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.
