Question 33
Domain 3: Describe Azure AI services for computer vision and document processingWhich of the following is NOT a way to use Azure AI Vision's Read API?
Correct answer: C
Explanation
Azure AI Vision’s Read API is used to extract text from images and documents through supported request formats and endpoints, not through GraphQL. GraphQL is a query language for APIs, so it is not a way to use the Read API.
Why each option is right or wrong
A. Vision Studio
B. REST API
C. GraphQL
Azure AI Vision’s Read API is invoked through the service’s REST endpoint, typically by submitting an image URL or binary image data in an HTTP request and then polling the operation result; it is not exposed as a GraphQL interface. GraphQL is a separate API query language and transport pattern, so it does not match the documented Read API usage model for OCR/text extraction.
D. Software Development Kits (SDKs)
