You have a Microsoft Power Bl semantic model that contains measures. The measures use multiple calculate functions and a filter function.

You are evaluating the performance of the measures.

In which use case will replacing the filter function with the keepfilters function reduce execution time?

A.
when the filter function uses a nested calculate function
Answers
A.
when the filter function uses a nested calculate function
B.
when the filter function references a column from a single table that uses Import mode
Answers
B.
when the filter function references a column from a single table that uses Import mode
C.
when the filter function references columns from multiple tables
Answers
C.
when the filter function references columns from multiple tables
D.
when the filter function references a measure
Answers
D.
when the filter function references a measure
Suggested answer: A

Explanation:

The KEEPFILTERS function modifies the way filters are applied in calculations done through the CALCULATE function. It can be particularly beneficial to replace the FILTER function with KEEPFILTERS when the filter context is being overridden by nested CALCULATE functions, which may remove filters that are being applied on a column. This can potentially reduce execution time because KEEPFILTERS maintains the existing filter context and allows the nested CALCULATE functions to be evaluated more efficiently.
