Case Study

To start the case study

Overview

Contoso, Ltd. is a manufacturing company that produces outdoor equipment. Contoso has quarterly board meetings for which financial analysts manually prepare Microsoft Excel reports, including profit and loss statements for each of the company’s four business units, a company balance sheet, and net income projections for the next quarter.

Existing Environment Data and Sources

Data for the reports comes from three sources. Detailed revenue, cost, and expense data comes from an Azure SQL database. Summary balance sheet data comes from Microsoft Dynamics 365 Business Central. The balance sheet data is not related to the profit and loss results, other than they both relate dates.

Monthly revenue and expense projections for the next quarter come from a Microsoft SharePoint Online list. Quarterly projections relate to the profit and loss results by using the following shared dimensions: date, business unit, department, and product category.

Net Income Projection Data

Net income projection data is stored in a SharePoint Online list named Projections in the format shown in the following table.

Revenue projections are set at the monthly level and summed to show projections for the quarter.

Balance Sheet Data

The balance sheet data is imported with final balances for each account per month in the format shown in the following table.

There is always a row for each account for each month in the balance sheet data.

Dynamics 365 Business Central Data

Business Central contains a product catalog that shows how products roll up to product categories, which roll up to business units.

Revenue data is provided at the date and product level. Expense data is provided at the date and department level.

Business Issues

Historically, it has taken two analysts a week to prepare the reports for the quarterly board meetings. Also, there is usually at least one issue each quarter where a value in a report is wrong because of a bad cell reference in an Excel formula. On occasion, there are conflicting results in the reports because the products and departments that roll up to each business unit are not defined consistently.

Requirements Planned Changes

Contoso plans to automate and standardize the quarterly reporting process by using Microsoft Power BI. The company wants to how long it takes to populate reports to less than two days. The company wants to create common logic for business units, products, and departments to be used across all reports, including, but not limited, to the quarterly reporting for the board.

Technical Requirements

Contoso wants the reports and datasets refreshed with minimal manual effort.

The company wants to provide a single package of reports to the board that contains custom navigation and links to supplementary information.

Maintenance, including manually updating data and access, must be minimized as much as possible.

Security Requirements

The reports must be made available to the board from powerbi.com. A mail-enabled security group will be used to share information with the board.

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, but any reports that the analysts build must not be included in the quarterly reports for the board. The analysts must not be able to share the quarterly reports with anyone.

Report Requirements

You plan to relate the balance sheet to a standard date table in Power BI in a many-to-one relationship based on the last day of the month. 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.

Projections must contain a column named RevenueProjection that contains the revenue projection amounts. A relationship must be created from Projections to a table named Date that contains the columns shown in the following table.

The definitions and attributes of products, departments, and business units must be consistent across all reports.

The board must be able to get the following information from the quarterly reports:

Revenue trends over time

Ending balances for each account

A comparison of expenses versus projections by quarter Changes in long-term liabilities from the previous quarter

A comparison of quarterly revenue versus the same quarter during the prior year

Create a column by example that starts with 2018-12-31 and set the data type of the new column to

Date.

Apply a transform to extract the first 11 characters of the Logged column.

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

To use a built-in-date hierarchy, you need to set the data type of the new column to Date.

Incorrect Answers:

D: To use a transform, you would have to select the ‘Split’ option, not the ‘Extract’ option.

QUESTION 11

You have an Azure SQL database that contains sales transactions. The database is updated frequently.

You need to generate reports from the data to detect fraudulent transactions. The data must be visible within five minutes of an update.

How should you configure the data connection?

Add a SQL statement.
Set Data Connectivity mode to DirectQuery.
Set the Command timeout in minutes setting.
Set Data Connectivity mode to Import.

Correct Answer: B Section: (none) Explanation

Explanation/Reference:

Explanation:

With Power BI Desktop, when you connect to your data source, it’s always possible to import a copy of the data into the Power BI Desktop. For some data sources, an alternative approach is available: connect directly to the data source using DirectQuery.

