   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.

   • ASet the default consistency level to eventual
   • BAssociate a session token to the device
   • CUse implicit session management when performing read requests
   • DProvide a stored session token when performing read requests
   • EAssociate a session token to the user account

   You plan to create an Azure Cosmos DB for NoSQL database named db1 that will contain two containers. One of the containers will contain blog posts, and the other will contain users. Each item in the blog post container will include: • A single blog post • The top 10 comments associated to the blog post • The names of the users who created the blog post and the associated comments You need to automatically update the usernames in the blog post container whenever a username in the user container changes. What should you implement for the user container?

   • Aa stored procedure
   • Ba change feed processor
   • Ca post-trigger
   • Da user-defined function (UDF)

   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?

   • AYes
   • BNo

   You have an Azure Cosmos DB for NoSQL account. The account hosts a container that has the change feed enabled. You are building an app by using the Azure Cosmos DB SDK. The app will read items from the change feed by using a pull model. You need to ensure that multiple threads can read the change feed in parallel. What should you include?

   • Athe ChangeFeedStartFrom value
   • Bthe pagesize value
   • Cthe FeedRange value
   • Da stream-based iterator

5. Question 75 · 106 in bank

   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?

   • Athe indexing policy of the Azure Cosmos DB container
   • Bthe consistency level of the requests from App1
   • Cthe connectivity mode of the App1 CosmosClient
   • Dthe default consistency level of the Azure Cosmos DB account

You need to make the contents of container1 available as reference data for an Azure Stream Analytics job. Solution: You create an Azure Synapse pipeline that uses Azure Cosmos DB for NoSQL change feed as a trigger and an Azure event hub as the output. Does this meet the goal?

   You have an Azure Cosmos DB for NoSQL container. All queries to the container use the Bounded Staleness consistency level. You discover that when many queries are executed against the container, an HTTP 429 error is returned. What are two ways to reduce the number of HTTP 429 errors? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

   • AUse a query request option to change the consistency level to Strong.
   • BAdd a post-trigger to the container.
   • CAdd a pre-trigger to the container.
   • DAdd query retry logic to the client application.
   • EIncrease the maximum throughput.
