Quick Answer
The correct answer is a Private Endpoint for Azure SQL and a Private DNS configuration for the privatelink SQL zone. A Private Endpoint assigns a private IP from your virtual network directly to the Azure SQL logical server, enabling the App Service to connect over a private IP without exposing the database to the public internet. The Private DNS zone, specifically privatelink.database.windows.net, ensures that the SQL server’s FQDN resolves to that private IP instead of a public one, making the connection fully private and secure. On the AZ-500 exam, this scenario tests your understanding of network segmentation and data exfiltration prevention—a common trap is forgetting that without the Private DNS zone, the endpoint will still attempt public DNS resolution, breaking the private connection. A key memory tip: think of the Private Endpoint as the “door” into your VNet, and the Private DNS zone as the “address book” that directs traffic to that door.
This AZ-500 practice question tests your understanding of secure networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A web app uses Azure App Service and must access Azure SQL over a private IP without exposing SQL to the public internet. Which two components are required?
Private Endpoint for Azure SQL
Correct for the stated requirement.
Inbound NAT rule on Azure Load Balancer
Why wrong: This does not meet the stated requirement as directly as the correct option.
DDoS Protection Basic only
Why wrong: This does not meet the stated requirement as directly as the correct option.
Private DNS configuration for the privatelink SQL zone
Correct for the stated requirement.

Correct answer & explanation
Private Endpoint for Azure SQL
A is correct because a Private Endpoint for Azure SQL assigns a private IP from your virtual network to the Azure SQL logical server, allowing the App Service to connect over a private IP without exposing the database to the public internet. This is the core component that brings the Azure SQL service into your virtual network privately.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often think a Load Balancer or DDoS protection is needed for private connectivity, but the actual requirement is a Private Endpoint paired with proper Private DNS resolution to avoid public internet exposure.
Detailed technical explanation
Private Endpoints use Azure Private Link to map the Azure SQL logical server to a private IP in your virtual network, and traffic flows over the Microsoft backbone network, not the public internet. The Private DNS configuration (option D) is required to resolve the Azure SQL FQDN (e.g., server.database.windows.net) to the private IP via the privatelink.database.windows.net zone, ensuring consistent private connectivity from the App Service without custom DNS servers.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
