MB-920 Practice Question: A Dynamics 365 Finance administrator configures…
Exhibit
Refer to the exhibit.
```json
{
"aiBuilder": {
"model": "InvoiceProcessing",
"fields": ["InvoiceNumber", "InvoiceDate", "TotalAmount", "VendorName"],
"confidenceThreshold": 0.8,
"fallbackAction": "ManualReview"
}
}
```A Dynamics 365 Finance administrator configures an AI Builder model for invoice processing with the above JSON. After deployment, the system correctly extracts data from 90% of invoices but sends 10% to manual review. What is the most likely reason for the manual review?
⚠ Common exam trap
Many exam-takers assume the threshold is 0.9 (option C) because it is a common default in some AI models, but the JSON explicitly shows 0.8, and the question tests attention to the configuration details.
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
✓
The confidence score for extracted fields is below the threshold of 0.8 for those invoices
The JSON configuration sets a confidence threshold of 0.8 for extracted fields. When the model's confidence in the extracted data falls below this threshold, the system automatically routes the invoice to manual review. This is the standard behavior for AI Builder invoice processing models to ensure accuracy and reduce errors from low-confidence predictions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The invoice images are too blurry for the model to read
Why it's wrong here
While blurry images could reduce confidence, the manual review is triggered by confidence threshold, not directly by blur.
- ✓
The confidence score for extracted fields is below the threshold of 0.8 for those invoices
Why this is correct
Exactly: the model's confidence is below 0.8, triggering the fallback action.
- ✗
The model extracts all fields but with confidence below 0.9
Why it's wrong here
The threshold is 0.8, not 0.9; below 0.8 triggers manual review.
- ✗
The invoice contains multiple pages that need to be split
Why it's wrong here
The exhibit does not mention split; fallback is manual review, not splitting.
