DP-300 Implement a secure environment Practice Question
You have an Azure SQL Database that uses a firewall rule allowing access from a specific range of IP addresses. A developer reports that they cannot connect from a new IP address that falls outside the allowed range. You need to temporarily allow the developer's IP address for 24 hours without affecting existing rules. What should you do?
⚠ Common exam trap
Many exam-takers confuse server-level firewall rules with database-level firewall rules, incorrectly assuming that database-level rules exist in Azure SQL Database (they do not), or they think updating the existing range is acceptable, missing the requirement to leave existing rules unchanged.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a new firewall rule at the server level that allows the developer's IP address.
Azure SQL Database firewall rules are configured at the server level (the logical server) to control inbound access. Adding a new server-level firewall rule for the developer's specific IP address allows temporary access without modifying or removing the existing range-based rule. This approach is the standard method for granting time-limited access to a single IP while preserving all other firewall configurations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a point-to-site VPN connection for the developer.
Why it's wrong here
A point-to-site VPN would establish a secure tunnel into the Azure virtual network, but the scenario requires only a temporary IP-based firewall exception for the developer's client address. The VPN does not modify the SQL Database firewall rules, so the developer's new IP would still be blocked by the existing range restriction. This option is tempting because a VPN is commonly used to grant remote access to Azure resources securely, and it would be the correct choice if the requirement were to bypass public-network exposure entirely rather than adjust a specific IP-based firewall rule.
- ✓
Add a new firewall rule at the server level that allows the developer's IP address.
Why this is correct
New rule allows the specific IP without affecting existing rules.
- ✗
Update the existing firewall rule to include the developer's IP address.
Why it's wrong here
This would change the allowed range and might grant access to unintended IPs.
- ✗
Modify the database-level firewall rule to include the developer's IP.
Why it's wrong here
Azure SQL Database uses server-level firewall rules; database-level rules are for contained databases but not typically used.
