The correct three actions are to create a Microsoft Entra ID administrator for the Azure SQL logical server, configure Azure SQL Database to support Entra ID authentication, and create a contained database user mapped to a Microsoft Entra ID principal. This sequence is essential because the server-level Entra ID administrator acts as the gateway for all Entra ID-based access; without this administrator, you cannot enable Entra ID authentication at the server level, and contained database users cannot be created. On the DP-300 exam, this scenario tests your understanding of the hierarchical dependency between server-level identity and database-level user mapping—a common trap is assuming you can create contained users without first setting the server administrator. Remember the order: server admin first, then database user. A useful mnemonic is “Admin first, user last” to avoid mixing up the configuration steps when configuring Microsoft Entra ID authentication for Azure SQL Database.
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 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.)
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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
Contained users allow Entra ID authentication at the database level.
Related concept

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
Entra ID authentication for Azure SQL Database uses OAuth 2.0 tokens for access, where the server validates tokens issued by Entra ID. Contained database users mapped to Entra ID principals (Option E) are stored in the user database and allow direct authentication without requiring a login in the master database, enabling granular per-database access control. MFA integration (Option C) adds a second factor via conditional access policies, which is critical for compliance scenarios like PCI DSS or HIPAA.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
