DP-300 Plan and implement data platform resources Practice Question
Your company is deploying a new application that uses an Azure SQL Database. The security policy requires that all connections use Microsoft Entra ID authentication and that no SQL authentication users are created. Which server-level setting should you enforce?
⚠ Common exam trap
Watch out — candidates often assume setting the Entra ID admin and disabling SQL authentication manually is sufficient, but the 'Azure AD-only authentication' property is a separate, explicit enforcement mechanism that must be enabled to fully block SQL authentication at the server level.
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
✓
Enable 'Azure AD-only authentication' on the Azure SQL logical server.
Enabling 'Azure AD-only authentication' on the Azure SQL logical server enforces that all connections must use Microsoft Entra ID authentication and blocks any SQL authentication attempts, even if SQL logins exist. This setting directly meets the security policy requirement that no SQL authentication users are created and all connections use Entra ID.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the database to use contained database authentication.
Why it's wrong here
Contained database authentication is not related to enforcing Entra ID only.
- ✗
Configure a server-level firewall rule to allow only Entra ID IPs.
Why it's wrong here
Firewall controls network access, not authentication type.
- ✓
Enable 'Azure AD-only authentication' on the Azure SQL logical server.
Why this is correct
This prevents SQL authentication connections.
- ✗
Set the Entra ID admin for the server and disable SQL authentication.
Why it's wrong here
There is no direct disable for SQL authentication; you must enable Azure AD-only authentication.
