AI-102 Implement computer vision solutions Practice Question
You are designing a solution that uses Azure AI Vision to extract text from scanned invoices. The invoices vary in layout and include both printed and handwritten fields. The solution must achieve high accuracy with minimal manual labeling. Which approach should you recommend?
⚠ Common exam trap
The trap here is that candidates often overestimate the need for custom training or regex-based parsing, not realizing that Azure provides a prebuilt, high-accuracy model specifically for invoices that requires zero manual labeling.
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
✓
Use the Azure AI Document Intelligence prebuilt invoice model.
The Azure AI Document Intelligence prebuilt invoice model is specifically designed to extract common fields from invoices with high accuracy, handling both printed and handwritten text without requiring manual labeling. It uses advanced OCR and deep learning models trained on thousands of invoices, making it ideal for varied layouts and minimal setup.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the Read API to extract all text and then use a custom regex to parse fields.
Why it's wrong here
Regex is fragile for varying layouts.
- ✓
Use the Azure AI Document Intelligence prebuilt invoice model.
Why this is correct
Prebuilt invoice model handles varying layouts and mixed text.
- ✗
Train a Custom Vision object detection model to locate fields.
Why it's wrong here
Custom Vision is not optimized for document field extraction.
- ✗
Label hundreds of invoices and train a custom Azure AI Document Intelligence model.
Why it's wrong here
Requires extensive labeling; prebuilt model is better.
