AI-102 Plan and manage an Azure AI solution Practice Question
You are planning a solution that uses Azure AI Document Intelligence to process invoices. The solution must be deployed to a production environment with high availability. You need to use an Azure Resource Manager (ARM) template to deploy the Document Intelligence resource. The template must ensure that the resource is deployed to two Azure regions. What should you do?
⚠ Common exam trap
The trap here is assuming that a single Azure resource can be deployed to multiple regions by specifying multiple locations in the location property.

Correct answer & explanation
✓
Create two separate Document Intelligence resources in the ARM template, each in a different region, and use a Traffic Manager profile to distribute requests.
To achieve high availability across regions for Azure AI Document Intelligence, you must deploy multiple resources, each in a different region. An ARM template can define both resources, and you can use Azure Traffic Manager to route requests. This ensures that if one region fails, the other can handle the load. The other options either do not provide cross-region redundancy or rely on non-existent features.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the copy element in the ARM template to deploy multiple instances of the Document Intelligence resource with the same region but different names.
Why it's wrong here
The copy element allows you to create multiple instances of a resource, but they would all be deployed to the same region if you use a single location value. This does not provide cross-region redundancy. To deploy to different regions, you need to vary the location property per instance, which is possible with copy but requires an array of regions and indexing. This option does not meet the requirement of two regions.
- ✗
Deploy a single Document Intelligence resource and configure geo-replication through the Azure portal after deployment.
Why it's wrong here
Azure AI Document Intelligence does not support geo-replication as a built-in feature. You cannot enable replication through the portal. High availability typically requires deploying separate resources in different regions and using a traffic routing service. This option is invalid because the feature does not exist for this service.
- ✓
Create two separate Document Intelligence resources in the ARM template, each in a different region, and use a Traffic Manager profile to distribute requests.
Why this is correct
This approach deploys two independent Document Intelligence resources in different regions, providing high availability. Traffic Manager can route traffic based on priority or performance. This is a common pattern for multi-region deployments. The ARM template can define both resources and the Traffic Manager profile, ensuring consistent deployment. This satisfies the requirement for high availability across regions.
- ✗
Deploy the ARM template with a single Document Intelligence resource and set the location property to a variable that contains multiple regions.
Why it's wrong here
The location property of an Azure resource accepts only a single region. You cannot specify multiple regions in a single resource definition. To achieve multi-region deployment, you must deploy multiple instances or use a different approach such as Traffic Manager or Front Door for routing. This option would cause a deployment error or deploy to only one region.
