Question 70
A Fabric administrator receives the following requirement: A semantic model stores transaction GUIDs in multiple high-cardinality string columns that reports never use. What should the engineer do?
Explanation
Correct Answer
Wide high-cardinality data can consume memory without adding analytical value. The recommended action directly addresses the stated requirement.
Incorrect Answers
This action is appropriate when a model creates hundreds of calculated columns for values that can be computed in source SQL. Model size and refresh work may fall when unnecessary calculated columns are removed. However, the question instead requires Remove unneeded high-cardinality columns from the model. because wide high-cardinality data can consume memory without adding analytical value.
This action is appropriate when a model uses bidirectional filters on every relationship and reports contain ambiguous results. Relationship design affects both query work and analytical correctness. However, the question instead requires Remove unneeded high-cardinality columns from the model. because wide high-cardinality data can consume memory without adding analytical value.
This action is appropriate when a fact table includes a verbose description repeated across millions of rows. Dimensional normalization can reduce repeated text and improve compression. However, the question instead requires Remove unneeded high-cardinality columns from the model. because wide high-cardinality data can consume memory without adding analytical value.
