PL-300 Practice Test
Updated for October 2026What changed for the PL-300 exam in 2026
- Skills outline refreshed April 20, 2026: the current PL-300 study guide (last revised March 2026) lists minor changes to "Get or connect to data", "Enhance reports for usability and storytelling" and "Create and manage workspaces and assets"; the four domains and their weights did not change. (source)
- Domain weights as of April 20, 2026: Prepare the data 25–30%, Model the data 25–30%, Visualize and analyze the data 25–30%, Manage and secure Power BI 15–20%. (source)
- Fabric and Copilot are now on the outline: the 2026 skills list includes choosing between Direct Lake, DirectQuery and Import, connecting to a shared semantic model, DAX query view, visual calculations, and using Copilot to build narrative visuals, create or suggest report pages, and summarize a semantic model. Questions may also cover commonly used Preview features. (source)
- Exam fee is US$165 in the United States (US$106 equivalent in the UK, INR 4,865 in India); Microsoft prices the exam by the country in which it is proctored, and you pay again for each retake. (source) (source)
- Format: 100 minutes of exam time (about 120 minutes seat time) with no labs, scored 1–1,000 with a passing score of 700 (a scaled score, not 70%). Microsoft says most of its certification exams contain 40–60 questions but does not publish a PL-300-specific count. You can open Microsoft Learn inside the exam. (source) (source) (source)
- Delivery: scheduled through Pearson VUE, either at a test center or online with OnVUE proctoring; you can book up to 90 days ahead and hold at most two Microsoft exam appointments at once. Offered in English, Japanese, Chinese (Simplified and Traditional), Korean, German, French, Spanish, Portuguese (Brazil) and Italian. (source) (source)
- Retake policy (page updated July 2026): wait 24 hours after a first fail, then 14 days between later attempts, maximum five attempts in 12 months; you cannot retake an exam you have passed unless the certification has expired. (source)
- Renewal: the Power BI Data Analyst Associate certification is valid for one year; renew free through an unproctored, open-book online assessment (about 45 minutes) on Microsoft Learn during the six months before expiry, with unlimited attempts. A lapsed certification must be re-earned by passing PL-300 again. (source) (source) (source)

PL-300 Key Concepts Flashcards
📊 What are the four PL-300 exam domains and their weights?
Prepare the data (25–30%), Model the data (25–30%), Visualize and analyze the data (25–30%), and Manage and secure Power BI (15–20%). Any PL 300 practice exam you take should cover all four in roughly those proportions.
START PREPARE THE DATA PRACTICE TEST🔧 What does Power Query do in Power BI?
Power Query is the extract-transform-load layer of Power BI. You connect to sources, then clean and shape data with steps such as removing columns, changing data types, unpivoting and merging queries; each step is recorded in the M language.
START POWER QUERY PRACTICE TEST⭐ Why is a star schema the preferred Power BI model?
A star schema puts numeric facts in one fact table and descriptive attributes in dimension tables joined by one-to-many relationships. It keeps DAX simple, filters flow predictably from dimensions to facts, and it performs far better than a single flat table.
START MODEL THE DATA PRACTICE TEST🧮 Measure vs calculated column: which should you use?
A calculated column is computed row by row at refresh and stored in the model, so it uses memory. A measure is evaluated at query time in the current filter context. Use measures for aggregations such as totals and ratios; use calculated columns only when you need the value as a slicer, axis or relationship key.
START DAX PRACTICE TEST🎯 What does CALCULATE do, and how does FILTER fit in?
CALCULATE evaluates an expression under a modified filter context, adding or replacing filters. FILTER returns a table of rows that meet a condition and is often passed to CALCULATE when the filter needs a row-by-row test that a simple column filter cannot express.
START DAX PRACTICE TEST🔗 What is cross-filter direction in a relationship?
Single direction means filters flow only from the "one" side to the "many" side of a relationship. Both directions lets filters flow both ways but can create ambiguity and slow the model, so the exam expects you to keep single direction unless a specific scenario needs bi-directional filtering.
START RELATIONSHIPS PRACTICE TEST🔒 How does row-level security (RLS) work?
RLS restricts which rows a user can see. You define roles in Power BI Desktop with DAX table filters (for example, [Region] = USERPRINCIPALNAME() lookups), publish the semantic model, then assign users or groups to those roles in the Power BI service. Static RLS hard-codes values; dynamic RLS uses the signed-in user.
START RLS PRACTICE TEST☁️ Import, DirectQuery or Direct Lake: how do you choose?
Import copies data into memory for the fastest visuals and full DAX support. DirectQuery leaves data at the source for near-real-time results with larger datasets but slower queries. Direct Lake reads Delta tables from a Fabric lakehouse directly, combining import-like speed with no scheduled refresh.
START DATA CONNECTIVITY PRACTICE TEST🚀 What are workspaces and deployment pipelines for?
A workspace is a container in the Power BI service that holds reports, semantic models, dataflows and apps and controls who can view or edit them. Deployment pipelines promote content through Development, Test and Production stages so you can validate changes before users see them.
START DEPLOY AND MAINTAIN PRACTICE TEST📝 How is the PL-300 exam scored and how long is the certification valid?
PL-300 is scored on a 1–1,000 scale with a passing score of 700 and you get 100 minutes of exam time. The Power BI Data Analyst Associate certification is valid for one year and can be renewed free with an online assessment on Microsoft Learn before it expires.
