Question 8
UnclassifiedWhich metric set is most useful for Cosmos DB operations?
Correct answer: D
Explanation
Cosmos DB operations are best monitored with metrics that show capacity use and service health: RU consumption, throttling, latency, availability, storage, and query behavior. These measures reveal whether requests are being served efficiently, limited by throughput, or affected by performance and uptime issues.
Why each option is right or wrong
A. The number of icons in the portal.
B. Team vacation schedule only.
C. Browser bookmark count.
D. RU consumption, throttling, latency, availability, storage, and query behavior.
Azure Cosmos DB’s monitoring guidance centers on the platform metrics exposed in Azure Monitor for request units, throttled requests, latency, availability, storage, and query execution patterns, because these directly reflect throughput pressure and service health. In practice, RU/s consumption and 429 throttling indicate whether the provisioned throughput is being exceeded, while latency, availability, storage, and query metrics show performance, uptime, capacity growth, and inefficient query behavior that can drive RU usage.
