Which column should you remove?

You use the Vertipaq Analyzer to analyze tables in a dataset as shown in the Tables exhibit. (Click the Tables tab.)

The table relationships for the dataset are shown in the Relationships exhibit. (Click the Relationships tab.)

You need to reduce the model size by eliminating invalid relationships.

Which column should you remove?
A . Sales[Sales Amount]
B. Sales[RowlD]
C. Sales[Sales ID]
D. Plan[RowlD]

Answer: B

Explanation:

Sales[Row ID] has 858,786 missing keys and 858,789 Max From Cardinality.

Note: The Max From Cardinality column defines the cost of the relationship which is the amount of time DAX needs to transfer the filters from the dimensions table to the fact table.
