Correct Answer:

Explanation:

Read the completed answer mapping as 1) Total Sales; 2) Occupation; 3) City. The scenario is asking for a way to create a key influencers visualization as shown in the exhibit. Visual selection follows the analytical question: line charts show change over time, bars compare categories, scatter charts expose relationships and outliers, KPIs track progress against a target, and AI visuals explain likely drivers. This directly matches the current study-guide objective " Use AI visuals " . The other visual or configuration choices encode a different task, lose the required interaction, or fail one of the stated display constraints. The result remains understandable to report consumers and responds correctly to the interaction or filtering behavior described in the question.

Correct Answer:

Explanation:

Import-model reduction should remove unused data, lower avoidable cardinality, or aggregate only to the required analytical grain. The selected change preserves every field, row, and precision requirement stated in the question. Use the selections preserved in the answer exhibit as the supported configuration. The relevant context is that you have a power bi report named orders that supports the following analysis:; total sales over time; the count of orders over time; new and repeat customer counts the data model. A proposed optimization is invalid if it drops required columns, removes needed transaction detail, or lowers numeric precision contrary to the scenario. This rationale is anchored to the PL-300 objective " Improve performance by identifying and removing unnecessary rows and columns " .

Correct Answer:

Explanation:

The retained answer-area mapping contains the correct selections. The key constraint is to interpret the Column statistics and Value distribution shown for Column1. A transformation that replaces, removes, or filters values would change the data before the analyst has quantified the problem; profiling is the diagnostic step. Column profile and column distribution expose value frequency, distinct and unique counts, errors, empty values, and statistics for the selected field. Those diagnostics answer a data-quality question without changing the source values. In Microsoft ' s current exam outline, the corresponding objective is " Evaluate data, including data statistics and column properties " . This keeps the query output reproducible at refresh and leaves the semantic model with the grain and schema required by the report.
