  2. B.Service Bus message deferral with retained retrieval information
  3. C.An Event Hubs checkpoint advanced beyond the message
  4. D.Service Bus scheduling of an entirely new message as the only possible approach
Show the answer and explanation

✓ Correct answer

  • Service Bus message deferral with retained retrieval information

Deferral retains a received message for later retrieval once prerequisites exist. Scheduling controls initial availability and is a distinct mechanism, Receive and Delete does not retain recoverable work, and advancing a stream checkpoint is not deferred Service Bus message retrieval.
