  • Question 1
    • An Azure Cosmos DB Core (SQL) API account has a container that stores telemetry data from IoT devices. The container utilizes telemetryId as the partition key and has a throughput of 1000 RU/s (request units per second). Data is submitted by approx 5000 IoT devices by using the same telemetryId value every 5 minutes.

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

      The below figure demonstrates the sample of a document in the container:

      What would you do for reducing the number of RUs consumed by the analytics app?


      Answer: D
  • Question 2

    • You have a container named container1 in an Azure Cosmos DB for NoSQL account named account1 that is set to the session default consistency level. The average size of an item in container1 is 20 KB. You have an application named App1 that uses the Azure Cosmos DB SDK and performs a point read on the same set of items in container1 every minute. You need to minimize the consumption of the request units (RUs) associated to the reads by App1. What should you do? 


      Answer: C
  • Question 3
    • 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 an Azure Cosmos DB for NoSQL account named account1 that uses autoscale throughput.

      You need to run an Azure function when the normalized request units per second for a container in account1

      exceeds a specific value.

      Solution: You configure an Azure Monitor alert to trigger the function.

      Does this meet the goal?


      Answer: A
  • Question 4
    • In a shared throughput database, the containers share the throughput (Request Units per Second) allocated to that database. In a manually provisioned throughput, it is possible to have up to ………… containers with a minimum ……………. Request Units per second on the database.

      Answer: B
  • Question 5
    • You need to implement a solution to meet the product catalog requirements. What should you do to implement the conflict resolution policy.
