What the questions cover
PL-300's skill areas are preparing the data, modelling the data, visualising and analysing the data, and managing and securing Power BI. The 25 questions include append versus merge, unpivoting, column quality, star schemas, relationship direction, CALCULATE, SUMX, RELATED, REMOVEFILTERS, time intelligence, DIVIDE, storage modes, drill-through, row-level security, gateways, dashboards and apps, workspace roles and Performance Analyzer. The exam is scored from 1 to 1,000, with 700 to pass.
A sample question explained
"You need a measure for total sales where each row is Quantity × Price." The answer is SUMX(Sales, Sales[Quantity] * Sales[Price]). SUM accepts only a single column, so it can't multiply two columns row by row. SUMX iterates the table, evaluates the expression for each row, then adds the results. Recognising when you need an iterator (the X functions) is one of the most tested DAX skills.
If you score 17 out of 25 (68%), revise the questions you missed in the review table, then retake with a new set.
Getting the most from it
- Rebuild the questions you miss in Power BI Desktop with a sample dataset.
- Be sure about filter context and context transition; many DAX questions hinge on them.
- The real exam may include case studies; practise reading a long scenario before answering.
