1500 Questions | Data Practitioner Certification 2026

Detailed Exam Domain CoverageThe Associate Data Practitioner Certification is designed to test your foundational and intermediate knowledge of the data lifecycle. This practice test bank covers every corner of the official syllabus:Data Modelling and Data Visualisation (31%): Mastering model structures, relationships, and the art of report layout.Data Preparation and Manipulation (27%): Connecting to various sources, filtering, sorting, and summarizing complex datasets.Data Analysis and Modelling (19%): Applying DAX calculations, analysis functions, and industry-standard modelling practices.Data Storytelling and Insights (23%): Translating raw data into actionable recommendations and compelling visual narratives.Preparing for the Associate Data Practitioner Certification requires more than just reading theory; it requires the ability to apply Power BI and data analysis concepts to real-world scenarios, I have developed this comprehensive question bank to bridge the gap between study materials and the actual testing environment, With 1,500 unique practice questions, I provide a rigorous simulation that ensures you are not caught off guard on exam day,Every question is paired with a thorough explanation that breaks down why a specific answer is correct and why the alternatives do not fit, This approach transforms a simple practice test into a powerful learning tool, allowing you to identify knowledge gaps and master the logic behind data transformation, DAX calculations, and storytelling techniques, My goal is to provide the most exhaustive resource available to help you earn your certification with confidence,Sample Practice Questions PreviewQuestion 1: You are working in Power BI Desktop and need to create a relationship between two tables, Sales and Products, Both tables contain a 'ProductID' column, which type of relationship is most appropriate if every sale must be linked to exactly one product, but a product can appear in many sales?A) One-to-one (1:1)B) One-to-many (1:*)C) Many-to-one (*:1)D) Many-to-many (:)E) Single DirectionalF) Bi-directionalCorrect Answer: BExplanation:B (Correct): A One-to-many relationship is the standard for a dimension table (Products) linking to a fact table (Sales) where one product can have multiple sales records,A (Incorrect): One-to-one would imply each product is only ever sold once, which is not typical for sales data,C (Incorrect): While logically similar, the direction from Products to Sales is defined as One-to-many,D (Incorrect): Many-to-many creates complexity and ambiguity that should be avoided in basic star schemas if a unique key exists,E (Incorrect): This refers to cross-filter direction, not the cardinality of the relationship,F (Incorrect): Bi-directional filtering is a property of the relationship, not the relationship type itself,Question 2: While performing data preparation in Power Query, you notice that a 'Region' column has inconsistent casing (e.g., 'north', 'North', 'NORTH'), which transformation step is most efficient to ensure all values are identical for grouping?A) Replace ValuesB) Capitalize Each WordC) Split Column by DelimiterD) Format -> UppercaseE) Group ByF) Remove DuplicatesCorrect Answer: DExplanation:D (Correct): Formatting the entire column to Uppercase (or Lowercase) is the fastest way to standardize text for accurate grouping and analysis,A (Incorrect): Replace Values would require multiple manual entries for every variation of the word,B (Incorrect): While it works, Uppercase is often safer for data keys to avoid trailing space issues or specific regional casing rules,C (Incorrect): Splitting by delimiter does not address the casing of the text within the column,E (Incorrect): Grouping before standardizing would result in separate rows for 'north' and 'North',F (Incorrect): This would delete data rows rather than fixing the formatting of existing data,Question 3: You need to calculate the total sales for the previous year using DAX, which function is specifically designed to shift a set of dates back by exactly one year?A) SUM()B) CALCULATE()C) SAMEPERIODLASTYEAR()D) FILTER()E) ALL()F) RELATED()Correct Answer: CExplanation:C (Correct): SAMEPERIODLASTYEAR is a time-intelligence function that returns a set of dates shifted one year back from the current filter context,A (Incorrect): SUM only aggregates values and cannot handle date shifting on its own,B (Incorrect): CALCULATE is the engine used, but it requires a function like SAMEPERIODLASTYEAR to perform the specific time shift,D (Incorrect): FILTER returns a table based on a condition but does not inherently understand "one year ago" without complex logic,E (Incorrect): ALL removes filters; it does not shift them to a previous period,F (Incorrect): RELATED is used to fetch values from another table in a relationship, not for time calculations,Welcome to the Mock Exams Practice Tests Academy to help you prepare for your Associate Data Practitioner Certification,You can retake the exams as many times as you wantThis is a huge original question bankYou get support from instructors if you have questionsEach question has a detailed explanationMobile-compatible with the Udemy appI hope that by now you're convinced!
