Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB — Question 15

You provision an Azure Cosmos DB for NoSQL container. You set the throughput to Autoscale, and the maximum request units per second (RU/s) to 20,000.

For how many RU/s will you be charged when the actual RU/s usage is zero?

Answer options

• A. 0
• B. 200
• C. 2,000
• D. 4,000
• E. 10,000

Correct answer: C

Explanation

In Azure Cosmos DB with Autoscale enabled, even when the actual RU/s usage is zero, there is a minimum charge based on the provisioned throughput. For a maximum of 20,000 RU/s, the minimum charge is typically set at 2,000 RU/s, which is why option C is correct. The other options are incorrect as they do not reflect the minimum billing threshold for the Autoscale setting.
