Question 780 of 919
DP-300 Implement a secure environment Practice Question
You have an Azure SQL Database that needs to be accessed by an application with a static public IP address. You want to allow only that IP address to connect. What should you configure?
⚠ Common exam trap
A common mix-up: candidates confuse database-level firewall rules (Option D) as the correct answer, not realizing that server-level rules are the standard for IP-based access and that database-level rules require contained database users, which is an additional prerequisite not mentioned in the scenario.
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 server-level firewall rule with the application's IP.
A server-level firewall rule explicitly allows inbound connections from a specific client IP address to the Azure SQL Database logical server. Since the application has a static public IP, configuring a server-level firewall rule with that IP is the simplest and most direct method to restrict access to only that address, while still using the public endpoint.
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 virtual network rule for the database.
Why it's wrong here
VNet rules are for traffic from a specific virtual network.
- ✗
Create a private endpoint for the database.
Why it's wrong here
Private endpoint is for private IP from a VNet.
- ✓
Create a server-level firewall rule with the application's IP.
Why this is correct
Server-level firewall rules allow specific IP addresses.
- ✗
Create a database-level firewall rule with the application's IP.
Why it's wrong here
Database-level rules are not supported for single databases; use server-level.
