AI-102 Plan and manage an Azure AI solution Practice Question
You need to restrict access to an Azure AI Language resource so that only a specific virtual network can call the endpoint. Which configuration should you use?
⚠ Common exam trap
Many candidates confuse network-level access controls (service/private endpoints) with authentication mechanisms (keys, managed identities) or IP-based firewalls, mistakenly believing that rotating keys or using managed identities can restrict network access, or that a VNet's public IP range is the same as the VNet's internal address space.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable a service endpoint or private endpoint for the resource
Azure AI Language resources can be isolated to a specific virtual network by enabling either a service endpoint (via the Microsoft.CognitiveServices service tag) or a private endpoint (using Azure Private Link). This configuration ensures that only traffic originating from the designated VNet can reach the resource's endpoint, effectively blocking all public internet access. Service endpoints provide a direct, optimized route from the VNet to the resource, while private endpoints assign a private IP from the VNet to the resource, making it accessible only within the VNet.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rotate the shared access keys
Why it's wrong here
Shared access keys are for authorization, not network restriction.
- ✓
Enable a service endpoint or private endpoint for the resource
Why this is correct
Service endpoints and private endpoints restrict access to specific VNets.
- ✗
Assign a managed identity to the resource
Why it's wrong here
Managed identity is for authentication, not network access control.
- ✗
Configure an IP firewall rule with the VNet's public IP range
Why it's wrong here
IP firewall is less secure and not the best practice for VNet restriction.
