Scenario: Authenticate database users by using Active Directory credentials.

The configuration steps include the following procedures to configure and use Azure Active Directory authentication.

Create and populate Azure AD.

Optional: Associate or change the active directory that is currently associated with your Azure Subscription.

Create an Azure Active Directory administrator. (Step 1)

Configure your client computers.

Create contained database users in your database mapped to Azure AD identities. (Step 2)

Connect to your database by using Azure AD identities. (Step 3)

Scenario: Business Requirements

Litware identifies business requirements include: meet an SLA of 99.99% availability for all Azure deployments.

Box 1: Cloud witness

If you have a Failover Cluster deployment, where all nodes can reach the internet (by extension of Azure), it is recommended that you configure a Cloud Witness as your quorum witness resource.

Box 2: Azure Basic Load Balancer

Microsoft guarantees that a Load Balanced Endpoint using Azure Standard Load Balancer, serving two or more Healthy Virtual Machine Instances, will be available 99.99% of the time.

Note: There are two main options for setting up your listener: external (public) or internal. The external (public) listener uses an internet facing load balancer and is associated with a public Virtual IP (VIP) that is accessible over the internet. An internal listener uses an internal load balancer and only supports clients within the same Virtual Network.

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 B is Correct: For each customer, create an additional schema and grant the customer ddl_admin to the new schema. matches the expected DP-300 administration action. For each customer, create an additional schema and grant the customer ddl_admin to the new schema. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. 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 solution to ensure that the customers can create the database objects.

Why A is Wrong: For each customer, grant the customer ddl_admin to the existing schema. 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 C is Wrong: For each customer, create an additional schema and grant the customer db_writerto the new schema. 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.

Why D is Wrong: For each customer, grant the customer db_writerto the existing schema. 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.

Scenario: Authenticate database users by using Active Directory credentials.

(Create a new Azure SQL database named ResearchDB1 on a logical server named ResearchSrv01.)

Authenticate the user in SQL Database or SQL Data Warehouse based on an Azure Active Directory user:

CREATE USER [Fritz@contoso.com] FROM EXTERNAL PROVIDER;

The lifecycle management policy lets you:

Delete blobs, blob versions, and blob snapshots at the end of their lifecycles

Box 1: Hash

Scenario:

Ensure that queries joining and filtering sales transaction records based on product ID complete as quickly as possible.

A hash distributed table can deliver the highest query performance for joins and aggregations on large tables.

Box 2: Round-robin

Scenario:

You plan to create a promotional table that will contain a promotion ID. The promotion ID will be associated to a specific product. The product will be identified by a product ID. The table will be approximately 5 GB.

A round-robin table is the most straightforward table to create and delivers fast performance when used as a staging table for loads. These are some scenarios where you should choose Round robin distribution:

When you cannot identify a single key to distribute your data.

If your data doesn’t frequently join with data from other tables.

When there are no obvious keys to join.

Requirement: Configure active geo-replication for Azure SQL Database db1. The geo-replica must be created in East US or East US 2 on the logical Azure SQL server:

sql60152867-dr.database.windows.net

The important point: in Azure SQL, the logical server name used in portal/T-SQL is usually:

sql60152867-dr

not the full FQDN.

Microsoft states that active geo-replication is configured per database, and a geo-secondary is created for an existing Azure SQL Database. After creation and seeding, changes from the primary are replicated asynchronously to the secondary.

Method 1 — Azure Portal Method

This is the safest method for the simulation if the portal is available.

Step 1: Open the primary database

Sign in to the Azure portal.

Search for SQL databases.

Select the database named db1.

Confirm you are looking at the primary database, not an existing secondary.

Step 2: Open the Replicas blade

In the left menu of the db1 database page, scroll to Data management.

Select Replicas.

Select Create replica.

Microsoft’s portal workflow is: open the database, go to Data management > Replicas, and choose Create replica.

Step 3: Configure the geo-secondary replica

On the Create SQL Database replica page, configure the target like this:

Setting

Value

Database

db1

Replica type

Geo replica / Active geo-replication

Target server

sql60152867-dr

Region

East US or East US 2

Database name

db1

Compute + storage

Keep same or compatible with primary

Elastic pool

Only choose this if the lab specifically requires an elastic pool

Do not create a failover group unless the task asks for one. This task says active geo replication, so configure a database-level geo-replica, not a failover group. Microsoft explicitly separates active geo-replication from failover groups and notes that active geo-replication is configured per database.

