Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Cosmos DB
Azure Cosmos DB (option D) offers multi-region replication, flexible schema, and low latency. Azure Table Storage (option E) is a NoSQL key-value store with global replication (read-access geo-redundant storage) and low latency. Option A (Azure Files) is file storage, not a non-relational data store meeting these needs. Option B (Azure SQL Database) is relational. Option C (Azure Cache for Redis) is an in-memory cache, not a primary data store.
