: Only outside the operator's network, to ensure third-party neutrality.
Option 3: Either within the operator's network or provided from outside the operator's network, depending on the arrangement.
Option 4: This is solely determined by the BM-SC's configuration and not variable.
Explanation: The correct answer reflects the flexibility in the deployment of the Content Provider/Multicast Broadcast Source function. It can be integrated within the operator's network for tighter control or provided externally, possibly by a third-party content provider, to leverage external resources or expertise without compromising service delivery.
