Q40 Redis Domain 2 · 25–30% of exam Priority · Real Exam

Which persistence option in Azure Managed Redis provides the smallest data-loss window?

  1. A RDB snapshots every 60 minutes
  2. B AOF (append-only file) persistence (correct answer)
  3. C No persistence
  4. D Export to blob storage weekly

Shortcut: AOF logs each write operation, so recovery loses at most the last second or so. RDB snapshots lose everything written since the previous snapshot.
