AI-103 Computer Vision Practice Question
You are configuring a secure enterprise architecture where Azure AI Vision calls must not traverse the public internet. You create a private endpoint for your Azure AI Services resource in your Virtual Network. Which DNS configuration step is required for client applications within the VNet to resolve the private endpoint correctly?
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
✓
Configure Azure Private DNS zones corresponding to the cognitive services DNS zone and link it to your VNet.
When configuring private endpoints for Azure AI Services, you must update or create Private DNS zones (e.g., `privatelink.cognitiveservices.azure.com`) to map the resource FQDN to the private IP address.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add the endpoint IP to the local hosts file of every Azure AI Vision instance.
Why it's wrong here
Manual hosts file updates are unmaintainable and not a cloud-native practice.
- ✓
Configure Azure Private DNS zones corresponding to the cognitive services DNS zone and link it to your VNet.
Why this is correct
Private DNS zones ensure that DNS queries within the VNet resolve the service endpoint to its assigned private IP address.
- ✗
Configure public DNS records on your corporate DNS server to point to the public IP.
Why it's wrong here
Public IP routing defeats the purpose of keeping traffic off the public internet.
- ✗
Modify the routing table to drop all DNS traffic.
Why it's wrong here
Dropping DNS traffic would prevent any name resolution.
