The correct answer is to add a database-level firewall rule for the IP range 192.168.1.0/24. This is because database-level firewall rules in Azure SQL Database are scoped to a single database on a logical server, allowing you to restrict access to that specific database while blocking access to all others on the same server. Server-level firewall rules, by contrast, would grant the developers access to every database on that server, which violates the requirement. On the DP-300 exam, this scenario tests your understanding of the difference between server-level and database-level firewall rules, a common trap where candidates mistakenly choose a server-level rule for granular control. Remember the memory tip: "Server-wide, database-tight"—server rules open all databases, while database rules lock down just one.
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 Azure SQL Database firewall rules. You need to allow a team of developers to connect from their office IP range (192.168.1.0/24) to a specific database. The developers should not be able to access other databases on the same logical server. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a database-level firewall rule for the IP range 192.168.1.0/24.
Database-level firewall rules in Azure SQL Database allow you to restrict access to a specific database on a logical server, rather than the entire server. By adding a rule for the IP range 192.168.1.0/24 at the database level, the developers can connect only to that database, and they will be blocked from accessing other databases on the same server. This is the correct approach because server-level rules would grant access to all databases, which violates the requirement.
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 private endpoint for the database.
Why it's wrong here
Private endpoints provide private connectivity, not IP-based access.
✗
Add a server-level firewall rule for the IP range 192.168.1.0/24.
Why it's wrong here
Server-level rules apply to all databases on the server.
✓
Add a database-level firewall rule for the IP range 192.168.1.0/24.
Why this is correct
Database-level rules restrict access to the specific database.

✗
Configure a virtual network service endpoint for the server.
Why it's wrong here
Service endpoints require VNet integration, not IP ranges.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume server-level firewall rules are sufficient for all scenarios, but the DP-300 exam tests the distinction that database-level rules are required when you need to restrict access to a specific database on a logical server.
Detailed technical explanation
How to think about this question
Database-level firewall rules are stored in the `master` database and are applied per database; they are created using the `sp_set_database_firewall_rule` stored procedure. These rules take precedence over server-level rules for the same IP range, allowing fine-grained access control. In a real-world scenario, this is critical for multi-tenant environments where different teams or customers need isolated access to their own databases on a shared server.

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.
