The answer is to use the Azure AI Document Intelligence prebuilt invoice model. This is correct because the prebuilt invoice model is specifically designed to extract printed and handwritten fields from invoices with varying layouts, leveraging deep learning to identify key-value pairs and table data without requiring manual labeling. On the AI-102 exam, this question tests your understanding of when to use specialized document intelligence services versus general OCR or custom models; a common trap is confusing the Read API, which extracts raw text but not structured fields, with Document Intelligence’s field extraction capabilities. Remember the memory tip: “Read reads, but Invoice extracts”—the Read API gives you all the words, while the prebuilt invoice model gives you the specific fields like total, date, and vendor name, even when handwritten.
AI-102 Implement computer vision solutions Practice Question
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.
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?
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.
Option D is correct because Azure AI Document Intelligence (formerly Form Recognizer) is designed for extracting fields from documents with varying layouts and supports both printed and handwritten text. Option A is wrong because the Read API extracts all text but does not extract specific fields. Option B is wrong because Custom Vision is for object detection, not document analysis. Option C is wrong because it requires significant manual labeling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
