SIMULATIONYou plan to perform performance testing of db1.You need prevent db1 from reverting to the last known good query plan.To complete this task, sign in to the virtual machine. You may need to use SQL Server Management Studio and the Azure portal.
Answer(s): A
Automatic tuning optionsThe automatic tuning options available in Azure SQL Database and Azure SQL Managed Instance are:* FORCE LAST GOOD PLAN (automatic plan correction)Identifies Azure SQL queries using an execution plan that is slower than the previous good plan, and forces queries to use the last known good plan instead of the regressed plan.* Etc.You can either manually apply tuning recommendations using the Azure portal, or you can let automatic tuning autonomously apply tuning recommendations for you.Azure defaults are set to FORCE_LAST_GOOD_PLAN enabled.We need to disable it.With transact-SQL:ALTER DATABASE SET options (Transact-SQL)Parameters include:<automatic_tuning_option> ::={AUTOMATIC_TUNING ( FORCE_LAST_GOOD_PLAN = { DEFAULT | ON | OFF } ) }Solution with T-SQLStored procedure executionYou can use the SQL Server Management Studio (SSMS) user interface or Transact-SQL in an SSMS query window to execute a stored procedure. Always use the latest version of SSMS.Use SQL Server Management StudioStep 1: In Object Explorer, connect to an instance of SQL Server or Azure SQL Database, expand that instance, and then expand Databases.Step 2: Expand the database that you want, expand Programmability, and then expand Stored Procedures.Step 3: Right-click the stored procedure that you want to run [here: ALTER DATABASE SET] and select Execute Stored Procedure.Step 4: Set the parameters: AUTOMATIC_TUNING ( FORCE_LAST_GOOD_PLAN = { OFF } )Step 5: Select OK to execute the stored procedure. If the stored procedure doesn't have any parameters, just select OK.

SIMULATIONYou have a legacy application written for Microsoft SQL Server 2012. The application will be the only application that accesses db1.You need to ensure that db1 is compatible with all the features and syntax of SQL Server 2012.To complete this task, sign in to the virtual machine. You may need to use SQL Server Management Studio and the Azure portal.
View or change the compatibility level of a databaseYou can view or change the compatibility level of a database in SQL Server, Azure SQL Database, or AzureSQL Managed Instance by using SQL Server Management Studio or Transact-SQL.Use SQL Server Management StudioTo view or change the compatibility level of a database using SQL Server Management Studio (SSMS)Step 1: Connect to the appropriate server or instance hosting your database [Here db1].Step 2: Select the server name in Object Explorer.Step 3: Expand Databases, and, depending on the database, either select a user database or expand System Databases and select a system database.Step 4: Right-click the database, and then select Properties.The Database Properties dialog box opens.Step 5: In the Select a page pane, select Options.The current compatibility level is displayed in the Compatibility level list box.Step 6: To change the compatibility level, select a different option from the list [Select SQL Server 2012]

[Here db1]Step 3: Right-click the Security folder, point to New, and select User....Step 4: In the Database User - New dialog box, on the General page, select one of the following user types from the User type list:SQL user with loginSQL user with password (when contained database is enabled) SQL user without loginUser mapped to a certificateUser mapped to an asymmetric key*-> Windows userStep 4a: Select Windows UserStep 5: When you select an option, the remaining options in the dialog may change. Some options only apply to specific types of database users. Some options can be left blank and will use a default value.User nameEnter a name for the new user. If you have chosen Windows user from the User type list, you can also select the ellipsis (...) to open the Select User or Group dialog box. [Specify User2-12345678]Step 6: Select OK.Stage 2: Assign permissionsAdditional OptionsThe Database User - New dialog box also offers options on four other pages: Owned Schemas, Membership, Securables, and Extended Properties.Step 7: Select SecurablesThe Securables page lists all possible securables and the permissions on those securables that can be granted to the login.Step 8: Select tablesStep 9: Grant Read Permission

HOTSPOT (Drag and Drop is not supported)You have an on-premises Microsoft SQL Server database named DB1.You have an Azure subscription.You need to migrate DB1 to an Azure SQL service that meets the following requirements:Protects the confidentiality of sensitive data from malware and high-privileged unauthorized database administratorsSupports pattern matching for server-side database operationsUses a hardware-based encryption technologyWhich Azure SQL service and attestation service should you include in the solution? To answer, select the appropriate options in the answer area.Note: Each correct selection is worth one point.Hot Area:
Box 1: The Azure SQL Database vCore purchasing modelAzure SQL Service vCore purchasing model - Azure SQL DatabaseHardware configurationCommon hardware configurations in the vCore model include standard-series (Gen5), Fsv2-series, and *DC- series*. Hyperscale also provides an option for premium-series and premium-series memory optimized hardware. Hardware configuration defines compute and memory limits and other characteristics that affect workload performance.Box 2: Microsoft Azure AttestationAttestation serviceAlways Encrypted with secure enclaves enables the database engine to process encrypted data within a protected memory area called a secure enclave. Secure enclaves enhance the confidential computing capabilities of Always Encrypted by supporting pattern matching, various comparison operators, and in-place encryption.Always Encrypted can use one of the two attestation services:* Microsoft Azure Attestation - a cloud-based attestation solution.* Host Guardian Service (HGS) that implements Windows Defender System Guard runtime attestation.The below table captures the supported attestation protocols for the valid SQL product and enclave type combinations:Note:Supported enclave technologiesAlways Encrypted supports the following enclave technologies (or enclave types):* Virtualization-based Security (VBS) enclaves (also known as Virtual Secure Mode, or VSM enclaves) - a software-based technology that relies on Windows hypervisor and doesn't require any special hardware.*-> Intel Software Guard Extensions (Intel SGX) enclaves - a *hardware-based* trusted execution environment technology.

You have an on-premises Microsoft SQL Server 2022 instance that hosts a 60-TB production database named DB1.You plan to migrate DB1 to Azure.You need to recommend a hosting solution for DB1.Which Azure SQL Database service tier should you use to host DB1?
Need Hyperscale for the 60-TB database.Compare resource limitsThe vCore-based service tiers are differentiated based on database availability, storage type, performance, and maximum storage size. These differences are described in the following table:
https://learn.microsoft.com/en-us/azure/azure-sql/database/service-tier-hyperscale
You have an Azure subscription.You plan to provision a single Azure SQL database.You need to ensure that the database supports the autoscaling of compute resources.Which service tier should you choose?
Answer(s): B
The General Purpose service tier in Azure SQL Database is designed to provide balanced and scalable compute and storage options. It supports the vCore-based purchasing model, which allows for autoscaling of compute resources. This model enables you to dynamically adjust the number of vCores allocated to your database, thereby allowing for autoscaling based on workload demands.
