AI-102 Plan and manage an Azure AI solution Practice Question
Your organization wants to implement a document processing pipeline that extracts text from scanned PDFs and identifies named entities. Which two Azure AI services should you use?
⚠ Common exam trap
A common mix-up: candidates confuse Azure AI Document Intelligence with Azure AI Custom Vision, thinking Custom Vision can perform OCR, but Document Intelligence is the dedicated service for document text extraction and layout analysis.

Correct answer & explanation
✓
Azure AI Language
Azure AI Document Intelligence (formerly Form Recognizer) is used to extract text from scanned PDFs via OCR, while Azure AI Language provides pre-built named entity recognition (NER) to identify entities like people, organizations, and locations. Together, they form a complete pipeline: Document Intelligence handles the image-to-text conversion, and Language processes the extracted text for entity extraction.
