                                  Microsoft Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB Sample Questions:

                                  Question #1

                                  You have an Azure subscription. The subscription contains an Azure Cosmos DB for NoSQL account named account1 that hosts a container named Container1. Container1 has a provisioned throughput of 100 request units per second (RU/s) and uses a single physical partition.
                                  You are evaluating the available throughput for Container1.
                                  What is the maximum burst capacity that Container1 can accumulate?

                                  • A. 100,000 RU/s
                                  • B. 30,000 RU/s
                                  • C. 1,000 RU/s
                                  • D. 300 RU/s

                                  Correct Answer: D  🗳️

                                  Explanation: Only visible for TorrentVCE members. You can sign-up / login (it's free).

                                  Question #2

                                  Hotspot Question
                                  You have an Azure Cosmos DB account named account1 that has a default consistency level of session.
                                  You have an app named App1.
                                  You need to ensure that the read operations of App1 can request either bounded staleness or consistent prefix consistency.
                                  What should you modify for each consistency level? To answer, select the appropriate options in the answer area.

                                  Correct Answer:


                                  Explanation:
                                  Consistency can only be relaxed at the SDK instance or request level. To move from weaker to stronger consistency, update the default consistency for the Azure Cosmos DB account.

                                  Question #3

                                  You are designing an Azure Cosmos DB for NoSQL solution to store data from IoT devices.
                                  Writes from the devices will occur every second. Data will be retained indefinitely.
                                  The following is a sample of the data.

                                  You need to select a partition key that meets the following requirements for writes:
                                  - Minimizes the partition skew
                                  - Avoids capacity limits
                                  - Avoids hot partitions
                                  What should you do?

                                  • A. Create a new synthetic key that contains deviceId and deviceManufacturer.
                                  • B. Use deviceId as the partition key.
                                  • C. Create a new synthetic key that contains deviceId and timestamp.
                                  • D. Use deviceManufacturer as the partition key.

                                  Question #4

                                  You have an Azure Cosmos DB for NoSQL account.
                                  You need to perform detailed troubleshooting to view the deobfuscated query of all requests.
                                  What should you enable in the Azure portal?

                                  • A. ControlPlaneRequests
                                  • B. DataPlaneRequests
                                  • C. QueryRuntimeStatistics

                                  Question #5

                                  You are creating an Azure Cosmos DB for NoSQL account.
                                  You need to choose whether to configure capacity by using either provisioned throughput or serverless mode.
                                  Which two workload characteristics cause you to choose serverless mode? Each correct answer presents part of the solution.
                                  NOTE: Each correct selection is worth one point.

                                  • A. intermittent traffic
                                  • B. 25 TB of data in a single container
                                  • C. high average-to-peak traffic ratio
                                  • D. geo-distribution requirements
                                  • E. low average-to-peak traffic ratio
