- Correct answer : A — Time travel is unsupported on tables with row filters or column masks attached, so this `VERSION AS OF` query is expected to fail outright A . Unity Catalog documents time travel as one of the operations unsupported on tables with row filters or column masks attached, so a `VERSION AS OF` query against such a table is expected to be rejected rather than succeed. B . Because time travel itself is unsupported once these policies are present, the engineer cannot retrieve the historical version at all, regardless of whether the older data predates the policy's creation. C . The restriction causes the query to fail rather than quietly substitute the current table state for the requested historical version, so no result set is silently returned. D . The unsupported-operation restriction is not bypassed by admin group membership; row filter and column mask logic controls row and column visibility, but the time-travel limitation applies at the table level regardless of who is querying.
