You use Azure Redis Cache to avoid reprocessing expensive image-analysis uploads. To minimize metadata loss during a regional outage, which two configuration actions should you perform on the Azure Redis instance?

AOF (Append Only File) persistence logs every write operation received by the Redis server. This ensures that if the server restarts, Redis can reconstruct the dataset by replaying the logged operations, minimizing data loss even during unexpected outages. RDB (Redis Database Backup) persistence takes periodic snapshots, meaning data written between snapshots could be lost. Configuring a second storage account for persistence provides redundancy. If the primary storage account or region becomes unavailable, the persistence file (AOF or RDB) can still be accessed from the secondary location, enhancing disaster recovery capabilities. Setting backup frequency to the minimum value is not a direct Redis configuration for persistence and doesn't inherently provide cross-regional redundancy.
