The answer is Azure AI Document Intelligence. This service is specifically designed to extract structured data from scanned documents by using prebuilt models for common fields like parties, effective dates, and termination conditions, as well as custom models for unique legal clauses. On the Microsoft Azure AI Engineer Associate AI-102 exam, this question tests your ability to distinguish between services that extract data from documents versus those that analyze text or images—a common trap is confusing Azure AI Language (which handles unstructured text analytics) or Azure AI Vision (which focuses on image content) with Document Intelligence’s core OCR and field extraction capabilities. Remember that Document Intelligence is the only service that treats a scanned PDF as a structured form, not just an image or a block of text. A helpful memory tip: think “Document Intelligence” as the “form reader” that turns scanned contracts into structured JSON, while other services merely “see” or “read” without extracting key-value pairs.
AI-102 Practice Question: Implement knowledge mining and information extraction solutions
This AI-102 practice question tests your understanding of implement knowledge mining and information extraction 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 building a knowledge mining solution for a legal firm that needs to extract key clauses from thousands of scanned contract PDFs. The solution must identify parties, effective dates, and termination conditions. Which Azure AI service should you use as the primary component?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure AI Document Intelligence
Option B is correct because Azure AI Document Intelligence (formerly Form Recognizer) is designed for extracting structured information from documents using prebuilt and custom models. Option A is incorrect because Azure AI Language is for text analytics and NLP but not optimized for scanned documents. Option C is incorrect because Azure AI Search is for indexing and searching, not extraction. Option D is incorrect because Azure AI Vision is for image analysis, not document extraction.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Azure AI Document Intelligence
Why this is correct
Azure AI Document Intelligence (formerly Form Recognizer) is designed to extract data from documents, including scanned PDFs.
Clue confirmation
The clue word "primary" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Azure AI Vision
Why it's wrong here
Azure AI Vision analyzes images, not structured document content.
✗
Azure AI Language
Why it's wrong here
Azure AI Language provides text analytics but cannot extract from scanned PDFs directly.
✗
Azure AI Search
Why it's wrong here
Azure AI Search indexes data but does not perform extraction.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related AI-102 NAT questions on configuration and troubleshooting.

Variation 1. You need to implement a solution that searches through a collection of scanned invoices and extracts invoice numbers, dates, and total amounts. The solution must run on a schedule without manual intervention. Which Azure service should you use?
easy
A.Azure Bot Service
✓ B.Azure AI Document Intelligence
C.Azure AI Search with built-in skills
D.Azure AI Foundry model catalog
Why B: Option A is correct because Azure AI Document Intelligence is designed for extracting structured data from documents. Option B is for AI model deployment, not extraction. Option C is for indexing data for search. Option D is for conversational AI.
Variation 2. Your company has a large repository of scanned invoices in PDF format. You need to extract invoice number, date, total amount, and vendor name from these PDFs. Which Azure AI service should you use?
medium
A.Azure AI Language
✓ B.Azure AI Document Intelligence
C.Azure AI Search
D.Azure AI Vision
Why B: Azure AI Document Intelligence (formerly Form Recognizer) is designed for extracting structured data from forms and documents. Pre-built invoice model can extract invoice fields. Azure AI Language is for text analytics on extracted text.
