AI-102 Practice Question: Implement knowledge mining and information extraction solutions
You are building a knowledge mining solution that uses Azure Cognitive Search and Azure AI Language. The solution must extract key phrases and detect the language of documents. Which THREE components are required?
⚠ Common exam trap
Watch out — candidates often assume a custom skill is needed to merge multiple skill outputs, when in fact outputFieldMappings in the indexer configuration handle the routing of each skill's output to separate index fields without custom code.
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
✓
A search index that contains fields for the extracted data.
A search index is the destination where extracted data (key phrases and language) must be stored for querying. Without an index, the extracted information has no structured location to be persisted and made searchable. The index schema must include fields specifically mapped to the output of the skillset's Key Phrase Extraction and Language Detection skills.

A search index that contains fields for the extracted data.
Why this is correct
The index stores the enriched content.
- ✓
A skillset that includes the built-in Key Phrase Extraction and Language Detection skills.
Why this is correct
These skills are needed for extraction.
- ✓
A data source that points to the document store.
Why this is correct
Documents need to be accessed via a data source.
- ✗
An indexer that runs on a schedule.
Why it's wrong here
An indexer is required but not listed; this option is a schedule, not the indexer itself.