DirectQuery: No data is imported or copied into Power BI Desktop. For relational sources, the selected tables and columns appear in the Fields list. For multi-dimensional sources like SAP Business Warehouse, the dimensions and measures of the selected cube appear in the Fields list. As you create or interact with a visualization, Power BI Desktop queries the underlying data source, so you’re always viewing current data.

Incorrect Answers:

D: Import: The selected tables and columns are imported into Power BI Desktop. As you create or interact with a visualization, Power BI Desktop uses the imported data. To see underlying data changes since the initial import or the most recent refresh, you must refresh the data, which imports the full dataset again.

Reference:

https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-use-directquery

QUESTION 12

You have a data model that contains many complex DAX expressions. The expressions contain frequent references to the RELATED and RELATEDTABLE functions.

You need to recommend a solution to minimize the use of the RELATED and RELATEDTABLE functions. What should you recommend?

Split the model into multiple models.
Hide unused columns in the model.
Merge tables by using Power Query.
Transpose.

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

Combining data means connecting to two or more data sources, shaping them as needed, then consolidating them into a useful query.

When you have one or more columns that you’d like to add to another query, you merge the queries.

Note: The RELATEDTABLE function is a shortcut for CALCULATETABLE function with no logical expression.

CALCULATETABLE evaluates a table expression in a modified filter context and returns A table of values.

Reference:

https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-shape-and-combine-data

QUESTION 13

You have a large dataset that contains more than 1 million rows. The table has a datetime column named Date.

You need to reduce the size of the data model. What should you do?

Round the hour of the Date column to startOfHour.
Change the data type of the Date column to Text.
Trim the Date column.
Split the Date column into two columns, one that contains only the time and another that contains only the date.

Correct Answer: D Section: (none) Explanation

Explanation/Reference:

Explanation: We have to separate date & time tables. Also, we don’t need to put the time into the date table, because the time is repeated every day.

Split your DateTime column into a separate date & time columns in fact table, so that you can join the date to the date table & the time to the time table. The time need to be converted to the nearest round minute or second so that every time in your data corresponds to a row in your time table.

You need to provide end users with access to the summary statistics about the SalesDetail data. The users require insights on the completeness of the data and the value distributions.

Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order,

Select and Place:

Correct Answer:

Section: (none) Explanation

Explanation/Reference:

Explanation:

Step 1: Create a blank query as a data source

Start with a New Source in Power Query Editor, and then Blank Query.

Create a parameter that use a query for suggested values.

Step 2: Specify the following query, then close and apply. -Table.Profile(#¨SalesDetail”)

In the new blank query, in the formula bar (if you don’t see the formula bar, check the formula bar option in the View tab of the Power Query Editor), type below expression:

=Table.Profile()

Note that this code is not complete yet, we need to provide a table as the input of this function.

Note: The Table.Profile() function takes a value of type table and returns a table that displays, for each column in the original table, the minimum, maximum, average, standard deviation, count of values, count of null values and count of distinct values.

Step 3: Create a visual for the query table.

The profiling data that you get from Table.Profile function is like below;

After loading the data into Power BI, you’ll have the table with all columns, and it can be used in any visuals.

QUESTION 16

You have a Microsoft Power BI report. The size of PBIX file is 550 MB. The report is accessed by using an App workspace in shared capacity of powerbi.com.

The report uses an imported dataset that contains one fact table. The fact table contains 12 million rows. The dataset is scheduled to refresh twice a day at 08:00 and 17:00.

The report is a single page that contains 15 AppSource visuals and 10 default visuals.

Users say that the report is slow to load the visuals when they access and interact with the report. You need to recommend a solution to improve the performance of the report.

What should you recommend?

Change any DAX measures to use iterator functions.
Replace the default visuals with AppSource visuals.
Change the imported dataset to DirectQuery.
Remove unused columns from tables in the data model.

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

DirectQuery: No data is imported or copied into Power BI Desktop.

Import: The selected tables and columns are imported into Power BI Desktop. As you create or interact with a visualization, Power BI Desktop uses the imported data.

