Question #: 3
Topic #: 5

You are developing a Microsoft Bot Framework app that consumes structured NoSQL data.
The app has the following data storage requirements:
Data must be stored in Azure.
Data persistence must be ensured.
You want to keep costs at a minimum.
Which of the following actions should you take?

A. Make use of Azure Blob storage
B. Make use of Azure Cosmos DB
C. Make use of Azure Databricks
D. Make use of Azure Table storage

Show Suggested Answer

Suggested Answer: D 🗳️
Table Storage is a NoSQL key-value store for rapid development using massive semi-structured datasets.
You can develop applications on Cosmos DB using popular NoSQL APIs.
Both services have a different scenario and pricing model.
While Azure Storage Tables is aimed at high capacity on a single region (optional secondary read only region but no failover), indexing by PK/RK and storage- optimized pricing; Azure Cosmos DB Tables aims for high throughput (single-digit millisecond latency), global distribution (multiple failover), SLA-backed predictive performance with automatic indexing of each attribute/property and a pricing model focused on throughput.

B. Make use of Azure Cosmos DB Azure Cosmos DB is a globally distributed, multi-model database service that supports NoSQL data storage. It provides high availability, scalability, and automatic data replication across multiple regions. Azure Cosmos DB ensures data persistence and offers various consistency models to choose from based on your application's requirements.
