Question 808 of 945
AI-102 Practice Question: Implement natural language processing solutions
A developer is creating a custom question answering project in Azure AI Language. The knowledge base contains product manuals in PDF format. Which step is essential before importing the PDFs?
⚠ Common exam trap
The trap here is that candidates might assume creating an Azure AI Search index is required because custom question answering uses search under the hood, but the Azure AI Language service manages its own index automatically, making Option B a distractor that tests knowledge of Azure AI Language service boundaries.

Correct answer & explanation
✓
Ensure PDFs are in a supported format and accessible
Before importing PDFs into a custom question answering project in Azure AI Language, the essential step is to ensure the PDFs are in a supported format (e.g., searchable PDF, not scanned images without OCR) and accessible via a valid URL or local path. This is because the import process relies on the service being able to read and extract text from the documents; unsupported or inaccessible files will cause the import to fail.