Benefits of using DirectQuery

There are a few benefits to using DirectQuery:

DirectQuery lets you build visualizations over very large datasets, where it would otherwise be

unfeasible to first import all the data with pre-aggregation.

Underlying data changes can require a refresh of data. For some reports, the need to display current data can require large data transfers, making reimporting data unfeasible. By contrast, DirectQuery reports always use current data.

The 1-GB dataset limitation doesn’t apply to DirectQuery.

Note:

There are several versions of this question in the exam. The question can have other incorrect answer options, include the following:

Implement row-level security (RLS)

Increase the number of times that the dataset is refreshed.

QUESTION 17

You create a dashboard by using the Microsoft Power BI Service. The dashboard contains a card visual that shows total sales from the current year.

You grant users access to the dashboard by using the Viewer role on the workspace. A user wants to receive daily notifications of the number shown on the card visual.

You need to automate the notifications. What should you do?

Create a data alert.
Share the dashboard to the user.
Create a subscription.
Tag the user in a comment.

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

You can subscribe yourself and your colleagues to the report pages, dashboards, and paginated reports that matter most to you. Power BI e-mail subscriptions allow you to:

Decide how often you want to receive the emails: daily, weekly, hourly, monthly, or once a day after the initial data refresh.

Choose the time you want to receive the email, if you choose daily, weekly, hourly, or monthly.

Note: Email subscriptions don’t support most custom visuals. The one exception is those custom visuals that have been certified.

Email subscriptions don’t support R-powered custom visuals at this time.

Incorrect Answers:

A: Set data alerts to notify you when data in your dashboards changes beyond limits you set.

Case Study

To start the case study

Overview

Litware, Inc. is an online retailer that uses Microsoft Power BI dashboards and reports.

The company plans to leverage data from Microsoft SQL Server databases, Microsoft Excel files, text files, and several other data sources.

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.

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.

The sales_id column in the Sales table represents a unique transaction. The region_id column can be managed by only one sales manager.

Data Concerns

You are concerned with the quality and completeness of the sales data. You plan to verify the sales data for negative sales amounts.

Reporting Requirements

Litware identifies the following technical requirements:

Executives require a visual that shows sales by region.

Regional managers require a visual to analyze weekly sales and returns.

Sales managers must be able to see the sales data of their respective region only.

The sales managers require a visual to analyze sales performance versus sales targets. The sale department requires reports that contain the number of sales transactions.

Users must be able to see the month in reports 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.

QUESTION 1

You need to provide a solution to provide the sales managers with the required access. What should you include in the solution?

Create a security role that has a table filter on the Sales_Manager table where

username = UserName().

Create a security role that has a table filter on the Region_Manager table where

sales_manager_id = UserPrincipalName().

Create a security role that has a table filter on the Sales_Manager table where

name = UserName().

Create a security role that has a table filter on the Sales_Manager table where

username = sales_manager_id.

Correct Answer: B Section: (none) Explanation

Explanation/Reference:

Explanation:

Scenario: The region_id column can be managed by only one sales manager.

You can use Username() or userprincipalname() in DAX with Row-Level Security.

Within Power BI Desktop, username() will return a user in the format of DOMAIN\User and userprincipalname() will return a user in the format of user@contoso.com.

Reference:

https://docs.microsoft.com/en-us/power-bi/admin/service-admin-rls

QUESTION 2

You need to create a relationship between the Weekly_Returns table and the Date table to meet the reporting requirements of the regional managers.

What should you do?

Add the Weekly_Returns data to the Sales table by using RELATED DAX functions.
In the Weekly_Returns table, create a new calculated column named date_id in a format of

yyyymmdd and use the calculated column to create a relationship to the Date table.

Create a new table based on the Date table where date_id is unique, and then create a many-to-many relationship to Weekly_Return.

Correct Answer: B Section: (none) Explanation

Explanation/Reference:

Explanation:

Scenario: Regional managers require a visual to analyze weekly sales and returns. To relate the two tables we need a common column.

