NEW QUESTION # 447
You need to recommend a disaster recovery solution for an on-premises Microsoft SQL Server database. The solution must meet the following requirements:
* Support real-time data replication to a different geographic region.
* Use Azure as a disaster recovery target.
* Minimize costs and administrative effort.
What should you include in the recommendation?
Answer: A
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 D is Correct: transactional replication to an Azure SQL Managed Instance matches the expected DP-300 administration action. Transactional replication distributes committed changes to subscribers, but it is not the default full-database migration method for Azure SQL Managed Instance when the requirement is minimal effort. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You need to recommend a disaster recovery solution for an on-premises Microsoft SQL Server database.
Why A is Wrong: database mirroring on an instance of SQL Server on Azure Virtual Machines is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
Why B is Wrong: availability groups for SQL Server on Azure Virtual Machines is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
Why C is Wrong: an Azure SQL Managed Instance link is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
NEW QUESTION # 448
You have an Azure subscription that contains an Azure SQL database. The database contains a table named tablet.
You execute the following Transact-SQL statements.
You need to reduce the time it takes to perform analytic queries on the database.
Which configuration should you enable?
Answer: D
NEW QUESTION # 449
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 strings 1 . You can also use active geo-replication as an alternative, but you will need to update the connection strings manually after a failover 2 .
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 Azur e 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 -Typ eName 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 -FailoverPo licy 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.
