AI-102 Implement computer vision solutions Practice Question
Which TWO Azure services can be used to perform optical character recognition (OCR) on documents? (Select two.)
⚠ Common exam trap
Many exam-takers assume only Azure AI Vision (the Computer Vision service) can perform OCR, forgetting that Azure AI Document Intelligence also provides OCR as part of its document analysis capabilities, and both services are valid for OCR tasks depending on the scenario.
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
✓
Azure AI Document Intelligence
Azure AI Document Intelligence (option C) is correct because it is the Azure service purpose-built for document processing, and its prebuilt Read and Layout models extract printed and handwritten text from documents and images using OCR. Azure AI Vision (option E) is also correct because its Image Analysis and Read capabilities include an OCR engine that extracts text from images and documents via the Read API. Azure AI Metrics Advisor (option A) is an anomaly-detection service for time-series data and performs no OCR. Azure AI Language (option B) provides natural language processing such as sentiment analysis, key phrase extraction, and entity recognition, not optical character recognition. Azure AI Personalizer (option D) is a reinforcement-learning-based recommendation service and has no OCR functionality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure AI Metrics Advisor
Why it's wrong here
Azure AI Metrics Advisor performs anomaly detection on time-series metrics and alerts on deviations; it has no image-processing pipeline for extracting text. It would be correct for monitoring business or telemetry data streams, not for reading documents.
- ✗
Azure AI Language
Why it's wrong here
Azure AI Language handles text analytics such as entity recognition, sentiment and question answering; it consumes text, not images, so it cannot extract characters from scanned documents. It would be correct for analysing text already produced by an OCR service.
- ✓
Azure AI Document Intelligence
Why this is correct
Document Intelligence provides prebuilt and custom OCR models that read printed and handwritten text from documents, returning structured layout, key-value pairs and tables. This satisfies the scenario's requirement to perform optical character recognition on documents, going beyond simple text extraction.
- ✗
Azure AI Personalizer
Why it's wrong here
Azure AI Personalizer is a reinforcement-learning service that ranks content to personalise user experiences; it processes interaction and reward data, not document images. It would be correct for choosing which product or article to surface to a user.
- ✓
Azure AI Vision
Why this is correct
Azure AI Vision's Read API performs OCR on images and document scans, extracting printed and handwritten text via the Image Analysis or Read operation. This directly satisfies the requirement to perform optical character recognition on documents using a general-purpose vision service.