QUESTION 3

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

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_ship_date_id]
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]

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]
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]

Correct Answer: A Section: (none) Explanation

Explanation/Reference:

Explanation:

Scenario: The customer service department requires a visual that can be filtered by both sales month and ship month independently.

In Power BI Desktop, only one relationship can be active between a Fact table and Dimension table, so we need an extra table.

Use one-to-many relationship to be able to filter. Incorrect Answers:

C: Cannot make a relation between a date_id and a week_id.

D: The one-to-many relationships between the Sales and the Date tables goes in the other direction: for each date there can be many sales or shipments.

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 distribution lists 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?

Change the Microsoft Power BI license type of the sales manager.
From Microsoft Power BI Desktop, edit the Row-Level Security setting for the reports.
Request that the sales manager be added to the correct Azure Active Directory group.
Manage the permissions of the underlying dataset.

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

Using AD Security Groups, you no longer need to maintain a long list of users.

All that you will need to do is to put in the AD Security group with the required permissions and Power BI will do the REST! This means a small and simple security file with the permissions and AD Security group.

Note: Configure role mappings

Once published to Power BI, you must map members to dataset roles.

Members can be user accounts or security groups. Whenever possible, we recommend you map security groups to dataset roles. It involves managing security group memberships in Azure Active Directory.

Possibly, it delegates the task to your network administrators.

QUESTION 3

DRAG DROP

You have a Microsoft Power BI data model that contains three tables named Sales, Product, and Date.

The Sales table has an existing measure named [Total Sales] that sums the total sales from the Sales table.

You need to write a calculation that returns the percentage of total sales that a selected ProductCategoryName value represents. The calculation must respect any slicers on ProductCategoryName and must show the percentage of visible total sales. For example, if there are four ProductCategoryName values, and a user filters one out, a table showing ProductCategoryName and the calculation must sum up to 100 percent.

How should you complete the calculation? To answer, drag the appropriate values to the correct targets. Each value 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.

NOTE: Each correct selection is worth one point.

Select and Place:

Correct Answer:

Section: (none) Explanation

Explanation/Reference:

Explanation:

Box 1: CALCULATE

CALCULATE rvaluates an expression in a modified filter context.

Box 2: DIVIDE

As a data modeler, when you write a DAX expression to divide a numerator by a denominator, you can choose to use the DIVIDE function or the divide operator (/ – forward slash).

When using the DIVIDE function, you must pass in numerator and denominator expressions. Box 3: ALLSELECTED

ALLSELECTED removes context filters from columns and rows in the current query, while retaining all other context filters or explicit filters.

The ALLSELECTED function gets the context that represents all rows and columns in the query, while keeping explicit filters and contexts other than row and column filters. This function can be used to obtain visual totals in queries.

Example:

measure ‘Reseller Sales'[Reseller Visual Total]=calculate(sum(‘Reseller Sales'[Sales Amount]), ALLSELECTED())

Reference:

https://docs.microsoft.com/en-us/dax/allselected-function-dax

QUESTION 4

You have sales data in a star schema that contains four tables named Sales, Customer, Date, and Product. The Sales table contains purchase and ship dates.

Most often, you will use the purchase date to analyze the data, but you will analyze the data by both dates independently and together.

You need to design an imported dataset to support the analysis. The solution must minimize the model size

and the number of queries against the data source. Which data modeling design should you use?

Use the Auto Date/Time functionality in Microsoft Power BI and do NOT import the Date table.
Duplicate the Date query in Power Query and use active relationships between both Date tables.
On the Date table, use a reference query in Power Query and create active relationships between Sales and both Date tables in the modeling view.
Create an active relationship between Sales and Date for the purchase date and an inactive relationship for the ship date.

Correct Answer: D Section: (none) Explanation

Explanation/Reference:

Explanation:

Only one relationship can be active.

Note: If you query two or more tables at the same time, when the data is loaded, Power BI Desktop attempts to find and create relationships for you. The relationship options Cardinality, Cross filter direction, and Make this relationship active are automatically set.

