Microsoft Exam DP-420 Topic 2 Question 58 Discussion

Actual exam question for Microsoft's DP-420 exam

Question #: 58
Topic #: 2

You have a container in an Azure Cosmos DB Core (SQL) API account. The container stores telemetry data from IoT devices. The container uses telemetryId as the partition key and has a throughput of 1,000 request units per second (RU/s). Approximately 5,000 IoT devices submit data every five minutes by using the same telemetryId value.

You have an application that performs analytics on the data and frequently reads telemetry data for a single IoT device to perform trend analysis.

The following is a sample of a document in the container.

You need to reduce the amount of request units (RUs) consumed by the analytics application.

What should you do?

ADecrease the offerThroughput value for the container.

BIncrease the offerThroughput value for the container.

CMove the data to a new container that has a partition key of deviceId.

DMove the data to a new container that uses a partition key of date.

That's an interesting idea. It could help reduce the RUs consumed by the analytics application.

I disagree, I believe we should move the data to a new container that has a partition key of deviceId.

Choosing C seems like the best option here. Partitioning the data by deviceId will allow the analytics application to read data for a single IoT device more efficiently, reducing the RUs consumed.
