The correct answer is C. Provisioned Throughput. To alert when requests to an Azure Cosmos DB database exceed its available request units per second (RU/s), you should use the Azure Monitor signal that tracks provisioned throughput metrics.

Why each option

To alert when requests to an Azure Cosmos DB database exceed its available request units per second (RU/s), you should use the Azure Monitor signal that tracks provisioned throughput metrics.

ARegion Removed

`Region Removed` indicates a change in the account's region configuration, not its operational throughput.

BMetadata Requests

`Metadata Requests` tracks requests for metadata operations, which are distinct from data read/write operations that consume provisioned throughput.

CProvisioned ThroughputCorrect

The `Provisioned Throughput` metric directly measures the Request Units per second (RU/s) allocated to a database or container. Alerts can be configured on this signal to trigger when the consumed RU/s approach or exceed the provisioned amount, indicating potential throttling.

DData Usage

`Data Usage` typically refers to storage consumption, not the rate of request units consumed.
