Hi,
I have found the following question in the practice assessment for AI-102:
Question:
You have an app named App1.
You plan to integrate App1 with Azure Cognitive Services.
What is a valid billing model for Cognitive Services?
Choices:
pay as you go
commitment tier
Azure reservations
Correct Answer:
Reservations is the only billing tier option for Azure virtual machines.
I am not a native english speaker, but I am fluent. This seems like a poorly formulated question. Cognitive Services has both pay as you go and commitment tiers. But from the correct answer it seems like the question should be about billing for App1 and not Cognitive Services as stated (?)
