NEW QUESTION # 168
You have SQL Server on an Azure virtual machine that contains a database named DB1.
You have an application that queries DB1 to generate a sales report.
You need to see the parameter values from the last time the query was executed.
Which two actions should you perform? Each correct answer presents part of the solution.

Section: [none]
Explanation:
Last_Query_Plan_Stats allows you to enable or disable collection of the last query plan statistics (equivalent to
an actual execution plan) in sys.dm_exec_query_plan_stats.
Lightweight profiling can be disabled at the database level using the LIGHTWEIGHT_QUERY_PROFILING
database scoped configuration: ALTER DATABASE SCOPED CONFIGURATION SET
LIGHTWEIGHT_QUERY_PROFILING = OFF;.
Incorrect Answers:
E: Parameter sensitivity, also known as "parameter sniffing", refers to a process whereby SQL Server "sniffs"
the current parameter values during compilation or recompilation, and passes it along to the Query Optimizer
so that they can be used to generate potentially more efficient query execution plans.
Parameter values are sniffed during compilation or recompilation for the following types of batches:
* Stored procedures
* Queries submitted via sp_executesql
* Prepared queries

NEW QUESTION # 171
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.
