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

You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account named account1.

Backups for account1 have the following configurations:

• Interval: 2 hours

• Retention period: 4 days

You need to estimate the charges associated with the retention of the backups. How many copies of the backups will incur additional charges?

You plan to create an Azure Cosmos DB container named account that will contain items in the following format.

You need to define a query that will return the ids of all accounts that have ever recorded a negative value for balance.

How should you complete the query? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

You have a database in an Azure Cosmos DB SQL API Core (SQL) account that is used for development.

The database is modified once per day in a batch process.

You need to ensure that you can restore the database if the last batch process fails. The solution must minimize costs.

How should you configure the backup settings? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

You are designing three apps named App1, App2, and App3. Each app will use a separate Azure Cosmos DB for NoSQL account. The apps have the following consistency requirements:

• App1: Reads must always return the most recent committed version of an item, where the commit occurred during the same session.

• App2: Reads must always return the most recent committed version of an item, even if the commit occurred during another session.

• App3: Write latency must be minimized and data staleness can be tolerated.

You need to recommend a default consistency level for each Azure Cosmos DB for NoSQL account. The solution must maximize concurrency.

What should you recommend for the account of each app? To answer, drag the appropriate consistency levels to the correct apps. Each consistency level may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

You have a container named contained in an Azure Cosmos DB for NoSQL account.

The following is a sample of a document in container1.

For each of the following statements, select Yes if the statement is true. Otherwise, select No.

NOTE: Each correct selection is worth one point.

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.

You have an Azure Cosmos DB for NoSQL container named Container1 that has a provisioned throughput of 1.000 request units per second (RU/s). Container1 is queried by using an app named App1.

Users of App1 report that several times a day, they receive the following error message: " HTTP error code 429. " You need to improve the reliability of App1 without affecting the performance of the app. What are two ways to improve the reliability? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

You plan to create an Azure Cosmos DB Core (SQL) API account that will use customer-managed keys stored in Azure Key Vault.

You need to configure an access policy in Key Vault to allow Azure Cosmos DB access to the keys.

Which three permissions should you enable in the access policy? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.
