Q4 Event Hubs Domain 3 · 20–25% of exam Priority · Real Exam

An analytics job must reprocess the last 3 days of events after a bug fix. What makes this possible?

  1. A Dead-lettering
  2. B Reading from an earlier offset or timestamp within the retention window (correct answer)
  3. C Re-sending from producers
  4. D Capture only

Shortcut: Because the log is retained rather than consumed destructively, a processor can reset its checkpoint and replay from any offset or enqueued time still inside the retention period.
