Question 15
Domain 2: Data PreparationA company has policy documents for several regions. Users should receive answers only from documents approved for their region. What should the retrieval workflow use?
Correct answer: A
Explanation
Metadata filters tied to region and access rules limit retrieval to documents tagged for a user’s region and permitted by policy. This follows the principle of filtering by document attributes before generation so users receive answers only from approved regional sources.
Why each option is right or wrong
A. Metadata filters tied to region and access rules
The retrieval step should apply document-level metadata constraints before any generation, so only region-tagged and policy-approved files are eligible for search results. In practice, this means filtering on attributes such as region and access entitlement at retrieval time, which is the standard way to enforce least-privilege access and prevent cross-region leakage; without that filter, the system could surface documents from unauthorized jurisdictions.
B. One global index with no filters
A global index without filters can return documents from unauthorized regions.
C. Random document selection
Random selection ignores document relevance, region tags, and access policy enforcement.
D. A prompt asking the model to ignore unapproved documents after they are retrieved
Prompt instructions do not reliably enforce access control after retrieval has occurred.
