Question 961 of 919
DP-300 Implement a secure environment Practice Question
A company manages an Azure SQL Database that stores sensitive customer data. The security team mandates that all connections to the database use Azure Active Directory (Azure AD) authentication and that no SQL authentication logins exist. You are tasked with implementing this requirement. What should you do first?
⚠ Common exam trap
It's easy for candidates to confuse disabling network access or removing permissions with actually changing the authentication model, but the first required step is always to establish an Azure AD admin to enable Azure AD 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
✓
Set an Azure Active Directory admin for the Azure SQL Database server.
Before you can enforce Azure AD-only authentication, you must first designate an Azure AD admin for the Azure SQL Database server. This admin is the only identity that can manage Azure AD users and permissions in the database, and once set, you can then remove or disable SQL authentication logins. Without an Azure AD admin, there is no way to authenticate or manage Azure AD principals within the database, making the transition impossible.
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 server's 'Public network access' to 'Disabled'.
Why it's wrong here
This only restricts network access, not authentication method.
- ✗
Remove the server admin login from the master database.
Why it's wrong here
Cannot remove the server admin without first having an Azure AD admin.
- ✓
Set an Azure Active Directory admin for the Azure SQL Database server.
Why this is correct
An Azure AD admin must be set before disabling SQL authentication.
- ✗
Deny the CONNECT permission to all SQL authentication logins.
Why it's wrong here
This can be done after setting Azure AD admin but is not the first step.
