Microsoft Administering Relational Databases on Microsoft Azure Sample Questions:
You plan to create a table in an Azure Synapse Analytics dedicated SQL pool.
Data in the table will be retained for five years. Once a year, data that is older than five years will be deleted.
You need to ensure that the data is distributed evenly across partitions. The solutions must minimize the amount of time required to delete old data.
How should you complete the Transact-SQL statement? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all.
You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
Box 1: HASH
Box 2: OrderDateKey
In most cases, table partitions are created on a date column.
A way to eliminate rollbacks is to use Metadata Only operations like partition switching for data management.
For example, rather than execute a DELETE statement to delete all rows in a table where the order_date was in October of 2001, you could partition your data early. Then you can switch out the partition with data for an empty partition from another table.

https://docs.microsoft.com/en-us/azure/synapse-analytics/sql/best-practices-dedicated-sql-pool Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
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 the data is distributed evenly across partitions.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
You have an Azure subscription that contains an Azure SQL database.
The database fails to respond to queries in a timely manner.
You need to identify whether the issue relates to resource_semaphore waits.
How should you complete the Transact-SQL query? To answer, select the appropriate options in the answer area.

You have an Azure key vault named Vault1 and a SQL Server on Azure Virtual Machines instance named SQL1 SQL 1 hosts a database named DB1.
You need to configure Transparent Data Encryption (TDE) on D61 to use a key in Vault1 Which four actions should you perform in sequence ' To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Correct Answer:
Explanation:
Basic Concept: This question tests secure database administration, where the control must match the data state, access boundary, identity model, or compliance requirement.
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 configure Transparent Data Encryption (TDE) on D61 to use a key in Vault1 Which four actions should you perform in sequence ' To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Why the alternate choices are Wrong: The alternate sequence fails because key custody, application identity, and column encryption must be prepared in the correct order before the wizard can protect sensitive columns.
Task 2
You need to configure differential backups for the db1 Azure SQL database to be once a day instead of twice day. You may need to use SQL Server Management Studio and the Azure portal.
Correct Answer:
See the explanation part for the complete Solution.
Explanation:
Requirement: Configure differential backups for Azure SQL Database db1 to run once a day instead of twice a day.
Correct setting: Change Differential backup frequency from 12 Hours to 24 Hours.
Azure SQL Database supports differential backup frequency of either 12 hours or 24 hours. A 12-hour frequency means twice per day; a 24-hour frequency means once per day. Microsoft also notes that 24-hour differential backup frequency can increase restore time compared with 12-hour frequency.
Method 1 - Azure Portal Method
This is the best method for the simulation.
Step 1: Open the Azure SQL logical server
Sign in to the Azure portal.
Search for SQL servers.
Open the logical SQL server that hosts database db1.
Do not start from SQL Server Management Studio for this task. The differential backup frequency is an Azure SQL backup policy setting, not a normal T-SQL database setting.
Step 2: Open the Backups page
In the SQL server left menu, select Backups.
Select the Retention policies tab.
Microsoft's documented portal path is to go to the logical SQL server, select Backups, then select the Retention policies tab.
Step 3: Select database db1
In the list of databases, locate db1.
Select the checkbox next to db1.
Select Configure policies from the action bar.
Step 4: Change the differential backup frequency
In the policy configuration pane:
Find Differential backup frequency.
Change it from:
12 Hours
to:
24 Hours
Leave the PITR retention period unchanged unless the task specifically tells you to change it.
Select Apply or Save.
Microsoft's documented option is exactly 12 Hours or 24 hours under Differential backup frequency.
Method 2 - Azure CLI Method
Use this if the simulation provides Cloud Shell.
az sql db str-policy set \
--resource-group < resource-group-name > \
--server < server-name > \
--name db1 \
--retention-days < current-retention-days > \
--diffbackup-hours 24
Example:
az sql db str-policy set \
--resource-group RG1 \
--server sql60152867 \
--name db1 \
--retention-days 7 \
--diffbackup-hours 24
Microsoft documents az sql db str-policy set with --diffbackup-hours 24 for changing active database differential backup frequency. Valid values are 12 or 24 hours.
Be careful: do not guess the retention days blindly in a real environment. In the exam lab, use the existing retention value shown in the portal unless the task also asks you to change retention.
Method 3 - PowerShell Method
Use this if Azure PowerShell is available.
Set-AzSqlDatabaseBackupShortTermRetentionPolicy `
-ResourceGroupName " < resource-group-name > " `
-ServerName " < server-name > " `
-DatabaseName " db1 " `
-RetentionDays < current-retention-days > `
-DiffBackupIntervalInHours 24
Microsoft documents Set-AzSqlDatabaseBackupShortTermRetentionPolicy with -DiffBackupIntervalInHours
24 for setting Azure SQL Database differential backup frequency.
SSMS / T-SQL Clarification
For this task, SSMS is not the right tool to change the setting.
There is no normal ALTER DATABASE T-SQL command in Azure SQL Database to change automated differential backup frequency. Microsoft documents this change through:
Azure portal
Azure CLI
PowerShell
REST API
not SSMS/T-SQL.
You may use SSMS only to confirm the database exists and is accessible, but the backup frequency setting must be changed from Azure management tools.