In powerbi.com, when users load the visual, they only see some of the customers. What is the cause of the issue?

The visual was built by using a different version of R.
The data comes from a Microsoft SQL Server source.
The data is deduplicated.
Too many records were sent to the visual.

Correct Answer: D Section: (none) Explanation

Explanation/Reference:

Explanation:

R visuals in the Power BI service have a few limitations including:

Data size limitations – data used by the R visual for plotting is limited to 150,000 rows. If more than 150,000 rows are selected, only the top 150,000 rows are used and a message is displayed on the image. Additionally, the input data has a limit of 250 MB.

QUESTION 2

You have a line chart that shows the number of employees in a department over time. You need to see the total salary costs of the employees when you hover over a data point.

What are two possible ways to achieve this goal? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Add a salary to the tooltips.
Add a salary to the visual filters.
Add salary to the drillthrough fields.

Correct Answer: AB Section: (none) Explanation

Explanation/Reference:

Explanation:

A: When a visualization is created, the default tooltip displays the data point’s value and category. There are many instances when customizing the tooltip information is useful. Customizing tooltips provides additional context and information for users viewing the visual. Custom tooltips enable you to specify additional data points that display as part of the tooltip.

B: Visual Filter applies to a single visual/tile on a report page. You can only see visual level filters selected visual on the report canvas.

Incorrect Answers:

C: With drill through in Power BI reports, you can create a page in your report that focuses on a specific entity such as a supplier, customer, or manufacturer. When your report readers use drill through, they right- click a data point in other report pages, and drill through to the focused page to get details that are filtered

to that context. You can also create a button that drills through to details when they click it.

QUESTION 3

You have a report that contains a bar chart and a column chart. The bar chart shows customer count by customer segment. The column chart shows sales by month.

You need to ensure that when a segment is selected in the bar chart, you see which portion of the total sales for the month belongs to the customer segment.

How should the visual interactions be set on the column chart when the bar chart is selected?

no impact
highlight
filter

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

Filters remove all but the data you want to focus on. Highlighting isn’t filtering. It doesn’t remove data, but instead highlights a subset of the visible data; the data that isn’t highlighted remains visible but dimmed.

QUESTION 5

DRAG DROP

You are using existing reports to build a dashboard that will be viewed frequently in portrait mode on mobile phones.

You need to build the dashboard.

Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Select and Place:

Correct Answer:

Section: (none) Explanation

Explanation/Reference:

Explanation:

When you view dashboards in portrait mode on a phone, you notice the dashboard tiles are laid out one after another, all the same size. In the Power BI service, you can create a customized view of a dashboard, specifically for portrait mode on phones.

Step 1: Open the Dashboard.

Step 2: Change the dashboard view to Phone view Step 3: Pin items from the reports to the dashboard.

Step 4: Rearrange, resize, or remote items from the Phone view.

Create a phone view of a dashboard

In the Power BI service, open a dashboard (Step 1)
Select the arrow next to Web view in the upper-right corner > select Phone view. (Step 2)

The phone dashboard edit view opens. Here you can unpin, resize, and rearrange tiles to fit the phone view. The web version of the dashboard doesn’t change.

Select a tile to drag, resize, or unpin it. You notice the other tiles move out of the way as you drag a tile. The unpinned tiles go in the Unpinned tiles pane, where they stay unless you add them back.
If you change your mind, select Reset tiles to put them back in the size and order they were before.
When you’re satisfied with the phone dashboard layout, select the arrow next to Phone view in the upper- right corner > select Web view.

Power BI saves the phone layout automatically. Reference:

QUESTION 6

You build a report to help the sales team understand its performance and the drivers of sales. The team needs to have a single visualization to identify which factors affect success.

Which type of visualization should you use?

Line and clustered column chart
Key influencers
Q&A
Funnel chart

Correct Answer: B

Section: (none)

Explanation

Explanation/Reference:

Explanation:

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.

