- A
Automatically generating new document templates from existing forms
Why wrong: Template creation is document design — custom extraction models learn to extract specific fields from your existing document types.
- B
Training on your labeled documents to extract business-specific fields not covered by prebuilt models
Custom extraction models handle unique business forms — labeled with your specific field names to train field extraction for your document types.
- C
Translating documents into multiple languages simultaneously
Why wrong: Document translation is Azure AI Translator's capability — custom extraction extracts structured data from documents.
- D
Redacting sensitive information from documents automatically
Why wrong: PII redaction is a separate capability — custom extraction models extract specific field values from business forms.
Quick Answer
The correct answer is that Azure AI Document Intelligence’s custom extraction model is used for training on your labeled documents to extract business-specific fields not covered by prebuilt models. This is correct because the service allows you to upload your own forms—such as specialized invoices, contracts, or medical records—and manually label the unique data fields you need, like “policy number” or “diagnosis code,” which standard prebuilt models cannot recognize. On the AI-900 exam, this concept tests your understanding of when to choose custom over prebuilt models; a common trap is assuming prebuilt models can handle any document type, but they only cover common fields like dates and totals. Remember that custom extraction is your go-to for domain-specific data that isn’t universally standardized. A helpful memory tip: think “custom for the uncommon”—if your business form has a field your competitor’s doesn’t, you need a custom extraction model.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Training on your labeled documents to extract business-specific fields not covered by prebuilt models
Azure AI Document Intelligence's custom extraction model is correct because it allows you to train a model on your own labeled documents to extract fields that are specific to your business domain and not covered by prebuilt models. This is essential for processing specialized forms like invoices, contracts, or medical records that have unique data fields.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse custom extraction models with template generation or translation, assuming Document Intelligence can create templates or translate text, when in reality it is strictly for extraction and classification of document content.
Detailed technical explanation
How to think about this question
Under the hood, custom extraction models use a combination of optical character recognition (OCR) and deep learning to identify and extract key-value pairs, tables, and selection marks from documents. The model is trained on a set of labeled documents where you manually tag the fields you want to extract, and it learns to generalize to new documents. In a real-world scenario, a healthcare provider could train a custom model to extract patient ID, diagnosis codes, and treatment dates from medical forms that prebuilt models cannot handle.
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.
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.
