Question 610
At Timberline Foods, the supply-chain systems team is implementing a vendor onboarding project under requirements for continuous approved supplier status. After the proposed change, the release reviewer requires evidence for: A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. Which result BEST proves the intended fix is effective?
Explanation
Correct Answer
A failing agent trace identifies the specific tool and error without storing sensitive prompt contents. This directly tests whether the reported failure has been corrected: A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. The intended action was Capture sanitized tool-call traces, correlation IDs, latency and exception categories in approved monitoring. The observed Timberline Foods outcome is stronger evidence than a completed ticket or a saved configuration alone.
Incorrect Answers
Read-only users cannot invoke deletion even when the agent constructs a technically valid tool call. Such evidence would validate a different change: A Foundry tool can delete rows using a tenant-wide service identity even when an end user has read-only Dataverse access. It follows the separate remedy Enforce least-privilege authorization at the MCP tool boundary and restrict destructive operations to appropriate identities. The Timberline Foods scenario instead reports A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. The decisive observation must be: A failing agent trace identifies the specific tool and error without storing sensitive prompt contents.
Regression runs expose failures before deployment and version-to-version quality changes are measurable. Such evidence would validate a different change: An agent team declares production readiness after one demonstration without evaluating factual errors or unauthorized tool calls. It follows the separate remedy Create a representative evaluation dataset with accuracy, tool-use, access-control and refusal tests plus release thresholds. The Timberline Foods scenario instead reports A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. The decisive observation must be: A failing agent trace identifies the specific tool and error without storing sensitive prompt contents.
The agent lists only cases the calling user may view and direct database credentials are not present. Such evidence would validate a different change: A custom Foundry agent must query customer cases through enterprise tools but its developer gives it broad direct database access. It follows the separate remedy Expose narrowly scoped Microsoft Power Platform MCP server tools with authenticated authorization per operation. The Timberline Foods scenario instead reports A Foundry agent intermittently fails during a downstream MCP call but telemetry records only the final response text. The decisive observation must be: A failing agent trace identifies the specific tool and error without storing sensitive prompt contents.
