Explanation:
Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to modify the Query Store configuration to ensure that performance monitoring data is available as soon as possible.
Why the alternate choices are Wrong: The alternate destinations or collection scopes miss part of the telemetry requirement: they either omit the server/pool/database layer or send data somewhere that does not support the requested analysis path.

정답:
Explanation:
Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to provision an Azure Storage account to host a cloud witness for the deployment.
Why the alternate choices are Wrong: The alternate choices do not satisfy the stated availability design because quorum and listener resources must match Azure failover-cluster behavior and the required SLA.

Basic Concept: This question tests identity and authentication for Azure SQL and SQL Server workloads, including when to use contained users, directory identities, certificate validation, or authentication profiles.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to create a new database user for app1.
Why the alternate choices are Wrong: The alternate actions fail because Entra authentication must be established at the server/administrator level first, then mapped to contained database users, and finally used by the client connection.

You have an Azure SQL database that contains a table named Customer. Customer has the columns shown in the following table.
You plan to implement a dynamic data mask for the Customer_Phone column. The mask must meet the following requirements:
The first six numerals of each customer's phone number must be masked.
The last four digits of each customer's phone number must be visible.
Hyphens must be preserved and displayed.

Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
Task 1
In an Azure SQL database named db1, you need to enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.SalesOrderHeader table.
In an Azure SQL database named db1, you need to enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.SalesOrderHeader table.
정답:
See the explanation part for the complete Solution.
Explanation:
To enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.
SalesOrderHeader table in db1, you can use the following Transact-SQL script:
-- Connect to the Azure SQL database named db1
USE db1;
GO
-- Enable page compression on the clustered index
ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader REBUILD WITH (DATA_COMPRESSION = PAGE); GO This script will rebuild the clustered index with page compression, which can reduce the storage space and improve the query performance The script solution consists of three parts:
The first part is USE db1; GO. This part connects to the Azure SQL database named db1, where the SalesLT.
SalesOrderHeader table is located. The GO command separates the batches of Transact-SQL statements and sends them to the server.
The second part is ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader REBUILD WITH (DATA_COMPRESSION = PAGE); GO. This part enables page compression on the clustered index named PK_SalesOrderHeader_SalesOrderlD, which is defined on the SalesLT.
SalesOrderHeader table. The ALTER INDEX statement modifies the properties of an existing index.
The REBUILD option rebuilds the index from scratch, which is required to change the compression setting.
The DATA_COMPRESSION = PAGE option specifies that page compression is applied to the index, which means that both row and prefix compression are used. Page compression can reduce the storage space and improve the query performance by compressing the data at the page level. The GO command ends the batch of statements.
The third part is optional, but it can be useful to verify the compression status of the index. It is SELECT name, index_id, data_compression_desc FROM sys.indexes WHERE object_id = OBJECT_ID( ' SalesLT.
SalesOrderHeader ' );. This part queries the sys.indexes catalog view, which contains information about the indexes in the database. The SELECT statement returns the name, index_id, and data_compression_desc columns for the indexes that belong to the SalesLT.SalesOrderHeader table. The OBJECT_ID function returns the object identification number for the table name. The data_compression_desc column shows the compression type of the index, which should be PAGE for the clustered index after the script is executed.
These are the steps of the script solution for enabling page compression on the clustered index of the SalesLT.
SalesOrderHeader table in db1.

You plan to create an automation runbook that will create database users in db1 from Azure AD identities.
You need to configure sq1370O6895 to support the creation of new database users.
You plan to create an automation runbook that will create database users in db1 from Azure AD identities.
You need to configure sq1370O6895 to support the creation of new database users.
정답:
See the explanation part for the complete Solution.
Explanation:
To configure sq1370O6895 to support the creation of new database users from Azure AD identities, you need to do the following steps:
Set up a Microsoft Entra tenant and associate it with your Azure subscription. You can use the Microsoft Entra portal or the Azure portal to create and manage your Microsoft Entra users and groups12.
Configure a Microsoft Entra admin for sq1370O6895. You can use the Azure portal or the Azure CLI to set a Microsoft Entra user as the admin for the server34. The Microsoft Entra admin can create other database users from Microsoft Entra identities5.
Connect to db1 using the Microsoft Entra admin account and run the following Transact-SQL statement to create a new database user from a Microsoft Entra identity: CREATE USER [Microsoft Entra user name] FROM EXTERNAL PROVIDER;6 You can replace the Microsoft Entra user name with the name of the user or group that you want to create in the database.
Grant the appropriate permissions to the new database user by adding them to a database role or granting them specific privileges. For example, you can run the following Transact-SQL statement to add the new user to the db_datareader role: ALTER ROLE db_datareader ADD MEMBER [Microsoft Entra user name]; These are the steps to configure sq1370O6895 to support the creation of new database users from Azure AD identities.
