  • Q1
    Which of the following statements is NOT true about many-to-many relationships in Power BI?
    Many-to-many relationships can lead to ambiguous results in complex data models.
    Many-to-many relationships can be resolved by creating a bridge table.
    Creating a duplicate of an existing table is the only way to resolve a many-to-many relationship.
    Many-to-many relationships are always the best way to connect two tables with a common column.
  • Q2
    How can you identify a many-to-many relationship in Power BI?
    By looking for a common column between two tables.
    By analyzing the data types of the columns in two tables.
    By checking the cardinality of the relationship between two tables.
    By checking the number of rows in each table.
  • Q3
    What is the best practice for resolving a many-to-many relationship in Power BI?
    Create a bridge table with the common column and remove duplicates from the bridge table.
    Change the data type of the common column to create a one-to-one relationship.
    Delete one of the tables involved in the relationship.
    Ignore the relationship and treat the tables as separate entities.
  • Q4
    What are the benefits of using a bridge table to resolve a many-to-many relationship?
    It improves the performance of the Power BI report.
    It allows you to create new calculated columns based on both tables.
    It eliminates ambiguity in the data model and ensures accurate visualizations.
    It reduces the number of tables in the model, making it simpler.
  • Q5
    What should you remember when pulling data from a bridge table in Power BI?
    You should only pull columns from the bridge table that are related to the visualization you are creating.
    You can pull any column from the bridge table or the original tables.
    You cannot pull data from a bridge table directly; you need to use the original tables.
    You should always pull the common column from the original table, not the bridge table.
  • Q6
    What is the downside of creating a bridge table to resolve a many-to-many relationship?
    It is not supported in all versions of Power BI.
    It requires additional calculations to be performed.
    It can increase the complexity of the data model.
    It can lead to data loss if not created correctly.
  • Q7
    Which of the following is an alternative approach to resolving a many-to-many relationship, besides using a bridge table?
    Creating a calculated column that combines the relevant data from both tables.
    Merging the two tables into a single table.
    Using a third table to act as an intermediary between the two original tables.
    Defining a hierarchy in one of the tables to represent the many-to-many relationship.
  • Q8
    In the context of Power BI interviews, what is more important than simply knowing how to resolve a many-to-many relationship?
    Being able to explain the concept clearly and demonstrate the steps involved.
    Being able to code complex DAX formulas.
    Having a deep understanding of the underlying data model.
    Memorizing the answer that creating a bridge table is the solution.
  • Q9
    What does the presence of a cardinality warning in Power BI signify?
    It suggests that the relationship between two tables may not be optimal.
    It means that the data types of two columns are incompatible.
    It highlights a performance issue with the model.
    It indicates that a potential error exists in the data model.
  • Q10
    How can you avoid ambiguity in your Power BI reports when dealing with many-to-many relationships?
    By properly resolving many-to-many relationships in your data model.
    By using clear and concise labels for your columns and tables.
    By ensuring that all your data sources are consistent.
    By implementing data governance practices within your organization.
