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 two Azure SQL Database servers named Server1 and Server2. Each server contains an Azure SQL database named Database1. You need to restore Database1 from Server1 to Server2. The solution must replace the existing Database1 on Server2. Solution: You restore Database1 from Server1 to the Server2 by using the RESTORETransact-SQL command and the REPLACEoption. Does this meet the goal?
Correct Answer: A
Section: [none] Explanation: The REPLACE option overrides several important safety checks that restore normally performs. The overridden checks are as follows: * Restoring over an existing database with a backup taken of another database. With the REPLACE option, restore allows you to overwrite an existing database with whatever database is in the backup set, even if the specified database name differs from the database name recorded in the backup set. This can result in accidentally overwriting a database by a different database. Reference: https://docs.microsoft.com/en-us/sql/t-sql/statements/restore-statements-transact-sql
Question 57
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 two Azure SQL Database servers named Server1 and Server2. Each server contains an Azure SQL database named Database1. You need to restore Database1 from Server1 to Server2. The solution must replace the existing Database1 on Server2. Solution: From Microsoft SQL Server Management Studio (SSMS), you rename Database1 on Server2 as Database2. From the Azure portal, you create a new database on Server2 by restoring the backup of Database1 from Server1, and then you delete Database2. Does this meet the goal?
Correct Answer: B
Instead restore Database1 from Server1 to the Server2 by using the RESTORE Transact-SQL command and the REPLACE option. Note: REPLACE should be used rarely and only after careful consideration. Restore normally prevents accidentally overwriting a database with a different database. If the database specified in a RESTORE statement already exists on the current server and the specified database family GUID differs from the database family GUID recorded in the backup set, the database is not restored. This is an important safeguard. Reference: https://docs.microsoft.com/en-us/sql/t-sql/statements/restore-statements-transact-sql Perform Administration by Using T-SQL Testlet 1 This is a case study.

The main office hosts a sales department and the primary datacenter for the company. Physical Locations Existing Environment Litware has a manufacturing office and a research office is separate locations near Boston. Each office has its own datacenter and internet connection. The manufacturing and research datacenters connect to the primary datacenter by using a VPN. Network Environment The primary datacenter has an ExpressRoute connection that uses both Microsoft peering and private peering. The private peering connects to an Azure virtual network named HubVNet. Identity Environment Litware has a hybrid Azure Active Directory (Azure AD) deployment that uses a domain named litwareinc.com. All Azure subscriptions are associated to the litwareinc.com Azure AD tenant. Database Environment The sales department has the following database workload: * An on-premises named SERVER1 hosts an instance of Microsoft SQL Server 2012 and two 1-TB databases. * A logical server named SalesSrv01A contains a geo-replicated Azure SQL database named SalesSQLDb1. SalesSQLDb1 is in an elastic pool named SalesSQLDb1Pool. SalesSQLDb1 uses database firewall rules and contained database users. * An application named SalesSQLDb1App1 uses SalesSQLDb1. The manufacturing office contains two on-premises SQL Server 2016 servers named SERVER2 and SERVER3. The servers are nodes in the same Always On availability group. The availability group contains a database named ManufacturingSQLDb1 Database administrators have two Azure virtual machines in HubVnet named VM1 and VM2 that run Windows Server 2019 and are used to manage all the Azure databases. Licensing Agreement Litware is a Microsoft Volume Licensing customer that has License Mobility through Software Assurance. Current Problems SalesSQLDb1 experiences performance issues that are likely due to out-of-date statistics and frequent blocking queries. Requirements Planned Changes Litware plans to implement the following changes: * Implement 30 new databases in Azure, which will be used by time-sensitive manufacturing apps that have varying usage patterns. Each database will be approximately 20 GB. * Create a new Azure SQL database named ResearchDB1 on a logical server named ResearchSrv01. ResearchDB1 will contain Personally Identifiable Information (PII) data. * Develop an app named ResearchApp1 that will be used by the research department to populate and access ResearchDB1. * Migrate ManufacturingSQLDb1 to the Azure virtual machine platform. * Migrate the SERVER1 databases to the Azure SQL Database platform. Technical Requirements Litware identifies the following technical requirements: * Maintenance tasks must be automated. * The 30 new databases must scale automatically. * The use of an on-premises infrastructure must be minimized. * Azure Hybrid Use Benefits must be leveraged for Azure SQL Database deployments. * All SQL Server and Azure SQL Database metrics related to CPU and storage usage and limits must be analyzed by using Azure built-in functionality. Security and Compliance Requirements Litware identifies the following security and compliance requirements: * Store encryption keys in Azure Key Vault. * Retain backups of the PII data for two months. * Encrypt the PII data at rest, in transit, and in use. * Use the principle of least privilege whenever possible. * Authenticate database users by using Active Directory credentials. * Protect Azure SQL Database instances by using database-level firewall rules. * Ensure that all databases hosted in Azure are accessible from VM1 and VM2 without relying on public endpoints. Business Requirements Litware identifies the following business requirements: * Meet an SLA of 99.99% availability for all Azure deployments. * Minimize downtime during the migration of the SERVER1 databases. * Use the Azure Hybrid Use Benefits when migrating workloads to Azure. * Once all requirements are met, minimize costs whenever possible.
