Q48 Service Bus Domain 3 · 20–25% of exam

A message fails processing 10 times in a row. Where does Service Bus automatically move it?

  1. A Back to the main queue indefinitely
  2. B To the dead-letter queue (DLQ) (correct answer)
  3. C It is silently deleted
  4. D To an archive topic

Shortcut: Service Bus automatically moves messages to the dead-letter queue after the maximum delivery count (default 10) is exceeded. Applications can then inspect and reprocess DLQ messages.
