Identify Which Non-Relational Data Stores Support Read Replicas

You work as a database architect for MDFT Pro, a well-known training agency that provides Microsoft certification courses across multiple geographic regions. The company wants to improve read performance for their student management application by implementing read replicas that can serve queries from users in different locations. Mark, the performance optimization team lead, has asked you to identify which non-relational data storage services support read replica functionality.

Claire, the database administrator, needs to understand which services can provide readable copies of data in secondary regions to reduce latency for students and trainers accessing course information, enrollment records, and certification status from various global locations.

Which non-relational data stores support read replicas?

Choose the correct answer from the options below.

Explanations for each answer:

Azure Table storage only is incorrect. While Azure Table Storage does support read replicas through Read-access geo-redundant storage (RA-GRS), it's not the only service that provides this capability. Cosmos DB Table API also supports read replicas in multiple regions.
Cosmos DB Table API only is incorrect. Cosmos DB Table API does support read replicas and multi-region reads, but it's not the only service with this capability. Azure Table Storage also provides read replicas through geo-redundant storage options.
Cosmos DB Table API and Azure Table storage is correct. Both services support read replicas for improved global performance. Azure Table Storage provides read replicas through Read-access geo-redundant storage (RA-GRS), while Azure Cosmos DB Table API offers comprehensive global read replica capabilities with automatic failover and consistency options across multiple regions.
Neither service supports read replicas is incorrect. Both services actually support read replicas. Azure Table Storage provides this through RA-GRS (Read-access geo-redundant storage), and Cosmos DB Table API supports multi-region read replicas as a core feature.
