If you want your data to automatically refresh as you interact with visualizations, which
option should you choose?
A) Import
B) DirectQuery – B) DirectQuery
Explanation: When you use DirectQuery, no data is imported into Power BI Desktop. As
you create or interact with a visualization, PowerBI Desktop queries the underlying data
source, i.e. you’re always viewing current data.
How do you connect to Excel files that contain target figures? The solution should
involve minimum manual work when new Excel files are created.
A) Connect to the files with Folder connector and use the Combine Binaries
functionality.
B) Connect to a new file each month, perform transformations, and use Append function
in Power Query Editor to combine all targets in the same table. – A) Connect to the
files with Folder connector and use the Combine Binaries functionality.
Explanation: Connecting to files separately will take time if there are lots of files in the
folder. Its always better to connect to folder if files have same structure. If you copy new
files in that folder with same structure, that file will be loaded automatically without doing
any change to data sources.
Imagine that you have created a query named “Customers” in a PowerBI Desktop to
append the rowss from three external tables with customer data into a single output
table named “Customers”.
What would be the best approach to add a new fabricated ID column to the Customers
table to ensure that every row in the “Customers” table contains a unique ID value?
A) Modify the Customer query by adding a counter column.
B) Modify the data model by extending the Customers table with a Counter column.
C) Modify the customers query by adding an index column.
D) Modify the data model by extending the Customers table with an index column. – C)
Modify the Customers query by adding an index column.
1 \/ 3
Explanation: Index column option is available in query editor to add indexed column
starting from 0, 1, or custom number.
Which two of the following strategies are recommended when designing the queries to
import data from an OLTP-style database into a Power BI Desktop project?
A) Normalizing the data model to make it better suited for data analysis and reporting.
B) Denormalizing the data model to make it better suited for data analysis and reporting.
C) Refactoring the imported tables into a multidimensional cube.
D) Refactoring the imported tables into a star schema. – B) Denormalizing the data
model to make it better suited for data analysis and reporting.
D) Refactoring the imported tables into a star schema.
Explanation: Denormalization and star schema is desired to transform the data in the
format that is best fit for visualizations.
Which of the following statements are true with respect to designing a Power BI
Desktop project in DirectQuery mode?
A) All queries within the project must be from a single source database.
B) No support for parent-child DAX functions.
C) You cannot convert column data types when editing a query.
D) You cannot add measures to the data model. – B) No support for parent-child
functions.
Explanation: When in DirectQuery mode, it is not possible to use the family of ‘DAX
PATH( )’ functions that generally handle parent-child structures, such as chart of
accounts, or employee hierarchies.
Which three transformations are available when you right-click a column header in the
Query Editor window?
A) Remove
B) Duplicate Column
C) Change Type
2 \/ 3
D) Count Rows – A) Remove
B) Duplicate Column
C) Change Type
D) Count Rows
Answer: Count Rows option is not there when you right click on column.
When using the “Split Column by Delimiter” transformation, which option may result in
more than two columns?
A) At the left-most delimiter.
B) At each occurrence of the delimiter.
C) At the right-most delimiter.
D) None of the Above. – B) At each occurrence of the delimiter.
Explanation: Using “At each occurrence of the delimiter”, number of columns will
depend on number of times a delimiter is used in string\/text.
Select the feature that allows you to navigate through HTML tags to get the data from
website?
A) Get JSON Data.
B) Web Scraping.
C) Scaffolding. – B) Web Scraping
Explanation: Web Scraping is the new feature of PowerBI that allows you to navigate
through HTML tags to get data from website.
Client provides you with SQL Server Analysis Service database connectivity with
Multidimensional database structure.
To import data use Get Data -> SQL Server Analysis Service and data will be imported
to Power BI.
Is this statement correct?
A) True
B) False – B) False
A dataset is available in PowerBI service online. Would you be able to import data from
Power BI Service using Get Data –> Power BI dataset?<\/p>\n","protected":false},"excerpt":{"rendered":"
