Question 645 of 919
DP-300 Plan and implement data platform resources Practice Question
You are deploying Azure SQL Database for a new application. You need to ensure that connections from Azure services use a private IP address and do not traverse the public internet. What should you configure?
⚠ Common exam trap
Many candidates confuse Virtual Network service endpoints (which still use the public endpoint and do not provide a private IP) with Private Link (which provides a true private IP), or incorrectly assume Azure SQL Database can be deployed inside a VNet like a managed instance.
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
✓
Use Azure Private Link for Azure SQL Database
Azure Private Link creates a private endpoint in a virtual network, mapping the Azure SQL Database logical server to a private IP address within that VNet. Traffic from Azure services (e.g., VMs, App Service) to the database uses Microsoft's backbone network via the private endpoint, never traversing the public internet. This meets the requirement for private, non-internet-routed connectivity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Virtual Network service endpoints for Azure SQL Database
Why it's wrong here
Service endpoints still use public IPs but are secured to the VNet.
- ✓
Use Azure Private Link for Azure SQL Database
Why this is correct
Private Link uses private IP addresses in your VNet.
- ✗
Configure the Azure SQL Database firewall to allow Azure services
Why it's wrong here
This still uses public endpoints.
- ✗
Deploy Azure SQL Database inside a virtual network
Why it's wrong here
Azure SQL Database is a PaaS service and cannot be deployed inside a VNet.
