질문 # 104
You configure a backup for an Azure Cosmos DB for NoSQL account as shown in the following exhibit.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
NOTE: Each correct selection is worth one point.
정답：

Explanation
Box 1 = The current backup policy provides protection for: 2 Hours Azure Cosmos DB automatically takes backups of your data at regular intervals. The backup interval and the retention period can be configured from the Azure portal. You can also choose between two backup modes: periodic backup mode and continuous backup mode. Periodic backup mode is the default mode for all existing accounts and it takes a full backup of your database every 4 hours by default. Continuous backup mode is a new mode that allows you to restore to any point of time within either 7 or 30 days1.
For your scenario, based on the exhibit, you have configured a backup for an Azure Cosmos DB for NoSQL account using the periodic backup mode with a backup interval of 1 hour and a retention period of 2 hours.
This means that Azure Cosmos DB will take a full backup of your database every hour and keep only the latest two backups. Therefore, the current backup policy provides protection for 2 hours.
Box 2: In case of emergency, you must (answer choice) to restore the backup = create a support ticket Azure Cosmos DB automatically takes backups of your data at regular intervals. You can configure the backup interval and the retention period from the Azure portal. You can also choose between two backup modes:
periodic backup mode and continuous backup mode. Periodic backup mode is the default mode for all existing accounts and it takes a full backup of your database every 4 hours by default. Continuous backup mode is a new mode that allows you to restore to any point of time within either 7 or 30 days1.
For your scenario, based on the exhibit, you have configured a backup for an Azure Cosmos DB for NoSQL account using the periodic backup mode with a backup interval of 1 hour and a retention period of 2 hours.
This means that Azure Cosmos DB will take a full backup of your database every hour and keep only the latest two backups. In case of emergency, you must create a support ticket to restore the backup. This is the answer to your question.
To restore data from a periodic backup, you need to create a support request with Azure Cosmos DB team and provide the following information:
The name of your Azure Cosmos DB account
The name of the database or container that you want to restore
The date and time (in UTC) that you want to restore from
The name of the target Azure Cosmos DB account where you want to restore the data The name of the target resource group where you want to restore the data The Azure Cosmos DB team will then initiate the restore process and notify you when it is completed2.
질문 # 105
You are developing an application that will connect to an Azure Cosmos DB for NoSQL account. The account has a single readme region and one agonal read region. The regions are configured for automatic failover.
The account has the following connect strings. (Line numbers are included for reference only.)
For each of the following statements, select Yes if the statement is true. otherwise, select No.
NOTE: Each correct selection is worth one point.
정답：
설명：
Explanation:
If the primary write region fails, applications that write to the database must use a different connection string to continue to use the service. = NO You do not need to use a different connection string to continue to use the service if the primary write region fails. This is because Azure Cosmos DB supports automatic failover, which means that it will automatically switch the primary write region to another region in case of a regional o utage 2 . The application doe s not need to change the connection string or specify the failover priority 3 . The connection string contains a list of all the regions associated with your account, and Azure Cos mos DB will route the requests to the appropriate region based on the availability and latency 1 .
The primary Read-Only SQL Connection String and the Secondary Read-Only SQL Connection String will connect to different regions from an application running in the East US Azure region = Yes The primary read-only SQL connection string and the secondary read-only SQL connection string will connect to different regions from an application running in the East US Azure region. This is because the primary read-only SQL connection string contains the endpoint for the East US region, which is the same as the primary write region. The secondary read-only SQL connection string contains the endpoint for the West US region, which is the additional read region. Therefore, if an application running in the East US Azure region uses these connection strings, it will connect to different regions depending on which one it chooses.
Applications can choose from which region by setting the PreferredLocations property within their connection properties = Yes Applications can choose from which region by setting the PreferredLocations property within their connection properties. This property allows you to specify a list of regions that you prefer to read from based on their proximity to your application 2 . Azure Cosmos DB will route the requests to the appropriate region based on the availability and latency 1 . You can also set the ApplicationRegion property to the region where your application is deployed, and Azure Cosmos DB will automatically populate the PreferredLocations property based on the geo-proximity from that location 1 .
질문 # 106
You have an Azure Cosmos DB Core (SQL) API account named account1 that has the disableKeyBasedMetadataWriteAccess property enabled.
You are developing an app named App1 that will be used by a user named DevUser1 to create containers in account1. DevUser1 has a non-privileged user account in the Azure Active Directory (Azure AD) tenant.
You need to ensure that DevUser1 can use App1 to create containers in account1.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Explanation
Box 1: Resource tokens
Resource tokens provide access to the application resources within a database. Resource tokens:
Provide access to specific containers, partition keys, documents, attachments, stored procedures, triggers, and UDFs.
Box 2: Azure Resource Manager API
You can use Azure Resource Manager to help deploy and manage your Azure Cosmos DB accounts, databases, and containers.

질문 # 107
You have an Azure Cosmos DB for NoSQL database named DB1 that hosts the containers shown in the following table.
The user permissions are bound to a user and will NOT be queried independently of the user.
The product price is bound to a product and will NOT be queried independently of the product.
You are designing a new data model for DB1.
You need to optimize the data model to improve read performance and maintainability. The solution must meet the following requirements:
- Future enhancements of the user permissions must be supported.
- Future enhancements of the product price do NOT need to be supported.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
정답：B,C
설명：
To improve read performance and maintainability, you must transition from a normalized relational design to an optimized NoSQL design. NoSQL databases prioritize reading data in a single request rather than joining multiple containers.
Container Denormalization Strategy
[B]
Product Data (Container3 and Container4)
Action: Denormalize Container4 into Container3 by flattening the fields.
Product prices are never queried independently. Combining them allows a single read operation to fetch the complete product details.
Maintainability: Since future price enhancements are not required, you can directly flatten the price fields (e.g., price, currency) into the root of the product document. This keeps the schema simple and highly efficient.
[C]
User Data (Container1 and Container2)
Action: Denormalize Container2 into Container1 using reference (embedding as an array).
Users and permissions are always queried together. Embedding eliminates a second network call, drastically improving read performance.
Maintainability: Because future enhancements to permissions must be supported, embedding them as a strongly-typed JSON array or sub-object within the user document allows you to easily add new fields (e.g., expiration dates, scopes) later without breaking the schema.
