Microsoft Azure Data Fundamentals DP-900 Practice Question

Azure Cosmos DB is a globally distributed, multi-model database service that automatically indexes all data by default, delivers single-digit-millisecond latency for reads and writes, and lets you select from several consistency levels (such as strong, bounded-staleness, session, or eventual). Azure SQL Database is a relational service that can store JSON but is optimized for structured, relational workloads and does not provide automatic indexing of every JSON property or the same global distribution and latency guarantees. Azure Blob Storage is object storage for unstructured data and does not provide automatic property indexing or transactional querying capabilities. A dedicated SQL pool in Azure Synapse Analytics is designed for large-scale analytical workloads, not for low-latency operational workloads with fine-grained document access.