Step 4: Review and create

Select Review + create.

Confirm the target server is:

sql60152867-dr

Confirm the region is either:

East US

or

East US 2

Select Create.

Azure will create the secondary database and begin the seeding process. Microsoft notes that the secondary database has the same name as the primary by default and begins replication after it is created and seeded.

Step 5: Verify replication

After deployment completes:

Go back to the primary database db1.

Open Replicas again.

Under Geo replicas, confirm that a replica exists on:

sql60152867-dr.database.windows.net

Confirm the replica status is healthy, online, or synchronizing.

You can also open the target SQL server sql60152867-dr and verify that a database named db1 now exists there.

Method 2 — SSMS / T-SQL Method

Use this method if the portal is awkward or the exam simulation expects T-SQL.

Step 1: Allow SSMS connectivity

Before connecting with SSMS:

In Azure portal, open the primary SQL server hosting db1.

Go to Networking or Firewalls and virtual networks.

Add your client IP address.

Repeat this on the secondary server:

sql60152867-dr.database.windows.net

This matters because SSMS must be able to connect to the Azure SQL logical server.

Step 2: Connect to the primary server in SSMS

Open SQL Server Management Studio.

Connect to the primary Azure SQL logical server that hosts db1.

Use SQL admin credentials or Microsoft Entra admin credentials.

In Connection Properties, connect to the database:

master

This is important. For Azure SQL Database geo-replication setup through T-SQL, run the command from the master database on the primary server.

Step 3: Run the active geo-replication command

Run this query:

ALTER DATABASE [db1]

ADD SECONDARY ON SERVER [sql60152867-dr]

WITH (ALLOW_CONNECTIONS = ALL);

Microsoft documents that ALTER DATABASE ... ADD SECONDARY ON SERVER creates a secondary database for an existing Azure SQL Database and starts data replication. The official example also uses WITH (ALLOW_CONNECTIONS = ALL) to create a readable geo-secondary.

Step 4: Verify the replication link

Still connected to the primary server, run:

SELECT *

FROM sys.geo_replication_links;

Or use:

SELECT *

FROM sys.dm_geo_replication_link_status;

Microsoft lists sys.geo_replication_links and sys.dm_geo_replication_link_status as views used to return information about existing replication links and replication status.

Optional PowerShell Method

Only use this if the lab gives you Cloud Shell or PowerShell access.

New-AzSqlDatabaseSecondary `

-ResourceGroupName " < PrimaryResourceGroupName > " `

-ServerName " < PrimaryServerName > " `

-DatabaseName " db1 " `

-PartnerResourceGroupName " < SecondaryResourceGroupName > " `

-PartnerServerName " sql60152867-dr " `

-PartnerDatabaseName " db1 "

Microsoft identifies New-AzSqlDatabaseSecondary as the PowerShell cmdlet that creates a secondary database for an existing Azure SQL Database and starts replication.

Final Answer / What You Must Achieve

The task is complete when:

Database db1 still exists on the primary server.

A secondary database named db1 exists on:

sql60152867-dr.database.windows.net

The target server is in East US or East US 2.

The replica appears under db1 > Replicas > Geo replicas.

Replication status is healthy, online, seeding, or synchronizing.

You did not configure a failover group unless separately requested.

To enable page compression on the PK_SalesOrderHeader_SalesOrderlD clustered index of the SalesLT.SalesOrderHeader table in db1, you can use the following Transact-SQL script:

-- Connect to the Azure SQL database named db1

USE db1;

GO

-- Enable page compression on the clustered index

ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader

REBUILD WITH (DATA_COMPRESSION = PAGE);

GO

This script will rebuild the clustered index with page compression, which can reduce the storage space and improve the query performance

The script solution consists of three parts:

The first part is USE db1; GO. This part connects to the Azure SQL database named db1, where the SalesLT.SalesOrderHeader table is located. The GO command separates the batches of Transact-SQL statements and sends them to the server.

The second part is ALTER INDEX PK_SalesOrderHeader_SalesOrderlD ON SalesLT.SalesOrderHeader REBUILD WITH (DATA_COMPRESSION = PAGE); GO. This part enables page compression on the clustered index named PK_SalesOrderHeader_SalesOrderlD, which is defined on the SalesLT.SalesOrderHeader table. The ALTER INDEX statement modifies the properties of an existing index. The REBUILD option rebuilds the index from scratch, which is required to change the compression setting. The DATA_COMPRESSION = PAGE option specifies that page compression is applied to the index, which means that both row and prefix compression are used. Page compression can reduce the storage space and improve the query performance by compressing the data at the page level. The GO command ends the batch of statements.

