- A
Set the 'public_network_access' to 'Disabled'.
Why wrong: This disables public network access, not SQL authentication.
- B
Set the 'DisallowSqlAuthentication' property to 'True' on the logical server.
This property explicitly disallows SQL authentication, enforcing only Microsoft Entra authentication.
- C
Remove the SQL admin login after creating the database.
Why wrong: This does not prevent creation of other SQL logins.
- D
Create an Azure Policy to audit SQL authentication usage.
Why wrong: Auditing does not prevent creation; it only reports.

DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 configuring a new Azure SQL Database. The company policy requires that all connections use Microsoft Entra authentication and that no SQL authentication accounts exist. What should you do to prevent creation of SQL authenticated logins?
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 the 'DisallowSqlAuthentication' property to 'True' on the logical server.
Setting the 'DisallowSqlAuthentication' property to 'True' on the logical server enforces that only Microsoft Entra authentication can be used to connect to the Azure SQL Database. This property prevents the creation of any SQL authenticated logins, including the SQL admin account, and ensures compliance with the policy that no SQL authentication accounts exist.
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.
- ✗
Set the 'public_network_access' to 'Disabled'.
Why it's wrong here
This disables public network access, not SQL authentication.
- ✓
Set the 'DisallowSqlAuthentication' property to 'True' on the logical server.
Why this is correct
This property explicitly disallows SQL authentication, enforcing only Microsoft Entra authentication.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Remove the SQL admin login after creating the database.
Why it's wrong here
This does not prevent creation of other SQL logins.
- ✗
Create an Azure Policy to audit SQL authentication usage.
Why it's wrong here
Auditing does not prevent creation; it only reports.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-level controls (like disabling public network access) with authentication-level controls, or assume that auditing or post-creation removal of the SQL admin is sufficient to enforce a no-SQL-authentication policy.
Detailed technical explanation
How to think about this question
The 'DisallowSqlAuthentication' property is a server-level setting that, when enabled, blocks all SQL authentication attempts and prevents the creation of new SQL logins, including the server admin. This property is part of the Azure SQL logical server's authentication model and is enforced at the gateway layer, ensuring that even if a SQL login is somehow created, it cannot be used to authenticate. In a real-world scenario, this is critical for organizations that require a zero-trust security model and must eliminate legacy SQL authentication to reduce attack surface.
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.