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 have more impact on churn than long-term contracts?

Box 1: A scatter plot…

A scatter chart always has two value axes to show: one set of numerical data along a horizontal axis and another set of numerical values along a vertical axis. The chart displays points at the intersection of an x and y numerical value, combining these values into single data points. Power BI may distribute these data points evenly or unevenly across the horizontal axis. It depends on the data the chart represents.

Box 2: Automatically find clusters

Scatter charts are a great choice to show patterns in large sets of data, for example by showing linear or non-linear trends, clusters, and outliers.

QUESTION 9

You have the dataset shown in the following exhibit.

You need to ensure that the visual shows only the 10 cities that have the highest sales profit. What should you do?

Add a Top N filter to the visual.
Configure the Sales Profit measure to use the RANKX function.
Add a calculated column to the table that uses the TOPN function. In the visual, replace Sales Profit with the calculated column.
Add a calculated column to the table that returns the city name if the city is in the top 10, otherwise the calculated column will return “Not in Top 10”. In the visual, replace Sales Profit with the calculated column.

Correct Answer: A Section: (none) Explanation

Explanation/Reference:

Explanation:

Power BI Top N Filters are useful to display the top performing records, and Bottom N filters are helpful to display the least performing records. For example, we can display top or bottom 10 products by orders or

sales.

Note:

Select the Column you want to display the Top Sales Profit
Then change the Filter Type of that Column to Top N
Fill in Top / Bottom number field
And lastly drag to the By Value filed your Sales Profit

Explanation:

Box 1: cross-filter

By default, selecting a data point in one visual on a report page will cross-filter or cross-highlight the other visuals on the page.

Box 2: cross-highlight Example:

By default, selecting a data point in one visual on a report page will cross-filter or cross-highlight the other visuals on the page.

Let’s see what happens when we select Moderation.

Cross-filtering removes data that doesn’t apply. Selecting Moderation in the doughnut chart cross-filters the line chart. The line chart now only displays data points for the Moderation segment.
Cross-highlighting retains all the original data points but dims the portion that does not apply to your selection. Selecting Moderation in the doughnut chart cross-highlights the column chart. The column chart dims all the data that applies to the Convenience segment and highlights all the data that applies to the Moderation segment.

Add percentile lines to monitor daily revenue

Incorrect Answers:

A, D: There are two main percentile functions in Power BI:

PERCENTILE.EXC(column, kth percentile) PERCENTILE.INC(column, kth percentile)

The first parameter is the column which you want the percentile value for.

The second parameter is the kth percentile where k percentage of values will fall below.

Both formulas use a slightly different algorithm. The second algorithm works for any value of k between 0 and 1 (the 0th and 100th percentile). In the EXC version the data excludes both lower and upper bounds, while INC includes them.

Correct Answer: C

Section: (none) Explanation

Explanation/Reference:

Explanation:

A line chart or line graph displays the evolution of one or several numeric variables. Data points are connected by straight line segments. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically.

Example:

Incorrect Answers:

A: Stacked area charts are not appropriate to study the evolution of each individual group: it is very hard to substract the height of other groups at each time point.

Note: A stacked area chart is the extension of a basic area chart. It displays the evolution of the value of several groups on the same graphic. The values of each group are displayed on top of each other, what allows to check on the same figure the evolution of both the total of a numeric variable, and the importance of each group.

What should you implement?

dataset certifications
row-level security (RLS)
sensitivity labels
Microsoft Intune policies

Correct Answer: C Section: (none) Explanation

Explanation/Reference:

Explanation:

General availability of sensitivity labels in Power BI.

Microsoft Information Protection sensitivity labels provide a simple way for your users to classify critical content in Power BI without compromising productivity or the ability to collaborate. Sensitivity labels can be applied on datasets, reports, dashboards, and dataflows. When data is exported from Power BI to Excel, PowerPoint or PDF files, Power BI automatically applies a sensitivity label on the exported file and protects it according to the label’s file encryption settings. This way your sensitive data remains protected no matter where it is.