The third part is optional, but it can be useful to verify the compression status of the index. It is SELECT name, index_id, data_compression_desc FROM sys.indexes WHERE object_id = OBJECT_ID( ' SalesLT.SalesOrderHeader ' );. This part queries the sys.indexes catalog view, which contains information about the indexes in the database. The SELECT statement returns the name, index_id, and data_compression_desc columns for the indexes that belong to the SalesLT.SalesOrderHeader table. The OBJECT_ID function returns the object identification number for the table name. The data_compression_desc column shows the compression type of the index, which should be PAGE for the clustered index after the script is executed.

These are the steps of the script solution for enabling page compression on the clustered index of the SalesLT.SalesOrderHeader table in db1.

Connect to db1 in SQL Server Management Studio and run:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

Microsoft documents that Query Store maximum storage size is changed with:

ALTER DATABASE < database_name >

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = < size > );

For Azure SQL Database, the maximum allowed MAX_STORAGE_SIZE_MB value is 10,240 MB, so 4,000 MB is valid.

Method 1 — SSMS / T-SQL Method

This is the cleanest method for the simulation.

Step 1: Open SQL Server Management Studio

Open SQL Server Management Studio.

Connect to the Azure SQL logical server that hosts db1.

Use SQL authentication or Microsoft Entra authentication.

In Connection Properties, select:

db1

You can also connect to master, but for this task it is cleaner to open a query window in db1.

Step 2: Run the Query Store configuration command

Open a new query window and run:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

This changes the Query Store maximum allocated storage size to 4,000 MB.

Step 3: Verify the setting

Run this query in db1:

SELECT

actual_state_desc,

desired_state_desc,

current_storage_size_mb,

max_storage_size_mb

FROM sys.database_query_store_options;

Expected result:

max_storage_size_mb = 4000

Microsoft documents sys.database_query_store_options as the catalog view that returns Query Store configuration, including max_storage_size_mb.

Method 2 — SSMS Graphical Method

Use this if the simulation expects a GUI action.

Step 1: Connect to the server

Open SQL Server Management Studio.

Connect to the Azure SQL logical server.

Expand Databases.

Right-click db1.

Select Properties.

Step 2: Open Query Store settings

In the Database Properties window, select Query Store.

Find the setting:

Max Size (MB)

or:

Maximum Storage Size (MB)

Change the value to:

4000

Select OK.

Step 3: Verify

Run:

SELECT max_storage_size_mb

FROM sys.database_query_store_options;

Expected value:

4000

Azure Portal Clarification

The Azure portal is not the best tool for this specific Query Store configuration. Query Store size is a database engine setting, not a normal Azure resource setting like backup retention, locks, alerts, or private endpoints.

Use SSMS/T-SQL for this task.

Important Notes

Query Store must remain enabled

Do not disable Query Store. Azure SQL Database uses Query Store heavily, and Microsoft notes that Query Store is enabled by default for Azure SQL Database. The task only asks to increase the maximum storage size, not to change capture mode, cleanup policy, or operation mode.

4,000 MB is valid

Azure SQL Database allows Query Store MAX_STORAGE_SIZE_MB up to 10,240 MB, so this setting is within the allowed range.

Final Exam-Lab Action

Run this against db1:

ALTER DATABASE [db1]

SET QUERY_STORE (MAX_STORAGE_SIZE_MB = 4000);

Then verify with:

SELECT max_storage_size_mb

FROM sys.database_query_store_options;

The task is complete when the result shows:

4000

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: Configure connection strings that reference the read-write listener. is correct because it is the feature whose normal purpose matches the stated requirement. Configure connection strings that reference the read-write listener. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The scenario wording points to that specific behavior: You need to recommend which configuration to perform twice to enable access to the primary and secondary replicas of DB3.

Why A is Wrong: A service endpoint secures traffic to an Azure service over the Azure backbone but still targets the service public endpoint rather than giving it a private IP in the VNet. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.

Why B is Wrong: Database-level firewall rules restrict access to a specific Azure SQL database and are more granular than server-level firewall rules. 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.

Why C is Wrong: Create database-scoped credentials. 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.
