問題文
During the quarterly close, a controller asks whether Copilot could be used to cross-check figures across departments to spot inconsistencies. What is the key constraint on this idea?
選択肢
- Cross-department checks are blocked by data protection policies by default, since comparing one department's figures with another's is exactly the kind of movement of information those policies exist to prevent.
- Copilot cannot compare figures across different documents, since each response is grounded in one source at a time and a cross-check by definition needs two side by side.
- Cross-department checks require a separate license tier, since reaching content outside the user's own department is a broader capability than the standard entitlement covers.
- The controller can only cross-check across departments whose figures they have permission to access, so the scope of the check is bounded by their own access.
