Question 660
Following a proposed change in a decision-support initiative at Oakridge Insurance, the commercial systems team reports that it addressed the following need under restricted source access: An agent copies secret customer records into an external URL supplied by a retrieved document. Which observation provides the STRONGEST evidence that the change worked?
Explanation
Correct Answer
Prompt-injection trials cannot exfiltrate restricted records through allowed tools. This is the direct observable test of the intended response: Treat retrieved text as untrusted, limit tools and egress, and require authorization for data transfer. In the context of Oakridge Insurance's a decision-support initiative, it checks an actual outcome instead of treating completion of a project ticket or an untested assertion as evidence.
Incorrect Answers
An incident simulation demonstrates the team can disable risky tools and restore safely. This would instead validate the different situation: An AI service continues operating after anomalous automated tool calls with no incident procedure. It would ordinarily follow the action: Define detection, containment, escalation, and recovery processes for AI-specific incidents. It does not establish that Oakridge Insurance solved the need specified in this scenario; the relevant check is: Prompt-injection trials cannot exfiltrate restricted records through allowed tools.
Unauthorized edits and cross-team reads fail in role-based access tests. This would instead validate the different situation: A retrieval agent has administrator access to source repositories even though users need read-only excerpts. It would ordinarily follow the action: Enforce IAM least privilege and identity-aware authorization for service accounts and retrieval tools. It does not establish that Oakridge Insurance solved the need specified in this scenario; the relevant check is: Prompt-injection trials cannot exfiltrate restricted records through allowed tools.
Log sampling shows required telemetry without unnecessary sensitive values. This would instead validate the different situation: A service logs complete user prompts containing confidential data for indefinite retention. It would ordinarily follow the action: Minimize sensitive logging, restrict log access, and apply defined retention periods. It does not establish that Oakridge Insurance solved the need specified in this scenario; the relevant check is: Prompt-injection trials cannot exfiltrate restricted records through allowed tools.
