- A
The standard API for reading data from Azure Storage accounts and databases
Why wrong: Storage APIs are data access tools — the Read API is an OCR service for extracting text from documents and images.
- B
An advanced OCR service handling multi-page PDFs, handwriting, and complex layouts with word-level coordinates
The Read API goes beyond basic OCR — multi-page, handwriting, complex layouts, and word positions — powered by deep learning.
- C
An API for reading audio content and converting it to text transcripts
Why wrong: Audio transcription is Azure AI Speech (speech-to-text) — the Read API specifically handles visual text extraction from images and documents.
- D
A feature for reading the metadata of image files stored in Azure Blob Storage
Why wrong: Blob metadata access is a storage API — the Read API applies AI to extract text content from within document images.
AI-900 Practice Question: Describe features of computer vision workloads on Azure
This AI-900 practice question tests your understanding of describe features of computer vision workloads on azure. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
What is 'Azure AI Vision's Read API' and what makes it superior for OCR?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
An advanced OCR service handling multi-page PDFs, handwriting, and complex layouts with word-level coordinates
Azure AI Vision's Read API is an advanced OCR service that extracts text from images and documents, including multi-page PDFs, handwritten text, and complex layouts. It is superior because it returns word-level bounding box coordinates and confidence scores, enabling precise text localization and structured output for downstream processing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
The standard API for reading data from Azure Storage accounts and databases
Why it's wrong here
Storage APIs are data access tools — the Read API is an OCR service for extracting text from documents and images.
- ✓

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the Read API with other Azure services like Storage APIs or Speech services, overlooking that it is specifically a computer vision OCR service for text extraction from images and documents.
Detailed technical explanation
How to think about this question
The Read API uses a deep-learning-based recognition model that processes images in parallel, returning results as a list of pages, lines, and words with bounding polygons and confidence scores. It supports over 200 languages and can handle rotated, skewed, or noisy documents, making it ideal for scenarios like invoice processing or document digitization where layout preservation is critical.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
