AI-103 Plan And Manage AN Azure AI Solution Practice Question
You are designing a secure hybrid network architecture for an Azure OpenAI resource. Virtual machines inside a spoke virtual network must access the OpenAI service via a Private Endpoint. Additionally, domain name resolution must rely on an enterprise private DNS server hosted on-premises connected via ExpressRoute. Which DNS zone must you configure in Azure?

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
privatelink.openai.azure.com Private DNS zone
Why this is correct
Azure private endpoints for OpenAI require the 'privatelink.openai.azure.com' DNS zone to resolve the private IP address correctly.
- ✗
privatelink.cognitiveservices.azure.com Private DNS zone
Why it's wrong here
While multi-service accounts use cognitiveservices, specific OpenAI endpoints use the dedicated openai.azure.com privatelink zone.
- ✗
azurewebsites.net public DNS zone
Why it's wrong here
Azure OpenAI endpoints do not use azurewebsites.net domains.
- ✗
cognitiveservices.azure.com public DNS zone
Why it's wrong here
Public DNS zones cannot be customized for private IP resolution without split-horizon DNS or private DNS zones.
