Question 1

You have a Power BI report named ReportA.
You have a Power BI tenant that allows users to export data.
You need to ensure that consumers of ReportA cannot export any data from visuals.
Which two actions should you perform? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A. From Power BI Desktop, modify the Report settings.

B. From Power BI Desktop, modify the Data Load settings.

C. From the Power BI service, modify the dataset permissions.

D. From the Power BI service, modify the Report settings.

 


Suggested Answer: AD

 

Question 2

You have a Power BI workspace named Workspace1 that contains a dataset named DS1 and a report named RPT1.
A user wants to create a report by using the data in DS1 and publish the report to another workspace.
You need to provide the user with the appropriate access. The solution must minimize the number of access permissions granted to the user.
What should you do?

A. Add the user as a Viewer of Workspace1.

B. Grant the Build permission for DS1 to the user.

C. Share RPT1 with the user.

D. Add the user as a member of Workspace1.

 


Suggested Answer: B

More granular permissions –
Power BI provides the Build permission as a complement to the existing permissions, Read and Reshare. All users who already had Read permission for datasets via app permissions, sharing, or workspace access at that time also got Build permission for those same datasets. They got Build permission automatically because Read permission already granted them the right to build new content on top of the dataset, by using Analyze in Excel or Export.
With this more granular Build permission, you can choose who can only view the content in the existing report or dashboard and who can create content connected to the underlying datasets.
If your dataset is being used by a report outside the dataset workspace, you can’t delete that dataset. Instead, you see an error message.
Reference:
https://docs.microsoft.com/en-us/power-bi/connect-data/service-datasets-build-permissions

Question 3

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?

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.

 


Suggested Answer: D

Extract the date, which is the first 11 characters.
CSV files have no data types.
Note: A CSV is a comma-separated values file, which allows data to be saved in a tabular format. CSVs look like a garden-variety spreadsheet but with a . csv extension. CSV files can be used with most any spreadsheet program, such as Microsoft Excel or Google Spreadsheets.

Question 4

You have four sales regions. Each region has multiple sales managers.
You implement row-level security (RLS) in a data model. You assign the relevant mail-enabled security group to each role.
You have sales reports that enable analysis by region. The sales managers can view the sales records of their region. The sales managers are prevented from viewing records from other regions.
A sales manager changes to a different region.
You need to ensure that the sales manager can see the correct sales data.
What should you do?

A. Change the Microsoft Power BI license type of the sales manager.

B. From Microsoft Power BI Desktop, edit the Row-Level Security setting for the reports.

C. Manage the permissions of the underlying dataset.

D. Request that the sales manager be added to the correct Azure Active Directory group.

 


Suggested Answer: D

You can use the following groups to set up row level security.
* Distribution Group
* Mail-enabled Group – This group also contains a list of email addresses of members and can also be used to control access to OneDrive and SharePoint.
The Mail-Enabled Security Group can be created in the Office 365 Admin Portal.
* Security Group – This is also known as an Active Directory Security Group. This group lives within Active Directory and Azure Active Directory.

Question 5

You have a Microsoft Power BI data model that contains three tables named Orders, Date, and City. There is a one-to-many relationship between Date and
Orders and between City and Orders.
The model contains two row-level security (RLS) roles named Role1 and Role2. Role1 contains the following filter.
City[State Province] = "Kentucky"
Role2 contains the following filter.
Date[Calendar Year] = 2020 -
If a user is a member of both Role1 and Role2, what data will they see in a report that uses the model?

A. The user will see data for which the State Province value is Kentucky or where the Calendar Year is 2020.

B. The user will receive an error and will not be able to see the data in the report.

C. The user will only see data for which the State Province value is Kentucky.

D. The user will only see data for which the State Province value is Kentucky and the Calendar Year is 2020.

 


Suggested Answer: D

Row-level security (RLS) with Power BI can be used to restrict data access for given users. Filters restrict data access at the row level, and you can define filters within roles.
Both Roles are applied, and both role filters must be met.
Incorrect:
Not B: A model relationship is limited when there’s no guaranteed “one” side. You get an error message if you belong to multiple RLS roles and at least one of the roles relies on a limited relationship. But here both relationships have a guaranteed 1 side.
Reference:
https://docs.microsoft.com/en-us/power-bi/enterprise/service-admin-rls

Question 6

You are creating a Power BI report by using Power BI Desktop.
You need to include a visual that shows trends and other useful information automatically. The visual must update based on selections in other visuals.
Which type of visual should you use?

