You design data engineering solutions for a company that has locations around the world. You plan to
deploy a large set of data to Azure Cosmos DB.
The data must be accessible from all company locations. You need to recommend a strategy for deploying the data that minimizes latency for data read operations
and minimizes costs.
What should you recommend?
A . Use a single Azure Cosmos DB account. Enable multi-region writes.
B . Use a single Azure Cosmos DB account Configure data replication.
C . Use multiple Azure Cosmos DB accounts. For each account, configure the location to the closest Azure datacenter.
D . Use a single Azure Cosmos DB account. Enable geo-redundancy.
E . Use multiple Azure Cosmos DB accounts. Enable multi-region writes.
Answer: A
Explanation:
With Azure Cosmos DB, you can add or remove the regions associated with your account at any time.
Multi-region accounts configured with multiple-write regions will be highly available for both writes and reads. Regional failovers are instantaneous and don’t require any changes from the application.
