You are building a web application that performs image analysis on user photos and returns metadata containing objects identified. The image analysis is very costly in terms of time and compute resources. You are planning to use Azure Redis Cache so duplicate uploads do not need to be reprocessed. In case of an Azure data center outage, metadata loss must be kept to a minimum. You need to configure the Azure Redis cache instance. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
RDB persistence - When you use RDB persistence, Azure Cache for Redis persists a snapshot of your cache in a binary format. The snapshot is saved in an Azure Storage account. The configurable backup frequency determines how often to persist the snapshot. If a catastrophic event occurs that disables both the primary and replica cache, the cache is reconstructed using the most recent snapshot. Note: Azure Cache for Redis supports zone redundant configurations in the Premium and Enterprise tiers. A zone redundant cache can place its nodes across different Azure Availability Zones in the same region. It eliminates data center or AZ outage as a single point of failure and increases the overall availability of your cache. Incorrect: Not A: Zone redundancy doesn't support AOF persistence or work with geo-replication currently. Not C: No need for a second storage account.
