Question

You have an Azure Cosmos DB for NoSQL account that has multiple write regions. You need to receive an alert when requests that target the database exceed the available request units per second (RU/s). Which Azure Monitor signal should you use?

Options

ADocument Quota
BRegion Removed
CTotal Request Units
DDocument Count

Explanation

To receive an alert when Azure Cosmos DB database requests exceed the provisioned RU/s, you should monitor the 'Total Request Units' metric in Azure Monitor.

Common mistakes.

A. Document Quota refers to the maximum number of documents allowed, which is related to storage limits, not real-time request unit consumption.
B. Region Removed indicates a change in the geographical configuration of the Cosmos DB account, not related to current request unit consumption.
D. Document Count tracks the number of items stored in a container, which is a storage metric, not a throughput metric.
