Microsoft Power BI Data Analyst (PL-300 Korean Version) Sample Questions:
Power BI를 사용하여 재무 보고서를 작성하고 있습니다.
financials라는 테이블이 있고, 그 테이블에는 Date라는 열과 Sales라는 열이 있습니다.
전 분기 대비 매출의 상대적 변화를 계산하는 측정값을 만들어야 합니다.
이 설문 조사를 어떻게 완료해야 할까요? 답변하려면 답변란에서 적절한 옵션을 선택하세요.
참고: 정답 하나당 1점입니다.
Correct Answer:
Explanation:
The verified mapping records 1) CALCULATE; 2) DATEADD; 3) DIVIDE. The scenario is asking for a way to create a measure that calculates the relative change in sales as compared to the previous quarter. A text month or an incomplete date column cannot supply a reliable chronological hierarchy or the contiguous dates expected by time-intelligence calculations. A dedicated, contiguous date table supports month, quarter, and year analysis consistently. Marking it as a date table tells Power BI which column represents the model ' s canonical dates. In Microsoft ' s current exam outline, the corresponding objective is " Create a common date table " . It also preserves predictable filter context and aggregation behavior when the result is used by several visuals or report pages.

Correct Answer:
Explanation:
Power Query should resolve this requirement before the data enters the semantic model. The chosen transformation preserves the required rows and grain while converting the source layout into an analysis- ready table. Use the selections preserved in the answer exhibit as the supported configuration. The technical decision turns on how to import attributes as columns from all the documents in the JSON file. A visual, measure, or model relationship cannot repair the incoming tabular shape; those features operate after the query result has already been loaded. This rationale is anchored to the PL-300 objective " Convert semi- structured data to a table " . This keeps the query output reproducible at refresh and leaves the semantic model with the grain and schema required by the report.

Power BI 시맨틱 모델에 Item이라는 테이블이 있습니다. Item 테이블에는 Quantity라는 열이 있습니다. 다음 요구 사항을 충족하는 DAX 쿼리를 작성해야 합니다.
품목의 순위는 수량 값에 따라 계산해야 합니다.
수량 값이 같은 항목이 두 개 이상 있는 경우 순위 매기기를 건너뛰어서는 안 됩니다.
필터링되지 않은 항목의 경우, 수량의 총합은 공백으로 표시되어야 합니다.
DAX 수식을 어떻게 완성해야 합니까? 답하려면 답변 영역에서 적절한 옵션을 선택하십시오.
참고: 정답 하나당 1점입니다.
Correct Answer:
Explanation:
The retained answer-area mapping contains the correct selections. The scenario is asking for a way to create a DAX query that meets the following requirements:; The rank of items must be calculated according to the values in Quantity.; Ranking must NOT be skipped if two. Guessing from total page time does not isolate the slow visual or measure; the diagnostic must separate DAX query, visual display, and other processing duration. Performance Analyzer records how long each visual spends on its DAX query, display, and other processing. DAX query view can then run and inspect a copied query to isolate the measure responsible for slow execution. In Microsoft ' s current exam outline, the corresponding objective is " Identify poorly performing measures, relationships, and visuals by using Performance Analyzer and DAX query view " .
