Question: What is a key aspect of the consistency control feature in MBMS metadata syntax, as per 3GPP standards for Multimedia Broadcast/Multicast Service (MBMS)?
Option 1: It ensures metadata fragments are only delivered over secure bearers.
Option 2: It guarantees simultaneous delivery of all metadata fragments to all receivers.
Option 3: It relies on the transport layer for versioning and expiry management.
Option 4: It maintains consistency of metadata versions between senders and receivers, regardless of the transport and bearer used.
Explanation: This option correctly highlights the independence of consistency control from the underlying transport and bearer mechanisms, ensuring that metadata versions remain consistent across all parties involved in the MBMS communication. This is crucial for reliable and coherent data exchange in multimedia broadcast and multicast scenarios, where synchronization and version control are paramount.
