Question 600

At Brookside Manufacturing, the plant software team is implementing a work-order system upgrade under requirements for planned downtime and production traceability. The team says the following incident was fixed: A generative agent automatically approves vendor payments based on free-form text without human approval. Which result BEST proves the intended fix is effective?

  1. A prompt-injection test yields a safe report and no credential access or unauthorized data disclosure.
  2. A failing agent trace identifies the specific tool and error without storing sensitive prompt contents.
  3. In tests the agent proposes an action but no payment executes until a permitted approver confirms it.
  4. Responses summarize permitted interactions and excluded confidential records never appear in tool results.

Explanation

Correct Answer

C:

In tests the agent proposes an action but no payment executes until a permitted approver confirms it. This directly tests whether the reported failure has been corrected: A generative agent automatically approves vendor payments based on free-form text without human approval. The intended action was Require a human confirmation checkpoint and deterministic amount verification before authorizing any payment write. The observed Brookside Manufacturing outcome is stronger evidence than a completed ticket or a saved configuration alone.

Incorrect Answers

A:

A prompt-injection test yields a safe report and no credential access or unauthorized data disclosure. Such evidence would validate a different change: A malicious external document instructs an agent to reveal Dataverse credentials while the agent is gathering a report. It follows the separate remedy Treat retrieved document text as untrusted data and restrict tools, secrets and prompt-following privileges at the execution boundary. The Brookside Manufacturing scenario instead reports A generative agent automatically approves vendor payments based on free-form text without human approval. The decisive observation must be: In tests the agent proposes an action but no payment executes until a permitted approver confirms it.

B:

A failing agent trace identifies the specific tool and error without storing sensitive prompt contents. Such evidence would validate a different change: A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. It follows the separate remedy Capture sanitized tool-call traces, correlation IDs, latency and exception categories in approved monitoring. The Brookside Manufacturing scenario instead reports A generative agent automatically approves vendor payments based on free-form text without human approval. The decisive observation must be: In tests the agent proposes an action but no payment executes until a permitted approver confirms it.

D:

Responses summarize permitted interactions and excluded confidential records never appear in tool results. Such evidence would validate a different change: An agent is asked to summarize internal service interactions using Work IQ data but its prompt includes pasted sensitive records. It follows the separate remedy Integrate the authorized Work IQ and Dataverse data access path with scoped identity rather than injecting entire datasets into prompts. The Brookside Manufacturing scenario instead reports A generative agent automatically approves vendor payments based on free-form text without human approval. The decisive observation must be: In tests the agent proposes an action but no payment executes until a permitted approver confirms it.

Question 601

At Silvercrest University, the research IT team is implementing a laboratory scheduling app under requirements for research data controls. The architecture review finds: A malicious external document instructs an agent to reveal Dataverse credentials while the agent is gathering a report. Which change BEST resolves this specific problem?

  1. Require a human confirmation checkpoint and deterministic amount verification before authorizing any payment write.
  2. Choose an integration architecture connecting the Foundry agent and Copilot Studio agent with explicit responsibilities and boundaries.
  3. Treat retrieved document text as untrusted data and restrict tools, secrets and prompt-following privileges at the execution boundary.
  4. Capture sanitized tool-call traces, correlation IDs, latency and exception categories in approved monitoring.

Explanation

Correct Answer

C:

Treat retrieved document text as untrusted data and restrict tools, secrets and prompt-following privileges at the execution boundary. This specifically addresses A malicious external document instructs an agent to reveal Dataverse credentials while the agent is gathering a report.
