This DP-300 practice question tests your understanding of implement a secure environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You need to configure authentication for Azure SQL Database. Which TWO options are supported?
Multi-factor authentication
Why wrong: Incorrect: MFA is part of Azure AD, not a standalone method.
Certificate-based authentication
Why wrong: Incorrect: Not directly supported.
Azure Active Directory authentication
Correct: Azure AD authentication is supported.
SQL authentication
Correct: SQL authentication is supported.
Windows authentication
Why wrong: Incorrect: Not supported for Azure SQL Database.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Active Directory authentication
Azure SQL Database supports Azure Active Directory (Azure AD) authentication, which allows you to centrally manage identities and access. This includes support for modern authentication protocols like OAuth 2.0 and integration with Azure AD, enabling features such as conditional access and managed identities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Incorrect: Not supported for Azure SQL Database.
Common exam traps
The trap here is that candidates often confuse Azure AD authentication with Windows authentication, thinking that because Azure AD is Microsoft's cloud identity service, it supports the same Kerberos-based Windows authentication as on-premises SQL Server, but Azure SQL Database does not support Windows authentication at all.
Detailed technical explanation
Azure SQL Database supports two authentication methods: SQL authentication (using a username and password stored in the database) and Azure AD authentication (using identities managed in Azure AD). Azure AD authentication can use various credential types, including user accounts, service principals, and managed identities, and it integrates with OAuth 2.0 tokens. A subtle behavior is that when using Azure AD authentication, the login must be an Azure AD user or group mapped to a contained database user, and the server-level principal (the SQL admin) cannot be an Azure AD account unless it is created as an Azure AD admin.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
