Explanation:
Explanation:
Use Power Query to calculate calendar quarter and calendar month.
Scenario:
A single dataset must support all three reports:
- The Top Customers report will show the top 20 customers based on the highest sales amounts in a selected order month or quarter, product category, and sales region.
- The Top Products report will show the top 20 products based on the highest sales amounts sold in a selected order month or quarter, sales region, and product category.
The data model must minimize the size of the dataset as much as possible, while meeting the report requirements and the technical requirements.
Question 9
You need to create the On-Time Shipping report. The report must include a visualization that shows the percentage of late orders.
Which type of visualization should you create?
Options:
A.
bar chart
B.
scatterplot
C.
pie chart
Answer:
A
Explanation:
Explanation:
Scenario: The On-Time Shipping report will show the following metrics for a selected shipping month or quarter:
The percentage of orders that were shipped late by country and shipping region
Customers that had multiple late shipments during the last quarter
Note: Bar and column charts are some of the most widely used visualization charts in Power BI. They can be used for one or multiple categories. Both these chart types represent data with rectangular bars, where the size of the bar is proportional to the magnitude of data values.
The difference between the two is that if the rectangles are stacked horizontally, it is called a bar chart. If the rectangles are vertically aligned, it is called a column chart.

Explanation:
Scenario: Revenue projections are set at the monthly level and summed to show projections for the quarter.
Box 1: IF
Box 2: ISFILTERED
ISFILTERED returns TRUE when columnName is being filtered directly. If there is no filter on the column or if the filtering happens because a different column in the same table or in a related table is being filtered then the function returns FALSE.
Which DAX expression should you use to get the ending balances in the balance sheet reports?
Options:
A.
CALCULATE (
SUM( BalanceSheet [BalanceAmount] ),
DATESQTD( 'Date'[Date] )
)
B.
CALCULATE (
SUM( BalanceSheet [BalanceAmount] ),
LASTDATE( 'Date'[Date] )
)
C.
FIRSTNONBLANK ( 'Date' [Date]
SUM( BalanceSheet[BalanceAmount] )
)
D.
CALCULATE (
MAX( BalanceSheet[BalanceAmount] ),
LASTDATE( 'Date' [Date] )
)
Answer:
A
Explanation:
Explanation:
Scenario: At least one of the balance sheet reports in the quarterly reporting package must show the ending balances for the quarter, as well as for the previous quarter.
DATESQTD returns a table that contains a column of the dates for the quarter to date, in the current context.
What is the minimum number of datasets and storage modes required to support the reports?
Options:
A.
two imported datasets
B.
a single DirectQuery dataset
C.
two DirectQuery datasets
D.
a single imported dataset
Answer:
D
Explanation:
Explanation:
"The analysts responsible for each business unit must see all the data the board sees, except the profit and loss data, which must be restricted to only their business unit's data. The analysts must be able to build new reports from the dataset that contains the profit and loss data" => one dataset and two separate workspaces Reason: All data can be imported into one dataset also if these are two logical models. Shared dimensions can be reconsumed in both models. Reports and additional materials can be shared to the board with an app. The "profit and loss" data model needs RLS for the analysts and the analysts must have just read access to the original workspace. In a separate workspace with contributer (or more rights) they can create new reports (with live connection to the dataset). It is also stated that the new reports mustn't be shared so therefore no need to include them into the app. Import vs. DirectQuery: Due to RLS requirements an imported dataset is needed. It is not possible with file sources and Sharepoint lists.
Question 20
You need to recommend a strategy to consistently define the business unit, department, and product category data and make the data usable across reports.
What should you recommend?
Options:
A.
Create a shared dataset for each standardized entity.
B.
Create dataflows for the standardized data and make the dataflows available for use in all imported datasets.
C.
For every report, create and use a single shared dataset that contains the standardized data.
D.
For the three entities, create exports of the data from the Power Bl model to Excel and store the data in Microsoft OneDrive for others to use as a source.
Answer:
B
Question 21
Which two types of visualizations can be used in the balance sheet reports to meet the reporting goals? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Options:
A.
a line chart that shows balances by quarter filtered to account categories that are long-term liabilities.
B.
a clustered column chart that shows balances by date (x-axis) and account category (legend) without
filters.
C.
a clustered column chart that shows balances by quarter filtered to account categories that are long-term liabilities.
D.
a pie chart that shows balances by account category without filters.
E.
a ribbon chart that shows balances by quarter and accounts in the legend.
You have a CSV file that contains user complaints. The file contains a column named Logged. Logged contains the date and time each complaint occurred. The data in Logged is in the following format: 2018-12-31 at 08:59.
You need to be able to analyze the complaints by the logged date and use a built-in date hierarchy.
What should you do?
Options:
A.
Apply a transformation to extract the last 11 characters of the Logged column and set the data type of the new column to Date.
B.
Change the data type of the Logged column to Date.
C.
Split the Logged column by using at as the delimiter.
D.
Apply a transformation to extract the first 11 characters of the Logged column.
Answer:
C
Explanation:
Explanation:
Simply create a custom table in Power Query, enter the date shown in the question into a column called Date, and then Split it by a delimiter. No need for spaces on either side of "at" Power BI takes care of the rest:
It will even automatically change the type to Date:
= Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Date.1", type date}, {"Date.2", type time}})
Question 24
You are building a Power BI report to analyze customer segments.
You need to identify customer segments dynamically based on the Bounce Rate across dimensions such as source, geography, and demographics. The solution must minimize analysis effort.
Which type of visualization should you use?
Options:
A.
decomposition tree
B.
funnel chart
C.
Q&A
D.
key influencers
Answer:
A
Explanation:
Explanation:
The key influencers visual is a great choice if you want to:
See which factors affect the metric being analyzed.
Contrast the relative importance of these factors. For example, do short-term contracts affect churn more than long-term contracts?
Note: The key influencers visual helps you understand the factors that drive a metric you're interested in. It analyzes your data, ranks the factors that matter, and displays them as key influencers. For example, suppose you want to figure out what influences employee turnover, which is also known as churn. One factor might be employment contract length, and another factor might be commute time.
You have a report that contains three pages. One of the pages contains a KPI visualization. You need to filter all the visualizations in the report except for the KPI visualization. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Options:
A.
Add the same slicer to each page and configure Sync slicers.
B.
Edit the interactions of the KPI visualization.
C.
Configure a page-level filter.
D.
Edit the interactions of the slicer that is on the same page as the KPI visualization.
E.
Configure a report-level filter.
Answer:
A, D
Explanation:
Explanation:
Slicers are another way of filtering. They narrow the portion of the dataset that is shown in the other report visualizations.
By default, slicers on report pages affect all the other visualizations on that page, including each other. Use visual interactions to exclude some page visualizations from being affected by others.
You merge data from Sales.Region, Region_Manager, Sales_Manager, and Manager into a single table named Region. What should you do next to meet the reporting requirements of the executives?
