AI-102 Practice Question: Implement knowledge mining and information extraction solutions
Your knowledge mining solution ingests documents from multiple tenants. Each tenant's data must be isolated and searchable only by that tenant. You have a single Azure AI Search service. How should you implement multi-tenancy?
⚠ Common exam trap
Test-takers frequently confuse data sources (which are just ingestion pipelines) with data partitioning, leading them to think separate data sources or skillsets provide isolation, when in fact only query-time filtering or separate indexes enforce tenant boundaries.

Correct answer & explanation
✓
Use a single index with a tenant ID field and filter queries by that field
Azure AI Search supports multi-tenancy within a single service by using a shared index with a tenant ID field. Each document is tagged with a tenant identifier, and queries are scoped using OData `$filter` expressions (e.g., `$filter=tenantId eq 'tenant123'`). This ensures data isolation while keeping costs low and management simple, as only one search service and one index are needed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use separate skillsets for each tenant
Why it's wrong here
Skillsets do not provide data isolation.
- ✗
Create a separate search service for each tenant
Why it's wrong here
Expensive and hard to manage.
- ✓
Use a single index with a tenant ID field and filter queries by that field
Why this is correct
Index-level security with filters is the recommended approach.
- ✗
Use separate data sources within the same index
Why it's wrong here
Data sources do not enforce tenant isolation.
