You need to capture detailed information about data-plane operations, such as the partition key and request charge, for an Azure Cosmos DB account. What should you enable?

Azure Application Insights for the Azure Cosmos DB account.

Azure Monitor resource logs for the Azure Cosmos DB account.

Azure Activity Log for the Azure Cosmos DB account.

Azure Defender for Cloud for the Azure Cosmos DB account.

A media company uses Cosmos DB for a user-profile service. The operations team wants to be notified immediately when the rate of 429 responses exceeds 1% of total requests for 10 minutes. Which alert rule should they configure?

Metric alert on 'Total Request Units' with a threshold of 90%

Log alert querying 'AzureDiagnostics' for 'StatusCode' = 429 and calculating the percentage

Metric alert on 'Total Requests' with a threshold of 1000

Metric alert on 'Server Side Latency' with a threshold of 100 ms

A company has a Cosmos DB container with a partition key that causes uneven request distribution. They are considering changing the partition key. Before doing so, they want to quantify the impact of the current skew on throughput. Which two metrics should they compare?

DataPlaneRequests logs and QueryRuntimeStatistics logs

Server Side Latency and Total Requests

Replication Lag and Normalized RU Consumption

Normalized RU Consumption by PartitionKeyRangeID and Total Requests by PartitionKeyRangeID

A developer is troubleshooting a failed Azure Cosmos DB operation. The response status code is 429. What does this status code indicate?

The request was rejected because the client is not authorized to access the resource.

The request failed because the requested resource was not found.

The request was throttled because the provisioned throughput was exceeded.
