You are deploying an application that will use an Azure Cosmos DB database. Users of the application will be located in Seattle, London, and Singapore. The application will be used to read and write to the database.
The users in each location will access the application only between 09:00 and 17:00 local time. Business hours do not overlap between the locations.
You need to recommend a solution to minimize write latency during business hours.
What should you recommend
A . Deploy three separate Cosmos DB accounts. Deploy the application to three Azure regions. Create a job that automates a backup and restore of the accounts.
B . Deploy three separate Cosmos DB accounts Deploy the application to three Azure regions. Create a job that reconfigures the connections for each application.
C . Deploy a Cosmos DB account that replicates to three Azure regions. Deploy the application to the three regions, Configure the Cosmos DB account for automatic failover.
D . Deploy a Cosmos DB account that replicates to three Azure regions. Deploy the application to the three regions. Create a job that automates a manual failover of the write region.
Answer: D