A. Q&A

B. smart narrative

C. key influencers

D. decomposition tree

 


Suggested Answer: B

The smart narrative visualization helps you quickly summarize visuals and reports. It provides relevant innovative insights that you can customize.
Use smart narrative summaries in your reports to address key takeaways, to point out trends, and to edit the language and format for a specific audience. In
PowerPoint, instead of pasting a screenshot of your report’s key takeaways, you can add narratives that are updated with every refresh. Your audience can use the summaries to understand the data, get to key points faster, and explain the data to others.
Reference:
https://docs.microsoft.com/en-us/power-bi/visuals/power-bi-visualization-smart-narrative

Question 7

A user creates a Power BI report named ReportA that uses a custom theme.
You create a dashboard named DashboardA.
You need to ensure that DashboardA uses the custom theme. The solution must minimize development effort.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A. Publish ReportA to Power BI.

B. From ReportA save the current theme.

C. Publish ReportA to the Microsoft Power BI Community theme gallery.

D. From DashboardA, create a custom theme.

E. From DashboardA, upload a JSON theme.

 


Suggested Answer: AE

A: With Power BI Desktop report themes, you can apply design changes to your entire report, such as using corporate colors, changing icon sets, or applying new default visual formatting.
When you publish a Power BI Desktop file to the Power BI service, you publish the data in the model to your Power BI workspace. The same is true for any reports you created in Report view.
To publish a Power BI Desktop dataset and reports
1. In Power BI Desktop, choose File > Publish > Publish to Power BI or select Publish on the ribbon.
Sign in to Power BI, if you aren’t already signed in.
2. Select the destination. You can search your list of available workspaces to find the workspace into which you want to publish. The search box lets you filter your workspaces. Select the workspace, and then click the Select button to publish.
Reference Image
3. Etc.
E: One way to create a custom theme is to upload a JSON file that has settings for all the colors you’d like to use for your dashboard. In Power BI Desktop, report creators use JSON files to create themes for reports. You can upload these same JSON files for dashboards, or find and upload JSON files from the Theme gallery page in the Power BI Community.
You can also save your custom theme as a JSON file and then share it with other dashboard creators.

Question 8

Overview -
Litware, Inc. is an online retailer that uses Power BI.
Litware plans to leverage data from an Azure SQL database that stores data for the company's live e-commerce website.
Litware uses Azure Active Directory (Azure AD) to authenticate users.
Existing Environment. Sales Data
Litware has online sales data that has the SQL schema shown in the following table.
 Image
In the Date table, the date_id column has a format of yyyymmdd and the month column has a format of yyyymm.
The week column in the Date table and the week_id column in the Weekly_Returns table have a format of yyyyww.
In the Sales table, the sales_id column represents a unique transaction.
The region id column can be managed by only one sales manager.
Existing Environment. Data Concerns
You are concerned with the quality and completeness of the sales data. You must ensure that negative and missing sales_amount values do NOT contribute to the total sales amount calculation.
Existing Environment. Reporting Requirements
Litware identifies the following reporting requirements:
Executives require a visual that shows sales by region.
Executives require a visual that shows returns by region manager and the sales managers that report to them.
The sales managers must be able to see only the sales data of their respective region.
The sales managers require a visual to analyze sales performance versus sales targets.
The sales department requires reports that contain the number of sales transactions.
Users must be able to see the month in each report as shown in the following example: Feb 2020.
The customer service department requires a visual that can be filtered by both sales month and ship month independently.
The maximum allowed latency to include transactions in reports is five minutes.
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?

A. Create a DAX calculated column that retrieves the region manager from the Weekly_Returns table based on the sales_region_id column.

