PL-300 Key Concepts Flashcards

๐Ÿ“Š What are the four PL-300 exam domains and their weights?

Prepare the data (25โ€“30%), Model the data (25โ€“30%), Visualize and analyze the data (25โ€“30%), and Manage and secure Power BI (15โ€“20%). Any PL 300 practice exam you take should cover all four in roughly those proportions.

START PREPARE THE DATA PRACTICE TEST

๐Ÿ”ง 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

โญ 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

๐Ÿงฎ 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

๐ŸŽฏ 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

๐Ÿ”— 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

๐Ÿ”’ 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

โ˜๏ธ 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

๐Ÿš€ 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

๐Ÿ“ How is the PL-300 exam scored and how long is the certification valid?

PL-300 is scored on a 1โ€“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.

What PL-300 Exam Questions Look Like

The PL 300 exam is a proctored, 100-minute Microsoft associate exam with no labs, and it is scored on a 1–1,000 scale where 700 is the passing score. Microsoft does not publish a PL-300-specific question count; it says most of its certification exams contain 40–60 questions.

PL-300 exam questions are not all classic multiple choice. Microsoft's exam experience page lists the item formats you can meet on its role-based exams: multiple choice, drag and drop (matching items to targets), build list (putting steps in the right order), hot area (clicking the right setting in a screenshot), active screen, and case studies. A case study gives you a scenario with business requirements and an existing environment, followed by several questions that all depend on it. Some items come in problem-and-solution sets where you decide whether a proposed solution meets the goal; you cannot take a break inside those sets.

Two exam-day details matter for pacing. Once you start a break, you cannot return to questions you saw before it, even ones marked for review. And on associate exams such as PL-300 you can open Microsoft Learn inside the exam, which helps you check a DAX function or setting name but takes time away from the clock. Practise with timed PL300 exam questions so you can answer most items without looking anything up.
