Question: In a Multimedia Broadcast/Multicast Service (MBMS) deployment with multiple BM-SCs, what happens to outstanding file repair procedures when an updated in-band Associated Delivery Procedure Description (ADPD) fragment no longer includes a `postFileRepair` element?
Option 1: The MBMS client continues the outstanding file repair procedures with the previously set timer parameters.
Option 2: All outstanding file repair procedures for the service are cancelled.
Option 3: The MBMS client pauses the outstanding file repair procedures until a new `postFileRepair` element is received.
Option 4: The system automatically generates a new `postFileRepair` element to continue the procedures.
Explanation: According to the specifications for handling multiple ADPD fragments in MBMS deployments, when an updated ADPD fragment no longer includes a `postFileRepair` element, all outstanding file repair procedures for the service are cancelled. This ensures consistency and prevents potential conflicts or misunderstandings by the MBMS client across different BM-SC coverage areas.
