QUESTION 1:
You have a Power BI report. The report contains visualizations that have interactions.
You need to identify which visualizations take the longest to complete.
What should you use?
A. Query Diagnostics in Power BI
B. Performance Analyzer in Power BI Desktop
C. SQL Server Profiler
D. Microsoft Edge DevTools
Correct Answer: B
Use Power BI Desktop Performance Analyzer to optimize reports.
In Power BI Desktop you can find out how each of your report elements, such as visuals and DAX formulas, are performing. Using the Performance Analyzer, you can see and record logs that measure how each of your report elements performs when users interact with them, and which aspects of their performance are most (or least) resource intensive.

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. Request that the sales manager be added to the correct Azure Active Directory group.
D. Manage the permissions of the underlying dataset.
Correct Answer: C
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.

You need to automate the notifications.
What should you do?
A. Share the dashboard with the user.
B. Create a subscription.
C. Create a data alert.
D. Tag the user in a comment.
Correct Answer: B
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:
1.
Decide how often you want to receive the emails: daily, weekly, hourly, monthly, or once a day after the initial data refresh.
2.
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.

Splitter.SplitTextByDelimiter(“,”,QuoteStyle.None), let itemType = (type nullable text) meta[Serialized.Text = true] in type
{itemType}}}), “classes”)
Correct Answer: B
Power Query Unpivot columns: You might want to unpivot data, sometimes called flattening the data, to put it in a matrix format so that all similar values are in one column. This is necessary, for example, to create a chart or a report.
Note:
Syntax: Table.Unpivot(table as table, pivotColumns as list, attributeColumn as text, valueColumn as text) as table
Table. Unpivot translates a set of columns in a table into attribute-value pairs, combined with the rest of the values in each row.

QUESTION 10:
You have a sales system that contains the tables shown in the following table.
The Date table is marked as a date table. DateID is the date data type. You need to create an annual sales growth percentage measure. Which DAX expression should you use?
A. SUM(sales[sales_amount]) – CALCULATE(SUM(sales[sales_amount]), SAMEPERIODLASTYEAR(\’Date\'[DateID])
B. (SUM(‘Sales’[sales_amount]) – CALCULATE(SUM(‘Sales’[sales_amount]),
SAMEPERIODLASTYEAR(‘Date’[DateID])))/ CALCULATE(SUM(‘Sales’[sales_amount]),
SAMEPERIODLASTYEAR(‘Date’[DateID]))
C. CALCULATE(SUM(sales[sales_amount]), DATESYTD(‘Date’[DateID]))
D. CALCULATE(SUM(sales[sales_amount]), SAMEPERIODLASTYEAR(‘Date’[DateID]))

QUESTION 11:
HOTSPOT
You have two Azure SQL databases that contain the same tables and columns.
For each database, you create a query that retrieves data from a table named Customer.
You need to determine the Customer tables into a single table. The solution must minimize the size of the data model and support scheduled refresh in powerbi.com.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Box 1: Append Queries as New.
There are two primary ways of combining queries: merging and appending.
1.
When you have one or more columns that you’d like to add to another query, you merge the queries.
2.
When you have additional rows of data that you’d like to add to an existing query, you append the query.
Box 2: Disable loading the query to the data model
For every query that loads into the model, memory will be consumed. and Memory is our asset in the Model, less memory consumption leads to better performance in most cases. The best approach is to disable loading.
Reference: https://docs.microsoft.com/en-us/power-query/append-queries
QUESTION 12:
You use an R visual to produce a map of 500,000 customers. You include the values of CustomerID, Latitude, and Longitude in the fields sent to the visual. Each customer ID is unique.
In powerbi.com, when users load the visual, they only see some of the customers.
What is the cause of the issue?
A. The visual was built by using a different version of R.
B. The data comes from a Microsoft SQL Server source.
C. The data is deduplicated.
D. Too many records were sent to the visual.
Correct Answer: D
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 13:
DRAG DROP
You need to create a DAX measure in the data model that only allows users to see projections at the appropriate level of granularity.
How should you complete the measure? 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:
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.
Box 3: SUM