B. Apply row-level security (RLS) to the Region table based on the sales manager username.

C. Configure a bi-directional relationship between Region and Sales_Region.

D. In the Region table, create a hierarchy that has the manager name, and then the sales manager name.

 


Suggested Answer: A

Executives require a visual that shows returns by region manager and the sales managers that report to them.
A hierarchy is a set of fields categorized in a hierarchical way that one level is the parent of another level. Values of the parent level can be drilled down to the lower level.

Question 27

You need to create relationships to meet the reporting requirements of the customer service department.
What should you create?

A. a one-to-many relationship from Date[date_id] to Sales[sales_date_id] and another one-to-many relationship from Date[date_id] to Weekly_Returns[week_id]

B. a one-to-many relationship from Sales[sales_date_id] to Date[date_id] and a one-to-many relationship from Sales[sales_ship_date_id] to Date[date_id]

C. an additional date table named ShipDate, a many-to-many relationship from Sales[sales_date_id] to Date[date_id], and a many-to-many relationship from Sales[sales_ship_date_id] to ShipDate[date_id]

D. an additional date table named ShipDate, a one-to-many relationship from Date[date_id] to Sales[sales_date_id], and a one-to-many relationship from ShipDate[date_id] to Sales[sales_skip_date_id]

 


Suggested Answer: A

The customer service department requires a visual that can be filtered by both sales month and ship month independently.
Need two date tables. Add a one-to-many relationship from both the Date tables to Sales table.
Reference:
https://docs.microsoft.com/en-us/power-bi/guidance/relationships-active-inactive

Question 28

You have a Microsoft Power BI data model that contains three tables named Orders, Date, and City. There is a one-to-many relationship between Date and
Orders and between City and Orders.
The model contains two row-level security (RLS) roles named Role1 and Role2. Role1 contains the following filter.
City[State Province] = "Kentucky"
Role2 contains the following filter.
Date[Calendar Year] = 2020 -
If a user is a member of both Role1 and Role2, what data will they see in a report that uses the model?

A. The user will see data for which the State Province value is Kentucky or where the Calendar Year is 2020.

B. The user will receive an error and will not be able to see the data in the report.

C. The user will only see data for which the State Province value is Kentucky.

D. The user will only see data for which the State Province value is Kentucky and the Calendar Year is 2020.

 


Suggested Answer: D

Row-level security (RLS) with Power BI can be used to restrict data access for given users. Filters restrict data access at the row level, and you can define filters within roles.
Both Roles are applied, and both role filters must be met.
Incorrect:
Not B: A model relationship is limited when there’s no guaranteed “one” side. You get an error message if you belong to multiple RLS roles and at least one of the roles relies on a limited relationship. But here both relationships have a guaranteed 1 side.

Question 43

Overview -
Northwind Traders is a specialty food import company.
The company recently implemented Power BI to better understand its top customers, products, and suppliers.
Business Issues -
The sales department relies on the IT department to generate reports in Microsoft SQL Server Reporting Services (SSRS). The IT department takes too long to generate the reports and often misunderstands the report requirements.
Existing Environment. Data Sources
Northwind Traders uses the data sources shown in the following table.
 Image
Source2 is exported daily from a third-party system and stored in Microsoft SharePoint Online.
Existing Environment. Customer Worksheet
Source2 contains a single worksheet named Customer Details. The first 11 rows of the worksheet are shown in the following table.
 Image
All the fields in Source2 are mandatory.
The Address column in Customer Details is the billing address, which can differ from the shipping address.
Existing Environment. Azure SQL Database
Source1 contains the following tables:
Orders
Products
Suppliers
Categories
Order Details
Sales Employees
The Orders table contains the following columns.
 Image
The Order Details table contains the following columns.
 Image
The address in the Orders table is the shipping address, which can differ from the billing address.
The Products table contains the following columns.
 Image
The Categories table contains the following columns.
 Image
The Suppliers table contains the following columns.
 Image
The Sales Employees table contains the following columns.
 Image
Each employee in the Sales Employees table is assigned to one sales region. Multiple employees can be assigned to each region.
Requirements. Report Requirements
Northwind Traders requires the following reports:
Top Products
Top Customers
On-Time Shipping
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 report must also show which suppliers provide the top products.
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
Northwind Traders defines late orders as those shipped after the required shipping date.
The warehouse shipping department must be notified if the percentage of late orders within the current month exceeds 5%.
The reports must show historical data for the current calendar year and the last three calendar years.
Requirements. Technical Requirements
Northwind Traders identifies the following technical requirements:
A single dataset must support all three reports.
The reports must be stored in a single Power BI workspace.
Report data must be current as of 7 AM Pacific Time each day.
The reports must provide fast response times when users interact with a visualization.
The data model must minimize the size of the dataset as much as possible, while meeting the report requirements and the technical requirements.
Requirements. Security Requirements
Access to the reports must be granted to Azure Active Directory (Azure AD) security groups only. An Azure AD security group exists for each department.
The sales department must be able to perform the following tasks in Power BI:
Create, edit, and delete content in the reports.
Manage permissions for workspaces, datasets, and reports.
Publish, unpublish, update, and change the permissions for an app.
Assign Azure AD groups role-based access to the reports workspace.
Users in the sales department must be able to access only the data of the sales region to which they are assigned in the Sales Employees table.
Power BI has the following row-level security (RLS) Table filter DAX expression for the Sales Employees table.
[EmailAddress] = USERNAME()
RLS will be applied only to the sales department users. Users in all other departments must be able to view all the data.
You need to create the dataset.
Which dataset mode should you use?

