DP-300 Implement a secure environment Practice Question
You need to ensure that only specific Azure services can access your Azure SQL Database server. You want to allow traffic from Azure services but block all other traffic. What should you configure?
⚠ Common exam trap
It's easy for candidates to confuse the 'Allow Azure Services' rule with a generic 0.0.0.0 rule, leading candidates to think they need to add 0.0.0.0 to allow Azure traffic, when in fact the Azure services rule is a distinct mechanism that does not require explicit IP entries.

Correct answer & explanation
✓
Set the firewall rule 'Allow Azure Services and resources to access this server' to ON and remove all other IP rules.
Setting the 'Allow Azure Services and resources to access this server' firewall rule to ON enables a special rule that permits traffic from all Azure datacenter IP ranges, while removing all other IP rules ensures no other external traffic can reach the server. This configuration meets the requirement to allow only Azure services and block all other traffic, as the Azure services rule is a blanket allow for Azure-originated connections without needing specific IP addresses.
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 firewall rule 'Allow Azure Services and resources to access this server' to ON and remove all other IP rules.
Why this is correct
This allows only Azure services.
- ✗
Set the firewall rule 'Allow Azure Services and resources to access this server' to OFF and add a rule for 0.0.0.0.
Why it's wrong here
This would allow all traffic, not just Azure services.
- ✗
Set firewall rules to deny all IP addresses.
Why it's wrong here
This would block all traffic, including Azure services.
- ✗
Set the firewall rule 'Allow Azure Services and resources to access this server' to ON and add a rule for 0.0.0.0.
Why it's wrong here
Adding 0.0.0.0 allows all Azure IPs, but it's redundant.
