Microsoft DP-800 Practice Test 78
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?
- Monitor outbound endpoint audit events
- Monitor hallucination and missing citations
- Monitor anomalous tool calls and injection detections
- 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.
