You have the following C# method for creating Azure Cognitive Services resources programmatically.
You need to call the method to create a free Azure resource in the West US Azure region. The resource will be used to generate captions of images automatically.
Which code should you use?

  1. create_resource(client, "res1", "ComputerVision", "F0", "westus")
  2. create_resource(client, "res1", "CustomVision.Prediction", "F0", "westus")
  3. create_resource(client, "res1", "ComputerVision", "S0", "westus")
  4. create_resource(client, "res1", "CustomVision.Prediction", "S0", "westus")

Answer(s): A

Explanation:

Many of the Cognitive Services have a free tier you can use to try the service. To use the free tier, use F0 as the SKU for your resource.
There are two tiers of keys for the Custom Vision service. You can sign up for a F0 (free) or S0 (standard) subscription through the Azure portal.
Incorrect Answers:
A: There is no free tier (F0) for ComputerVision.