A. Import

B. DirectQuery

C. Composite

D. live connection

 


Suggested Answer: C

The three dataset modes are:
Import –
DirectQuery –
Composite –
Composite mode –
Composite mode can mix Import and DirectQuery modes, or integrate multiple DirectQuery data sources. Models developed in Composite mode support configuring the storage mode for each model table. This mode also supports calculated tables (defined with DAX).
The table storage mode can be configured as Import, DirectQuery, or Dual. A table configured as Dual storage mode is both Import and DirectQuery, and this setting allows the Power BI service to determine the most efficient mode to use on a query-by-query basis.
Note: A single dataset must support all three reports.
The data model must minimize the size of the dataset as much as possible, while meeting the report requirements and the technical requirements.
Northwind Traders requires the following reports:
Top Products –
Top Customers –
On-Time Shipping –
Incorrect:
* DirectQuery mode is an alternative to Import mode. Models developed in DirectQuery mode don’t import data. Instead, they consist only of metadata defining the model structure. When the model is queried, native queries are used to retrieve data from the underlying data source.
* Import
However, while there are compelling advantages associated with Import models, there are disadvantages, too:
The entire model must be loaded to memory before Power BI can query the model, which can place pressure on available capacity resources, especially as the number and size of Import models grow

Question 44

You need to minimize the size of the dataset. The solution must meet the report requirements.
What should you do?

A. Group the Categories table by the CategoryID column.

B. Remove the QuantityPerUnit column from the Products table.

C. Filter out discontinued products while importing the Products table.

D. Change the OrderID column in the Orders table to the Text data type.

 


Suggested Answer: B

Removing a column which isn’t used in the reports reduces the dataset size.
Incorrect:
Not A: Grouping does not affect size.
Not C: Cannot filter out discontinued products as: The reports must show historical data for the current calendar year and the last three calendar years.
Not D: OrderID must be Integer.

Question 45

DRAG DROP
-
You have the Power BI data model shown in the following exhibit.
 Image
The Country table contains the following data.

You need to create DAX expressions for the RLS filters. The solution must meet the following requirements:
•	Each manager must see only the data in the Sales and Human Resources tables for their own country.
•	The CFO must be prevented from seeing the data in the Human Resources table.
•	The CFO must see the sales data of all countries.
How should you complete the DAX expressions to meet the requirements? To answer, drag the appropriate expressions to the correct targets. Each expression may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Question 47

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?

A. decomposition tree

B. funnel chart

C. Q&A

D. key influencers

 


Suggested Answer: A

The decomposition tree visual in Power BI lets you visualize data across multiple dimensions. It automatically aggregates data and enables drilling down into your dimensions in any order. It is also an artificial intelligence (AI) visualization, so you can ask it to find the next dimension to drill down into based on certain criteria.
This makes it a valuable tool for ad hoc exploration and conducting root cause analysis.
