Question 180
In a Cisco AI Technical Practitioner study scenario, the team discovers: An HR RAG system copies personnel evaluations into a shared vector index and allows every employee to retrieve semantically similar confidential review passages. Which underlying AI system principle explains these observations?
Explanation
Correct Answer
The technical basis is: Indexing sensitive text creates another protected representation of that information; source ACLs do not automatically propagate into vector retrieval permissions. Resolve this through: Carry authorized document and identity access labels into index metadata and enforce them at retrieval and source-link resolution. The expected evidence is: An HR reviewer retrieves their approved records while a standard employee's similar query cannot reveal protected evaluation excerpts.
Incorrect Answers
Automation does not transfer responsibility away from organizational owners, and an ungoverned approval workflow lacks accountability and auditability. “Assign named business and technical owners, defined risk thresholds and human escalation for exceptions, with logged decisions and policy revisions” would remedy that alternative situation, but it would not correct the present issue: indexing sensitive text creates another protected representation of that information; source ACLs do not automatically propagate into vector retrieval permissions.
“Complete an approved AI impact assessment with security, privacy and business owners, then apply controls for the feature's decision scope” is the supported response when AI governance needs an identified use case, impact tier and risk controls before deployment; a successful integration test does not establish acceptable risk. Here the decisive response is “Carry authorized document and identity access labels into index metadata and enforce them at retrieval and source-link resolution”, so that different intervention does not meet the stated requirement.
Synthetic media can mimic recognizable voices, so audio resemblance alone is not proof of origin or authority for a corporate instruction. “Require an independently authenticated communication channel and verified approval record before acting on high-impact announcements” applies to that other condition. The reported evidence is an HR RAG system copies personnel evaluations into a shared vector index and allows every employee to retrieve semantically similar confidential review passages; this alternative would address the wrong dependency.
