Which two statements are true of grouping sets when using smart measures?

The correct answer is A. It is a set of dimensions that generates a result for a measure. D. The generated SQL includes grouping sets for all the aggregations of that measure that are. Grouping sets in smart measures are dimension-based sets that drive measure aggregation, and the generated SQL reflects all relevant measure-level aggregations using GROUPING SETS clauses.

Why each option

Grouping sets in smart measures are dimension-based sets that drive measure aggregation, and the generated SQL reflects all relevant measure-level aggregations using GROUPING SETS clauses.

AIt is a set of dimensions that generates a result for a measure.Correct

A grouping set is defined as a set of dimensions that determines how the database groups data to produce a result for a measure, making dimensions the foundational element of the grouping set construct.

BIt is a set of measures that generates a result for a dimension.

A grouping set is composed of dimensions, not measures - it is not a set of measures used to generate a dimensional result, which inverts the correct relationship.

CThe generated SQL includes grouping sets for all the aggregations of that dimension that are

The generated SQL includes GROUPING SETS for the aggregations of the measure, not for all aggregations of a dimension, since the grouping set mechanism groups dimension combinations to compute measure values.

DThe generated SQL includes grouping sets for all the aggregations of that measure that areCorrect

The SQL generated for smart measures includes GROUPING SETS clauses covering all aggregation levels of the relevant measure, allowing the database to compute multiple aggregations for that measure within a single query.
