Issue Creating Azure AI Language Resource in Custom Question Answering Lab

Hi Pornpra Chumnanvanichkul,
This error is expected behavior in the Microsoft Applied Skills lab environment and is not caused by anything wrong in your setup.

The Applied Skills labs use a locked‑down sandbox subscription. These subscriptions have global policies applied that restrict which resource types and pricing tiers can be created. When you see the error RequestDisallowedByPolicy – Global Policy – Microsoft Applied Skills – Type 3, it means the subscription policy is blocking the request before the resource is created.

In this case, the issue is not the region but the pricing tiers being selected. Applied Skills lab subscriptions usually block paid SKUs to prevent unexpected costs.

For the Azure AI Language resource, selecting the S tier is treated as a paid option. For Custom Question Answering labs, you should use the Free F0 tier, which is enough for lab exercises and supports a limited number of documents.

For Azure Cognitive Search, the Standard S tier is almost always blocked in lab subscriptions. You need to select the Free F0 tier instead. Most Applied Skills labs are designed to work only with the free search tier.

Once both the Azure AI Language resource and Azure Cognitive Search are set to Free F0, the resource creation should go through successfully and you can continue with the lab.

You can find official guidance on Custom Question Answering and supported configurations here: https://dotnet.territoriali.olinfo.it/azure/ai-services/language-service/question-answering/overview

In short, this is a lab subscription policy limitation. Make sure both services use Free F0 pricing, and the deployment should work as expected.

I Hope this helps. Do let me know if you have any further queries.
Thankyou!

Hi Pornpra Chumnanvanichkul,

Welcome to Microsoft Q&A,

The RequestDisallowedByPolicy (Global Policy - Microsoft Applied Skills - Type 3) error is specific to the locked-down sandbox subscription provided by the Applied Skills lab environment. These lab environments run on locked-down subscriptions with pre-configured policies that only allow specific regions, SKUs, or resource types, so if your resource configuration violates those policies, the deployment fails even if it looks correct by the lab instructions.

Based on your configuration, the most likely cause is the pricing tier combination, not the region.

The two tiers to reconsider:

Azure AI Language — S (1K Calls per minute): The S tier is a paid SKU. Applied Skills lab policies commonly block paid tiers to control costs in the sandbox. Try switching to Free (F0) for the AI Language resource. For Custom Question Answering specifically, F0 supports up to 3 managed documents and is sufficient for lab exercises.

Azure Search — Standard S (50 Indexes): This is the more likely culprit. The Standard S tier for Azure Cognitive Search is expensive and almost always restricted to Microsoft lab subscriptions. Switch this to Free (F0) — it supports up to 3 indexes and is what most Applied Skills labs are designed around.
