DP-420 Exam Dumps : Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB

You have an Azure subscription.

You plan to implement an Azure Cosmos DB for NoSQL single-region write account named account1 that will replicate across two Azure regions.

You need to set the default consistency level for account1. The solution must meet the following requirements:

• Writes must be performed to a local majority in a single region.

• Reads must be performed from a local minority in a single region.

Which consistency level should you select?

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.

You need to make the contents of container1 available as reference data for an Azure Stream Analytics job.

Solution: You create an Azure function that uses Azure Cosmos DB Core (SQL) API change feed as a trigger and Azure event hub as the output.

Does this meet the goal?

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?
