This AI-102 practice question tests your understanding of implement computer vision solutions. 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.
Which TWO Azure AI services can be used to extract text from images?
Azure AI Face
Why wrong: Face API detects faces.
Azure AI Document Intelligence
Document Intelligence extracts text from documents.
Azure AI Video Indexer
Why wrong: Video Indexer works with video, not static images.
Azure AI Computer Vision
Computer Vision includes OCR capabilities.
Azure AI Custom Vision
Why wrong: Custom Vision does not extract text.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure AI Document Intelligence
Azure AI Document Intelligence (formerly Form Recognizer) includes the Read OCR engine that extracts printed and handwritten text from images and documents. Azure AI Computer Vision provides the OCR API (optical character recognition) which can extract text from images, including both printed and handwritten text, and supports multiple languages. Both services are designed specifically for text extraction from visual content.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure AI Face
Why it's wrong here
Face API detects faces.
Azure AI Document Intelligence

Azure AI Custom Vision
Why it's wrong here
Custom Vision does not extract text.
Common exam traps
The trap here is that candidates may confuse Azure AI Video Indexer's ability to extract text from video frames as a primary image text extraction service, but it is designed for video analysis and indexing, not standalone image text extraction.
Detailed technical explanation
Under the hood, Azure AI Document Intelligence uses the Read OCR model (based on the latest Transformer-based architecture) that can extract text from complex layouts, tables, and handwritten content. Azure AI Computer Vision's OCR API leverages the same underlying OCR engine but is accessed via a different endpoint and is optimized for general image text extraction. Both services return bounding box coordinates and confidence scores for each detected text element, enabling downstream processing like text search or document digitization.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
