Question 760

At Seabrook University, a SQL RAG procedure must call a model hosted behind HTTPS. The observed constraint is: Any SQL login could exfiltrate data if broad EXEC rights are granted. What operational condition would provide the earliest useful regression warning?

  1. Monitor outbound endpoint audit events
  2. Monitor schema changes and parsing failures
  3. Monitor outbound payload policy violations
  4. Monitor anomalous tool calls and injection detections

Explanation

Correct Answer

A:

Any SQL login could exfiltrate data if broad EXEC rights are granted. Monitor outbound endpoint audit events.

Incorrect Answers

B:

“Monitor schema changes and parsing failures” concerns SQL code treats whole response envelope as plain answer; the reported problem instead is Any SQL login could exfiltrate data if broad EXEC rights are granted. Monitor outbound endpoint audit events.

C:

“Monitor outbound payload policy violations” concerns Unneeded PII would be sent to external language model; the reported problem instead is Any SQL login could exfiltrate data if broad EXEC rights are granted. Monitor outbound endpoint audit events.

D:

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

Question 762

Mountainview Realty is responsible for an Azure SQL or Microsoft SQL workload. A database sends related case records to an LLM. Operational evidence: String concatenation produces malformed JSON when text contains quotes. Which proposed change is the most suitable response to the observed constraint?

  4. Use RAG to retrieve relevant policy passages as context for generation

Explanation

Correct Answer

B:

String concatenation produces malformed JSON when text contains quotes. Use supported SQL JSON generation for structured prompt payload.
