Topic: data preparation
A sales dataset has inconsistent region names and missing values. What should the analyst do first?
Best answer: A
Explanation: PL-300 emphasizes preparing and transforming data before analysis. Poor data quality weakens every report.
What this tests: Preparing data for analysis.
Topic: data model
A report has slow visuals because every measure scans a wide flat table. What should be reviewed?
Best answer: B
Explanation: Power BI performance and usability depend heavily on model structure.
What this tests: Designing efficient semantic models.
Topic: DAX
A measure must calculate year-to-date sales based on the report date context. What skill is most relevant?
Best answer: C
Explanation: DAX measures evaluate in filter context. Time intelligence is a common PL-300 concept.
What this tests: Applying DAX and filter context.
Topic: relationships
A visual double-counts sales after a table join. What should be inspected?
Best answer: D
Explanation: Incorrect relationships or grain can produce misleading totals. Analysts must validate model behavior.
What this tests: Troubleshooting model relationships.
Topic: visualization
Executives need quick comparison of profit by product category and region. What should guide visual choice?
Best answer: A
Explanation: PL-300 rewards clear data storytelling and appropriate visual selection.
What this tests: Choosing effective visuals.
Topic: row-level security
Regional managers should see only their own region’s data. What should be implemented?
Best answer: B
Explanation: RLS enforces data access at model level when properly designed and tested.
What this tests: Implementing report security.
Topic: refresh
A report shows stale data after source updates. What should be checked?
Best answer: C
Explanation: Refresh issues often involve schedule, credentials, gateway, source errors, or capacity constraints.
What this tests: Troubleshooting refresh problems.
Topic: Power Query
A source column needs splitting and standardization before load. Where is this usually handled?
Best answer: D
Explanation: Power Query is used for extract, transform, and load steps before modeling.
What this tests: Using Power Query for transformation.
Topic: workspace governance
A report must be reviewed before business users see it. What should be planned?
Best answer: A
Explanation: Power BI governance includes workspace roles and controlled publication.
What this tests: Managing report lifecycle and governance.
Topic: performance analyzer
Users complain one report page is slow. What should the analyst use?
Best answer: B
Explanation: Performance analysis should identify whether visuals, DAX, model design, or source queries are causing delays.
What this tests: Optimizing report performance.
Topic: business metric
A revenue measure is defined differently by sales and finance. What should the analyst do?
Best answer: C
Explanation: Trusted analytics depend on agreed definitions and governance.
What this tests: Managing metric definitions.
Topic: route fit
A candidate prepares data, builds semantic models, writes DAX, and publishes Power BI reports. Which route is closest?
Best answer: D
Explanation: PL-300 is the Microsoft Power BI Data Analyst route.
What this tests: Choosing the Power BI data analyst route.

| Cue | What to remember |
|---|---|
| Data prep | Clean, shape, and combine data before modeling. |
| Modeling | Design relationships, star schema patterns, measures, and hierarchies for accurate analysis. |
| DAX | Use measures and filter context carefully rather than forcing logic into visuals. |
| Visualization | Choose visuals that answer the business question clearly and accessibly. |
| Deployment | Plan workspaces, refresh, row-level security, sharing, and adoption. |
