DP-300 Plan and implement data platform resources Practice Question
A company plans to deploy Azure SQL Database in a new region. They require that the database be accessible only from a specific set of Azure virtual machines in the same region. What should the DBA configure?
⚠ Common exam trap
Test-takers frequently confuse private endpoints with service endpoints, assuming a private endpoint alone provides network-level access control, when in fact it only provides a private IP connection and still requires explicit firewall rules to restrict which VMs can use it.

Correct answer & explanation
✓
Configure a VNet service endpoint and a firewall rule for the VNet subnet
A VNet service endpoint extends your virtual network private address space and the identity of your VNet to the Azure SQL Database service over a direct connection. By combining a service endpoint on the subnet with a firewall rule that allows traffic only from that specific VNet/subnet, you restrict access exclusively to Azure VMs in that subnet, meeting the requirement without exposing the database to the public internet.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a private endpoint only
Why it's wrong here
Private endpoint requires additional configuration and is not necessary if VMs are in the same region.
- ✓
Configure a VNet service endpoint and a firewall rule for the VNet subnet
Why this is correct
This restricts access to the specified VNet.
- ✗
Configure a point-to-site VPN
Why it's wrong here
Point-to-site is for individual client connections, not VMs.
- ✗
Set the firewall to allow Azure services and resources to access the server
Why it's wrong here
This allows all Azure services, not just specific VMs.
