AI-102 Practice Question: Implement knowledge mining and information extraction solutions

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
✓
Use Azure AI Document Intelligence layout model as a custom skill
Azure AI Document Intelligence Layout model extracts text, tables, and their structure from documents, making it suitable for preserving table structure and building a searchable knowledge base. It can be used as a custom skill in an Azure AI Search enrichment pipeline. Option A is incorrect because uploading documents directly to Azure AI Search only indexes raw text without extraction or table structure preservation. Option B is incorrect because Custom Entity Extraction in Azure AI Language focuses on identifying entities, not extracting tables or preserving structure. Option D is incorrect because Azure AI Vision OCR extracts text but not table structure, and is not designed for document layout analysis.
