A. B. C. D. E.Correct Answer: B
Use Azure Cosmos DB when you need a NoSQL database of the supported API model, at planet scale, and with low latency performance.
Nowadays, Cosmos Databases support five-nines uptime (99.999 percent)
It is likely to support response times below 10 ms when it is provisioned correctly.
Option A is incorrect.
The requirements demand a NoSQL database.
Option B is correct.
Using Azure Cosmos DB is the right choice.
Option C is incorrect.
Azure DB server is not the right choice.
Option D is incorrect.
The requirements ask for a NoSQL database of a supported API model, with low latency performance and at planet scale which is Azure cosmos Database.
Option E is incorrect.
The question asks for a NoSQL Database.

If you require a NoSQL database with low latency performance and the ability to scale to a global level, then the appropriate option to use is Azure Cosmos DB (option B).
Azure Cosmos DB is a fully managed NoSQL database service offered by Microsoft Azure that is globally distributed and provides a multi-model API to enable you to store and access data with high availability and low latency performance. It supports multiple data models, including DocumentDB (JSON), MongoDB, Graph, Table, and Cassandra API.
Cosmos DB provides high availability and disaster recovery through global distribution and data replication across multiple regions. It also offers automatic and instant scalability with virtually unlimited throughput and storage capacity to handle the most demanding workloads.
Azure SQL Database (option A) is a fully managed relational database service that is suitable for applications that require relational data models, while Azure DB Server (option C) is a managed version of the open-source database, PostgreSQL.
Azure Database for PostgreSQL (option D) and Azure Database for MYSQL (option E) are managed PostgreSQL and MySQL database services that provide high availability, security, and scalability.
However, none of these options provide the same low latency and global scalability that Azure Cosmos DB offers. Therefore, Azure Cosmos DB is the best option to choose for a NoSQL database with low latency performance and global scalability.