QUESTION 5

You have a collection of reports for the HR department of your company. The datasets use row-level security (RLS). The company has multiple sales regions that each has an HR manager.

You need to ensure that the HR managers can interact with the data from their region only. The HR managers must be prevented from changing the layout of the reports.

How should you provision access to the reports for the HR managers?

Publish the reports to a different workspace other than the one hosting the datasets.
Publish the reports in an app and grant the HR managers access permission.
Add the HR managers as members of the existing workspace that hosts the reports and the datasets.
Create a new workspace, copy the datasets and reports, and add the HR managers as members of the workspace.

Correct Answer: A Section: (none) Explanation

Explanation/Reference:

Explanation:

Note: 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. In the Power BI service, members of a workspace have access to datasets in the workspace. RLS doesn’t restrict this data access.

QUESTION 6

You create a report by using Microsoft Power BI Desktop.

The report uses data from a Microsoft SQL Server Analysis Services (SSAS) cube located on your company’s internal network.

You plan to publish the report to the Power BI Service.

What should you implement ta ensure that users who consume the report from the Power BI Service have the most up-to-date data from the cube?

a subscription
a scheduled refresh of the dataset
an OData feed
an On-premises data gateway

Correct Answer: D Section: (none) Explanation

Explanation/Reference:

Explanation:

When you’ve created dynamic reports in Power BI Desktop, you can share them by publishing to your Power BI site. When you publish a Power BI Desktop file with a live connection to a tabular model to your Power BI site, an on-premises data gateway must be installed and configured by an administrator.

QUESTION 9

You publish a Microsoft Power BI dataset to powerbi.com. The dataset appends data from an on-premises Oracle database and an Azure SQL database by using one query.

You have admin access to the workspace and permission to use an existing On-premises data gateway for which the Oracle data source is already configured.

You need to ensure that the data is updated every morning. The solution must minimize configuration effort.

Which two actions should you perform when you configure scheduled refresh? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Configure the dataset to use the existing On-premises data gateway.
Deploy an On-premises data gateway in personal mode.
Set the refresh frequency to Daily.
Configure the dataset to use the personal gateway.

Correct Answer: BC Section: (none) Explanation

Explanation/Reference:

Explanation:

B: The on-premises data gateway acts as a bridge to provide quick and secure data transfer between on- premises data (data that isn’t in the cloud) and several Microsoft cloud services. These cloud services include Power BI.

On-premises data gateway (personal mode) allows one user to connect to sources, and can’t be shared with others. An on-premises data gateway (personal mode) can be used only with Power BI. This gateway is well-suited to scenarios where you’re the only person who creates reports, and you don’t need to share any data sources with others.

C: For Power BI users, refreshing data typically means importing data from the original data sources into a dataset, either based on a refresh schedule or on-demand. You can perform multiple dataset refreshes daily, which might be necessary if the underlying source data changes frequently.

Incorrect Answers:

A: On-premises data gateway allows multiple users to connect to multiple on-premises data sources. You can use an on-premises data gateway with all supported services, with a single gateway installation. This gateway is well-suited to complex scenarios with multiple people accessing multiple data sources.

QUESTION 12

You create a dataset sourced from dozens of flat files in Azure Blob storage. The dataset uses incremental refresh.

From powerbi.com, you deploy the dataset and several related reports to Microsoft Power BI Premium capacity.

You discover that the dataset refresh fails after the refresh runs out of resources. What is a possible cause of the issue?

Query folding is not occurring.
You selected Only refresh complete periods.
The data type of the column used to partition the data changed.
A filter is missing on the report.

Correct Answer: A Section: (none) Explanation

Explanation/Reference:

Explanation:

The Power BI service partitions data based on date range. This is what enables only certain partitions to be refreshed incrementally. To make this work, the partition filter conditions are pushed down to the source system by including them in the queries. Using Power Query terminology, this is called “query folding”. It is not recommended that incremental refresh is used when the required query folding cannot take place.
