Question 2
Domain 1: Plan and Manage an Azure AI SolutionYou need to select an Azure AI service tier for a production language processing workload. The workload processes 10 million characters per month. The Free tier supports only 5,000 characters per month. Which tier should you select, and what is the cost model?
Correct answer: B
Explanation
Select the Standard (S) tier because the workload needs 10 million characters per month, far above the Free tier limit of "5,000 characters per month." Standard tier uses a pay-per-call model, so charges are based on the number of characters processed rather than a fixed monthly allowance.
Why each option is right or wrong
A. Free (F0) — upgrade to F1 when volume increases
B. Standard (S) — pay-per-call pricing based on characters processed
The Free tier is capped at 5,000 characters per month, so a workload processing 10,000,000 characters monthly exceeds that limit by a factor of 2,000 and requires the paid production tier. Azure AI Language uses the Standard (S) tier for production usage, with billing based on the number of characters processed in each call rather than a flat subscription fee.
C. Premium (P) — reserved capacity with flat monthly fee
D. Enterprise (E) — unlimited processing with SLA guarantee
