When provisioning an Azure Cosmos DB account, which feature provides redundancy within an Azure region?
- A . multi-master replication
- B . Availability Zones
- C . automatic failover
- D . the strong consistency level
Suggested Answer: B
Explanation:
With Availability Zone (AZ) support, Azure Cosmos DB will ensure replicas are placed across multiple zones within a given region to provide high availability and resiliency to zonal failures.
Note: Azure Cosmos DB provides high availability in two primary ways. First, Azure Cosmos DB replicates data across regions configured within a Cosmos account. Second, Azure Cosmos DB maintains 4 replicas of data within a region.