Question 58
You have an Azure SQL database. You identify a long running query. You need to identify which operation in the query is causing the performance issue. What should you use to display the query execution plan in Microsoft SQL Server Management Studio (SSMS)?
Correct Answer: C
Section: [none] Explanation: To include an execution plan for a query during execution 1. On the SQL Server Management Studio toolbar, click Database Engine Query. You can also open an existing query and display the estimated execution plan by clicking the Open File toolbar button and locating the existing query. 2. Enter the query for which you would like to display the actual execution plan. 3. On the Query menu, click Include Actual Execution Plan or click the Include Actual Execution Plan toolbar button. Note: Actual execution plans are generated after the Transact-SQL queries or batches execute. Because of this, an actual execution plan contains runtime information, such as actual resource usage metrics and runtime warnings (if any). The execution plan that is generated displays the actual query execution plan that the SQL Server Database Engine used to execute the queries. Reference: https://docs.microsoft.com/en-us/sql/relational-databases/performance/display-an-actual-execution-plan
Question 59
You have a new Azure SQL database. The database contains a column that stores confidential information. You need to track each time values from the column are returned in a query. The tracking information must be stored for 365 days from the date the query was executed. Which three actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Correct Answer: A,C,D
Section: [none] Explanation: C: Advanced Data Security (ADS) is a unified package for advanced SQL security capabilities. ADS is available for Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. It includes functionality for discovering and classifying sensitive data D: You can apply sensitivity-classification labels persistently to columns by using new metadata attributes that have been added to the SQL Server database engine. This metadata can then be used for advanced, sensitivity-based auditing and protection scenarios. A: An important aspect of the information-protection paradigm is the ability to monitor access to sensitive data. Azure SQL Auditing has been enhanced to include a new field in the audit log called data_sensitivity_information. This field logs the sensitivity classifications (labels) of the data that was returned by a query. Here's an example: Reference: https://docs.microsoft.com/en-us/azure/azure-sql/database/data-discovery-and-classification-overview
Question 60
You have an Azure SQL Database managed instance named SQLMI1. A Microsoft SQL Server Agent job runs on SQLMI1. You need to ensure that an automatic email notification is sent once the job completes. What should you include in the solution?
Correct Answer: C
To send a notification in response to an alert, you must first configure SQL Server Agent to send mail. Using SQL Server Management Studio; to configure SQL Server Agent to use Database Mail: * In Object Explorer, expand a SQL Server instance. * Right-click SQL Server Agent, and then click Properties. * Click Alert System. * Select Enable Mail Profile. * In the Mail system list, select Database Mail. * In the Mail profile list, select a mail profile for Database Mail. * Restart SQL Server Agent. Note: Prerequisites include: * Enable Database Mail. * Create a Database Mail account for the SQL Server Agent service account to use. * Create a Database Mail profile for the SQL Server Agent service account to use and add the user to the DatabaseMailUserRole in the msdb database. * Set the profile as the default profile for the msdb database.
