Question 790
An audit of the proposed fix for Beacon Health Network requires a specific controlled check. The issue under review is: A customer assistant includes complete account identifiers in LLM prompts although the response requires only purchase category. Which independently observable result best verifies that the remediation works?
Explanation
Correct Answer
Captured test requests contain only approved data fields and a secret-marker test never appears in model inputs. This controlled observation specifically validates the proposed remedy: Minimize and redact sensitive prompt fields before inference, with access-control and retention policies applied. It addresses the documented failure at Beacon Health Network: A customer assistant includes complete account identifiers in LLM prompts although the response requires only purchase category.
Incorrect Answers
A developer outside the release role cannot replace the artifact, while the expected digest loads successfully. This is evidence for a different corrective change: Enforce least-privilege artifact permissions, immutable versioning, and integrity checks before model deployment. That other change addresses: A trained model is saved in a broadly writable bucket where unrelated developers can replace weights without authorization. It does not validate the specific Beacon Health Network remediation for: A customer assistant includes complete account identifiers in LLM prompts although the response requires only purchase category. The necessary check instead is: Captured test requests contain only approved data fields and a secret-marker test never appears in model inputs.
Authorized feature reads succeed and cross-team dataset access attempts are denied in the audit trail. This is evidence for a different corrective change: Restrict inference service access to its exact datasets and serving resources using narrowly scoped identities. That other change addresses: A production inference identity can list all organization datasets although it only requires one approved feature view. It does not validate the specific Beacon Health Network remediation for: A customer assistant includes complete account identifiers in LLM prompts although the response requires only purchase category. The necessary check instead is: Captured test requests contain only approved data fields and a secret-marker test never appears in model inputs.
Adversarial requests are blocked or constrained before protected tool invocation, with auditable policy decisions. This is evidence for a different corrective change: Integrate appropriate Model Armor or supported safety and prompt-risk checks alongside least-privilege tool boundaries. That other change addresses: An enterprise agent passes unsanitized untrusted user prompts to sensitive tools with no central policy enforcement. It does not validate the specific Beacon Health Network remediation for: A customer assistant includes complete account identifiers in LLM prompts although the response requires only purchase category. The necessary check instead is: Captured test requests contain only approved data fields and a secret-marker test never appears in model inputs.
