You need to create a calculated column to show the date in a format like this February 01, 2021. Which of the following DAX expressions would you use?
A. FORMAT([Date],”M”)|| FORMAT([Date],”D”)|| FORMAT([Date],”Y”)

You are interested in creating a measure that will always calculate the total sales for 2020, irrespective of the year selected in any other visual in Power BI. Which of the following is the right way to create such a measure?
A. Total Sales for 2020= CALCULATE(SUM(‘Sales OrderDetails’[Total Price]), YEAR(‘Sales OrderDetails’[orderdate]) = 2020)
B. Total Sales for 2020= SUM(CALCULATE(‘Sales OrderDetails’[Total Price]), YEAR(‘Sales OrderDetails’[orderdate]) = 2020)
C. Total Sales for 2020= TOTAL(SUM(‘Sales OrderDetails’[Total Price]), YEAR(‘Sales OrderDetails’[orderdate]) = 2020)
D. It is not possible to create such a measure.
A. Total Sales for 2020= CALCULATE(SUM(‘Sales OrderDetails’[Total Price]), YEAR(‘Sales OrderDetails’[orderdate]) = 2020)
The CALCULATE function in DAX helps in creating a measure that will override the specific portions of the context that are being utilized to express the correct result. The syntax to use the calculate function is:
CALCULATE(<expression>[, <filter1> [, <filter2> [, …]]])
Where expression represents the expression that is to be evaluated and Filter1, Filter2 are optional and represent the table or Boolean expressions that define filters, or filter modifier functions.</filter2></filter1></expression>
What will be the result of the following DAX formula if the year 2020 is chosen on a slicer of a report?
2019 Salary_Cost = CALCULATE([Total Salary_cost], Filter (Date, Date[Year]=2019))
A. Salary_cost for the Year 2020 as Slicer Selection overrides DAX Filter.
B. Salary_cost for the Year 2019 as DAX Filter overrides Slicer Selection.
C. Blank. It will return no records.
D. It will return Salary_cost records for the year 2019 as well as 2020.
C. Blank. It will return no records.
First, the given DAX expression was supposed to have a SUM function to calculate the total sales. Moreover, in the given scenario, the Slicer selection for the year 2020 will also be applied along with the DAX expression. It is not possible for any record to have both years i.e year 2019 and year 2020 at the same time. Therefore, the given DAX expression in the current scenario will return nothing.
Which of the following is the right DAX function to modify a single directional relationship to a bi-directional relationship on the fly (within the measure)?
A. TREATAS
B. USERELATIONSHIP
C. CROSSFILTER
D. RELATEDTABLE
E. RELATED

C. Restricting data access for the given users ( By assigning users to roles)
D. Restrictions to specific measures within Power BI reports to some specific users
E. All the above
C. Restricting data access for the given users ( By assigning users to roles)
The use of Row Level Security in Power BI is to restrict or limit the data access for the specified users. The Filters restrict the data access at row-level and filters can be defined within roles. In Power BI service, the members can access the datasets in the workspace. Row Level security does not put restrictions on this data access.
Consider that you want to split your query into two parts. Which of the following options would you use in Power BI?
A. Format Query
B. Split Query
C. Extract previous
D. Mark Query
C. Extract previous
Extract Previous is the option that helps in splitting the query into parts. If you want to split a query, right-click an applied step (as per desire or requirements) to the query and choose the exact previous option. It will split the query into 2 parts by making a new query consisting of all the steps before the selected step.
Consider the statement below.
Row Level Security can’t be applied in Power BI Desktop while connecting via a Live connection to Analysis Services, these need to be set within the AS model.
A. True
B. False
B. False
You can configure Row-Level Security for the data models imported in Power BI through Power BI Desktop. It is also possible to configure Row Level Security (RLS) on the datasets that use DirectQuery, such as SQL Server. But for Analysis Services or Azure Analysis Services live connections, Row-level security is configured within the model, not Power BI Desktop. The AS models hold RLS roles already that can be used by Power BI via a Live connection.
