DP-300 Implement a secure environment Practice Question
You are designing a secure environment for Azure SQL Database. Which authentication method provides the strongest security and supports multi-factor authentication?
⚠ Common exam trap
Candidates often assume Windows authentication (Option D) is available in Azure SQL Database because of their on-premises experience, but Azure SQL Database does not support Windows authentication—only Azure AD authentication provides integrated identity management and MFA.

Correct answer & explanation
✓
Azure Active Directory authentication
Azure Active Directory (Azure AD) authentication is the recommended method for Azure SQL Database because it supports multi-factor authentication (MFA), conditional access policies, and identity-driven security. It eliminates the need for password management and leverages Azure AD's built-in security features, providing the strongest security posture for cloud-native environments.
