The correct answer is to train a custom document extraction model using labeled samples of poor-quality scans and different layouts. This works because Azure AI Document Intelligence’s custom model capability learns directly from your specific degraded images and varied document structures, adapting its feature extraction to handle noise, blur, and skew that prebuilt models cannot reliably process. On the AI-102 exam, this scenario tests your understanding of when to move from prebuilt to custom models—a common trap is choosing to preprocess scans or use OCR enhancement, which still relies on a model not trained on your data. The key insight is that custom models, trained with labeled examples, improve accuracy without manual intervention by internalizing the exact quality issues and layout variations. Memory tip: “Custom for crummy, prebuilt for pristine”—if your scans are poor or layouts vary, always train a custom model.
AI-102 Plan and manage an Azure AI solution Practice Question
This AI-102 practice question tests your understanding of plan and manage an azure ai solution. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A financial services company uses Azure AI Document Intelligence to process loan applications. The solution extracts data from uploaded PDFs and stores it in Azure Cosmos DB. Recently, extraction errors increased due to poor-quality scans. The company needs to improve accuracy without manual intervention. The solution must also handle varying document layouts. You need to recommend a plan. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Train a custom document extraction model using labeled samples of poor-quality scans and different layouts.
Option D is correct because training a custom document extraction model using labeled samples of poor-quality scans and varying layouts directly addresses the root cause of extraction errors. Azure AI Document Intelligence's custom model capability allows you to train on specific document types and quality issues, improving accuracy without manual intervention. This approach adapts to the company's need to handle diverse layouts and degraded image quality, which prebuilt models cannot reliably manage.
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.
✗
Increase the throughput (TPS) of the Document Intelligence resource.
Why it's wrong here
Throughput affects performance, not accuracy.
✗
Enable OCR enhancement in Document Intelligence.
Why it's wrong here
OCR is already part of Document Intelligence; the issue is extraction accuracy, not OCR.
✗
Switch to Azure AI Language for entity extraction.
Why it's wrong here
Language is for text analytics, not document layout extraction.
✓
Train a custom document extraction model using labeled samples of poor-quality scans and different layouts.
Why this is correct
Custom models learn from specific examples, improving accuracy on varied layouts and quality.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse throughput scaling (Option A) or generic OCR enhancement (Option B) with actual model improvement, overlooking that only custom training can adapt to specific data quality issues and layout variations.
Detailed technical explanation
How to think about this question
Custom document extraction models in Azure AI Document Intelligence use transfer learning on a base model, requiring as few as five labeled samples per field to start. The training process includes layout analysis and OCR preprocessing, allowing the model to learn features like skewed text, low contrast, and non-standard table structures. In practice, a financial services company could label 20-30 poor-quality loan applications to significantly reduce extraction errors, while prebuilt models would fail on such degraded inputs.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
