DP-300 Plan and implement data platform resources Practice Question
You are designing a security strategy for Azure SQL Database. You need to ensure that database access is secured using Microsoft Entra ID (formerly Azure Active Directory) authentication. Which THREE actions should you take? (Choose THREE.)
⚠ Common exam trap
Test-takers frequently confuse enabling Entra ID authentication with disabling SQL Server authentication (Option B) or with enabling TDE (Option D), both of which are independent security controls not required for Entra ID-based access.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Microsoft Entra ID administrator for the Azure SQL logical server.
Creating a Microsoft Entra ID administrator for the Azure SQL logical server is required to enable Entra ID authentication at the server level. This administrator is a user or group from Entra ID that has permissions to manage all databases on the server, including creating contained database users mapped to Entra ID principals. Without this step, Entra ID authentication cannot be configured for the server or its databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a Microsoft Entra ID administrator for the Azure SQL logical server.
Why this is correct
An Entra ID admin is required to enable Entra ID authentication.
- ✗
Disable SQL Server authentication after migrating to Entra ID.
Why it's wrong here
Disabling SQL auth is optional and may break existing applications.
- ✓
Configure applications to use Microsoft Entra ID with MFA.
Why this is correct
Connecting with Entra ID authentication uses modern auth flows.
- ✗
Enable Transparent Data Encryption (TDE).
Why it's wrong here
TDE is for encryption at rest, not authentication.
- ✓
Create a contained database user mapped to a Microsoft Entra ID principal.
Why this is correct
