The correct answer is to include a Private Endpoint resource linked to the Cognitive Services account via the `privateLinkServiceId` property. This configuration assigns a private IP address from your virtual network to the Azure AI Language resource, effectively isolating it from the public internet. When you also set the resource’s `publicNetworkAccess` property to 'Disabled', all public traffic is blocked by default, and data flows exclusively over the Microsoft backbone network through Azure Private Link. On the AI-102 exam, this scenario tests your understanding of network security for Azure AI services, often appearing as a Bicep template completion task where you must choose the missing resource. A common trap is confusing a Private Endpoint with a Service Endpoint—remember that Private Endpoints use private IPs and require the `privateLinkServiceId`, while Service Endpoints do not. Memory tip: think “Private IP, Private Link” to recall that a Private Endpoint is the only resource that assigns a private IP and integrates with Private Link for blocking public access.
AI-102 Plan and manage an Azure AI solution Practice Question
This AI-102 practice question tests your understanding of plan and manage an azure ai solution. 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.
Refer to the exhibit. You are reviewing a Bicep template for deploying an Azure AI Language resource. After deployment, you need to ensure that the resource uses a private endpoint to block public access. Which additional resource should you include in the template?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A Private Endpoint resource linked to the Cognitive Services account
Option D is correct because a Private Endpoint resource, when linked to the Cognitive Services account via the `privateLinkServiceId` property, assigns a private IP address from a virtual network to the Azure AI Language resource. This blocks all public access by default when the resource's `publicNetworkAccess` property is set to 'Disabled', ensuring traffic only flows over the Microsoft backbone network through Azure Private Link.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A service endpoint for Microsoft.CognitiveServices
Why it's wrong here
Service endpoints do not block public access entirely.
✗
A virtual network peering connection
Why it's wrong here
Peering does not provide private access to Cognitive Services.
✗
A virtual network gateway
Why it's wrong here
Not needed for private endpoint.
✓
A Private Endpoint resource linked to the Cognitive Services account
Why this is correct
Private endpoint enables private access and disables public access.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse service endpoints (which only filter source traffic but leave the public endpoint active) with private endpoints (which completely remove public accessibility), leading them to incorrectly select Option A.
Detailed technical explanation
How to think about this question
Azure Private Endpoint uses a network interface (NIC) with a private IP from your VNet, leveraging DNS configuration to resolve the Cognitive Services FQDN (e.g., `your-account.cognitiveservices.azure.com`) to that private IP. Under the hood, the Private Link service uses a regional, zone-redundant connection that bypasses the public internet entirely, and the `publicNetworkAccess` property on the Cognitive Services account must be explicitly set to 'Disabled' to enforce the block. In a real-world scenario, this is critical for compliance with data residency or security policies that require no internet-exposed endpoints for sensitive AI workloads.

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
