Prerequisites
The DP-300 certification exam has no official prerequisite. However, the candidates for the test should have the skills and knowledge in the areas of management, security, optimization, security, and monitoring up-to-date solutions for a relational database. Although any professional can take this exam, it is generally intended for database administrators. These experts work with the Azure data engineers in managing the operational components of data platform solutions. It is recommended that the applicants understand the concepts that are covered in this test before attempting it.
Microsoft Administering Relational Databases on Microsoft Azure Sample Questions:
You have an Azure SQL database named SOL1.

Task 4
You need to enable change data capture (CDC) for db1.
Correct Answer:
See the explanation part for the complete Solution.
Explanation:
To enable change data capture (CDC) for db1, you need to run the stored procedure sys.sp_cdc_enable_db in the database context. CDC is a feature that records activity on a database when tables and rows have been modified1. CDC can be used for various scenarios, such as data synchronization, auditing, or ETL processes2.
Here are the steps to enable CDC for db1:
Connect to db1 using SQL Server Management Studio, Azure Data Studio, or any other tool that supports Transact-SQL statements.
Open a new query window and run the following command: EXEC sys.sp_cdc_enable_db; GO This command will enable CDC for the database and create the cdc schema, cdc user, metadata tables, and other system objects for the database3.
To verify that CDC is enabled for db1, you can query the is_cdc_enabled column in the sys.databases catalog view. The value should be 1 for db1.
These are the steps to enable CDC for db1
You are planning disaster recovery for the failover group of an Azure SQL Database managed instance.
Your company's SLA requires that the database in the failover group become available as quickly as possible if a major outage occurs.
You set the Read/Write failover policy to Automatic.
What are two results of the configuration? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. In the event of an outage, the minimum delay for the databases to fail over in the primary instance will be one hour.
- B. In the event of an outage, you can set a different grace period to fail over each database.
- C. In the event of a datacenter or Azure regional outage, the databases will fail over automatically.
- D. In the event of an outage, you can selectively fail over individual databases.
- E. In the event of an outage, the databases in the primary instance will fail over immediately.
Correct Answer: A,C 🗳️
Explanation: Only visible for PassSureExam members. You can sign-up / login (it's free).
You have two Azure virtual machines named VM1 and VM2 that run Windows Server 2019. VM1 and VM2 each host a default Microsoft SQL Server 2019 instance. VM1 contains a database named DB1 that is backed up to a file named D:\DB1.bak.
You plan to deploy an Always On availability group that will have the following configurations:
VM1 will host the primary replica of DB1.
VM2 will host a secondary replica of DB1.
You need to prepare the secondary database on VM2 for the availability group.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
Correct Answer:
Explanation:
Reference:
https://docs.microsoft.com/en-us/sql/database-engine/availability-groups/windows/manually-prepare-a-secondary-database-for-an-availability-group-sql-server?view=sql-server-ver15 Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
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 prepare the secondary database on VM2 for the availability group.
Why the alternate choices are Wrong: The alternate choices do not satisfy the stated availability design because quorum and listener resources must match Azure failover-cluster behavior and the required SLA.
