* Automatic tuning
* Change tracking
* PolyBase

NEW QUESTION # 274
You need to recommend an availability strategy for an Azure SQL database. The strategy must meet the following requirements:
* Support failovers that do not require client applications to change their connection strings.
* Replicate the database to a secondary Azure region.
* Support failover to the secondary region.
What should you include in the recommendation?
Answer: A
Explanation:
Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a server in the same or different data center (region).
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/active-geo-replication-overview
NEW QUESTION # 275
You have an on-premises server named Server1 that has Microsoft SQL Server installed. Server1 contains a database named DB1. You have an Azure subscription that contains a user named User1. You need to ensure that User1 can perform the following actions:
* Register a resource provider to support migrating DB1 to Azure.
* Create an Azure Database Migration Service instance
* Migrate DB1 to Azure SQL Database.
The solution must follow the principle of least privilege.
Which role should you assign to User1 for the subscription, and which resource provider should User1 register? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
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 ensure that User1 can perform the following actions: * Register a resource provider to support migrating DB1 to Azure.
Why the alternate choices are Wrong: The alternate selections would either use a migration tier that does not match the downtime requirement, choose a network resource that does not support the migration path, or add an unnecessary deployment component.
NEW QUESTION # 276
Task 5
You need to configure a disaster recovery solution for db1. When a failover occurs, the connection strings to the database must remain the same. The secondary server must be in the West US 3 Azure region.
Answer:
Explanation:
See the explanation part for the complete Solution.
Explanation:
To configure a disaster recovery solution for db1, you can use the failover groups feature of Azure SQL Database. Failover groups allow you to manage the replication and failover of a group of databases across different regions with the same connection strings1. You can also use active geo-replication as an alternative, but you will need to update the connection strings manually after a failover2.
Here are the steps to create a failover group for db1 with the secondary server in the West US 3 region:
Using the Azure portal:
Go to the Azure portal and select your Azure SQL Database server that hosts db1.
Select Failover groups in the left menu and click on Add group.
Enter a name for the failover group and select West US 3 as the secondary region.
Click on Create a new server and enter the details for the secondary server, such as server name, admin login, password, and subscription.
Click on Select existing database(s) and choose db1 from the list of databases on the primary server.
Click on Configure failover policy and select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.
Click on Create to create the failover group and start the replication of db1 to the secondary server.
Using PowerShell commands:
Install the Azure PowerShell module and log in with your Azure account.
Run the following command to create a new server in the West US 3 region: New-AzSqlServer - ResourceGroupName < your-resource-group-name > -ServerName < your-secondary-server-name > - Location " West US 3 " -SqlAdministratorCredentials $(New-Object -TypeName System.Management.
Automation.PSCredential -ArgumentList " < your-admin-login > " , $(ConvertTo-SecureString -String " < your-password > " -AsPlainText -Force)) Run the following command to create a new failover group with db1: New-AzSqlDatabaseFailoverGroup - ResourceGroupName < your-resource-group-name > -ServerName < your-primary-server-name > - PartnerResourceGroupName < your-resource-group-name > -PartnerServerName < your-secondary-server- name > -FailoverGroupName < your-failover-group-name > -Database db1 -FailoverPolicy Manual - GracePeriodWithDataLossHours 1 -ReadWriteFailoverEndpoint " Enabled " You can modify the parameters of the command according to your preferences, such as the failover policy, grace period, and read-write failover endpoint mode.
These are the steps to create a failover group for db1 with the secondary server in the West US 3 region.
