Sums up values in a column Filters a table based on a condition Retrieves a value related to the current row from another table Creates a calculated column 7 / 20 7) Which feature allows you to analyze year-to-date values in Power BI? Conditional formatting Quick measures Data modeling AI visuals 8 / 20 8) What is the main purpose of conditional formatting in Power BI? To secure data To apply filters To dynamically change visual appearance based on data To merge queries 9 / 20 9) Which of the following is NOT an AI visual in Power BI? Key influencer visual Clustering using scatter chart Data bar visual Q&A visual 10 / 20 10) What is the primary purpose of the Performance Analyzer in Power BI? Establishing roles for row-level security Testing scenarios in Power BI service Understanding and enhancing the performance of report elements Analyzing data model relationships 11 / 20 11) On what basis is dynamic row-level security (RLS) created? User roles within an organization Only static data Visual-level filters Direct query mode 12 / 20 12) Workspace apps in Power BI are intended for: Performance tuning Collaboration and report sharing Data transformation DAX calculations 13 / 20 13) When working with parameters and functions, what is the primary use of parameters? To secure data To dynamically change queries based on user input To create calculated columns To create static reports 14 / 20 14) What does setting a similarity threshold affect in fuzzy matching? The speed of data refresh The precision of match results The size of the data model The color scheme of visualizations 15 / 20 15) How does the CALCULATE() function in DAX modify filter context? By merging tables By changing visualization types By applying new filters to existing ones By creating new columns 16 / 20 16) What advantage does the SUMX() function provide over the SUM() function in DAX? Summing across multiple tables Calculating the sum for each row in a table and then aggregating those values Summing only unique values Faster calculation of sums 17 / 20 17) Which of the following is a use case for data profiling in Power BI? To customize the theme of a report To understand data distribution, data quality, and data profile To create new visualizations To set up row-level security 18 / 20 18) What capability does creating a calculated table in Power BI provide? Enhance query performance Dynamically add new data to the model Secure the data model Enable the creation of a new visualization type 19 / 20 19) When building a calendar table in Power BI, what is its primary purpose? To enhance data security To manage user permissions To provide date fields for time intelligence calculations To create custom visuals 20 / 20 20) What is the significance of using the USERELATIONSHIP() function in DAX? It allows the creation of new relationships in the data model It activates an inactive relationship for a specific calculation It changes the direction of a relationship It creates a new table based on relationship criteria Your score is The average score is 99% LinkedIn 0% Restart quiz Exit
