Quick Answer
The correct answer is to create a Translator resource with a private endpoint and disable public network access. This configuration ensures that all traffic to Azure AI Translator flows through a private IP address within your virtual network, never traversing the public internet, which guarantees that confidential data remains within the specified Azure region for data residency compliance. On the Microsoft Azure AI Engineer Associate AI-102 exam, this scenario tests your understanding of network isolation for cognitive services, often appearing as a trap where candidates mistakenly choose a service endpoint or a firewall rule alone, which do not fully prevent data from leaving the region. The key concept is that a private endpoint binds the service to your VNet, while disabling public access enforces that no data can egress through the public endpoint. Remember the memory tip: “Private locks the path, public locks the door”—private endpoint secures the route, disabling public access seals the exit.
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.
You are designing a solution that uses Azure AI Translator to translate customer support tickets. The solution must handle confidential data and ensure no data leaves the specified Azure region. What should you do?
Enable customer-managed keys and disable logging
Why wrong: Does not ensure data stays in region.
Use the global Translator endpoint
Why wrong: Global endpoint may process data in different regions.
Create a Translator resource with a private endpoint and disable public network access
Keeps data within the region and private network.
Use the S1 pricing tier to ensure regional processing
Why wrong: Pricing tier does not affect data residency.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a Translator resource with a private endpoint and disable public network access
Option C is correct because using a private endpoint ensures that all traffic to the Translator resource stays within the Azure virtual network and never traverses the public internet, while disabling public network access enforces that no data can leave the specified Azure region. This combination meets the requirement for handling confidential data with regional data residency guarantees.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Enable customer-managed keys and disable logging
Why it's wrong here
Does not ensure data stays in region.
Use the global Translator endpoint
Why it's wrong here
Global endpoint may process data in different regions.
Create a Translator resource with a private endpoint and disable public network access
Why this is correct
Keeps data within the region and private network.

Use the S1 pricing tier to ensure regional processing
Why it's wrong here
Pricing tier does not affect data residency.
Common exam traps
The trap here is that candidates often confuse encryption (CMK) or pricing tiers with network-level data residency controls, failing to realize that only private endpoints combined with disabled public access can guarantee data never leaves the specified region.
Detailed technical explanation
Azure AI Translator private endpoints use Azure Private Link to assign a private IP address from your virtual network to the Translator resource, ensuring all API calls resolve within the VNet and bypass the public endpoint. Disabling public network access at the resource level (via the 'Public network access' setting) blocks any inbound traffic from the internet, even if a private endpoint is also configured. This architecture is critical for compliance with regulations like GDPR or HIPAA that mandate data residency within a specific Azure region.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
