- A
Use a server-level firewall rule to restrict access to the tenant's IP.
Why wrong: Firewall does not restrict permissions.
- B
Create a contained database user with db_owner role in each tenant's database and use Microsoft Entra authentication.
Contained users are scoped to the database.
- C
Create a server-level login and assign it as db_owner on all databases.
Why wrong: Server-level login can access all databases if granted.
- D
Create a database-level firewall rule for each tenant database.
Why wrong: Firewall rules control network access, not permissions.

DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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 configuring Azure SQL Database for a multi-tenant application. Each tenant's data is stored in a separate database. You need to ensure that a tenant admin can only manage their own database and not other databases on the same logical server. What is the best approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
✓
Create a contained database user with db_owner role in each tenant's database and use Microsoft Entra authentication.
Option B is correct because creating a contained database user with the db_owner role in each tenant's database, using Microsoft Entra authentication, ensures that the tenant admin can only manage their own database. Contained database users are scoped to the individual database, not the logical server, so they cannot access other databases on the same server. This aligns with the principle of least privilege for multi-tenant isolation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a server-level firewall rule to restrict access to the tenant's IP.
Why it's wrong here
Firewall does not restrict permissions.
- ✓
Create a contained database user with db_owner role in each tenant's database and use Microsoft Entra authentication.
Why this is correct
Contained users are scoped to the database.

- ✗
Create a server-level login and assign it as db_owner on all databases.
Why it's wrong here
Server-level login can access all databases if granted.
- ✗
Create a database-level firewall rule for each tenant database.
Why it's wrong here
Firewall rules control network access, not permissions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse server-level logins with database-level contained users, assuming that assigning db_owner via a server login is sufficient for isolation, but it actually grants cross-database access.
Detailed technical explanation
How to think about this question
Contained database users in Azure SQL Database are authenticated directly against the database, bypassing the server-level login hierarchy. When using Microsoft Entra authentication, the user's identity is validated by Entra ID, and the db_owner role grants full administrative permissions only within that specific database. This design prevents lateral movement between tenant databases, as there is no server-level principal that can be used to access other databases.
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.
