DP-300 Implement a secure environment Practice Question
You are implementing a new Azure SQL Database and need to ensure that connections from client applications are encrypted using TLS 1.2 or higher. Which server-level firewall rule setting should you configure?
⚠ Common exam trap
A common mix-up: candidates confuse network access controls (like firewall rules or service endpoints) with encryption protocol enforcement, assuming that 'Allow Azure Services' or 'Deny public network access' somehow impacts TLS version requirements.

Correct answer & explanation
✓
Set minimal TLS version to 1.2
The 'Minimal TLS version' server-level firewall rule setting enforces the minimum TLS version for encrypted connections to Azure SQL Database. By setting this to 1.2, the server will reject any connection attempts using TLS 1.0 or 1.1, ensuring all client applications use TLS 1.2 or higher. This setting is configured in the Azure portal under the 'Networking' blade of the SQL server resource.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deny public network access
Why it's wrong here
Controls network access, not TLS version.
- ✗
Enable contained database authentication
Why it's wrong here
Related to authentication, not encryption.
- ✗
Allow Azure Services and resources to access this server
Why it's wrong here
Controls access from Azure, not encryption.
- ✓
Set minimal TLS version to 1.2
Why this is correct
Enforces TLS 1.2 or higher for all connections.
