DP-420 Practice Test

Question 21

You are building an application that will store data in an Azure Cosmos DB Core (SQL) API account. The account uses the session default consistency level. The account is used by five other applications. The account has a single read-write region and 10 additional read region. Approximately 20 percent of the items stored in the account are updated hourly. Several users will access the new application from multiple devices. You need to ensure that the users see the same item values consistently when they browse from the different devices. The solution must NOT affect the other applications. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

1. Set the default consistency level to eventual
2. Associate a session token to the device
3. Use implicit session management when performing read requests
4. Provide a stored session token when performing read requests
5. Associate a session token to the user account

Question 22

You have a container that stores data about families. The following is a sample document. You run the following query against the container. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:

Question 23

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 Core (SQL) API 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 Azure Event Grid to send events to the function by using an Event Grid trigger in the function. Does this meet the goal?

1. Yes
2. No

Question 24

You have an application named App1 that reads the data in an Azure Cosmos DB Core (SQL) API account. App1 runs the same read queries every minute. The default consistency level for the account is set to eventual. You discover that every query consumes request units (RUs) instead of using the cache. You verify the IntegratedCacheiteItemHitRate metric and the IntegratedCacheQueryHitRate metric. Both metrics have values of 0. You verify that the dedicated gateway cluster is provisioned and used in the connection string. You need to ensure that App1 uses the Azure Cosmos DB integrated cache. What should you configure?

1. the indexing policy of the Azure Cosmos DB container
2. the consistency level of the requests from App1
3. the connectivity mode of the App1 CosmosClient
4. the default consistency level of the Azure Cosmos DB account

Question 25

You provision Azure resources by using the following Azure Resource Manager (ARM) template. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:
