Microsoft Power BI Data Analyst (PL-300) Study Guide [141 Minute Read]

A First-Principles Approach to Business Intelligence with Power BI

Welcome. Most people who fail the PL-300 don't fail because they never opened Power BI; they fail because they learned it as a collection of buttons. This guide builds a mental model instead: why a star schema makes DAX simple, why a filter flows the way it does, why one storage mode suits a scenario and another doesn't. Once you understand the "why," the exam's scenarios stop being memory tests and become problems you can reason through.

Official Exam Objectives: PL-300 Study Guide — Microsoft Learn (skills measured as of April 20, 2026)

The PL-300 is scenario-driven. Most questions describe a business requirement ("You need to ensure that…", "You need to minimize the size of the model…", "Users must see only…") and ask what you should do. Expect multiple-choice and multi-select items, drag-drop sequencing (often Power Query steps or configuration order), hotspot items that ask you to complete a DAX expression or pick settings, and at least one case study. The exam typically has 40–60 questions in 100 minutes, with a passing score of 700 out of 1000. There are no prerequisites. Microsoft offers a free exam sandbox and practice assessment, and the certification renews every 12 months through a free online assessment on Microsoft Learn.

Exam Domain Weights

Three domains carry equal weight, and together they trace the analyst's workflow from raw source to finished report. That is why this guide follows the same order: prepare, model, visualize, then manage and secure. The smallest domain still accounts for roughly 7–12 questions, and its topics (workspace roles, row-level security, gateways) are among the most predictable on the exam, so treat it as points you can bank.
