Selected Answer: A
A: Sí, porque al crear el campo calculado en el dataset se precomputan los valores y se materializan en SPICE, asegurando precisión y rapidez. B: No, porque los campos calculados en el análisis se calculan en tiempo de consulta, no se precomputan. C: No, porque los campos calculados en la visual se generan al renderizar, no se almacenan en SPICE. D: No, porque los campos calculados en el dashboard tampoco se precomputan en SPICE.
