Question 770

A database engineer at Briarfield Foods is investigating this case: A retrieved policy document contains instructions to ignore system rules. The relevant finding is: Untrusted document text could influence agent behavior. What operational condition would provide the earliest useful regression warning?

  1. Monitor outbound endpoint audit events
  2. Monitor hallucination and missing citations
  3. Monitor anomalous tool calls and injection detections
  4. Monitor malformed request rejections and payload size

Explanation

Correct Answer

C:

Untrusted document text could influence agent behavior. Monitor anomalous tool calls and injection detections.

Incorrect Answers

A:

“Monitor outbound endpoint audit events” concerns Any SQL login could exfiltrate data if broad EXEC rights are granted; the reported problem instead is Untrusted document text could influence agent behavior. Monitor anomalous tool calls and injection detections.

B:

“Monitor hallucination and missing citations” concerns Model alone invents rules not in corporate source; the reported problem instead is Untrusted document text could influence agent behavior. Monitor anomalous tool calls and injection detections.

D:

“Monitor malformed request rejections and payload size” concerns String concatenation produces malformed JSON when text contains quotes; the reported problem instead is Untrusted document text could influence agent behavior. Monitor anomalous tool calls and injection detections.

Question 771
