PL-300 Multiple Select — 20 Questions

Question 1

You are connecting to a data source that contains Personally Identifiable Information (PII). You need to ensure that only authorized users can view the data in Power BI reports. Which TWO actions should you take?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Define row-level security (RLS) roles in Power BI Desktop.. Row-Level Security (RLS) allows you to restrict data access at the row level based on user roles defined in Power BI Desktop. By creating roles and using DAX filters, you can ensure that only authorized users see specific rows of PII data when the report is published to the Power BI service and users are mapped to roles.

Answer

Enable encryption at rest for the dataset.

Answer

Use Power Query to mask PII columns by replacing values with '***'.

Answer

Apply sensitivity labels to the dataset.

Question 2

Which TWO DAX functions can be used to filter data in a measure?

Accepted Answer

FILTER. (FILTER) is correct because it is a DAX function specifically designed to return a filtered subset of a table based on a logical condition, making it a primary tool for row-level filtering within measures. Option E (CALCULATE) is correct because it modifies the filter context of a measure by applying or removing filters, effectively filtering data through its filter arguments. Both functions directly control which rows are included in calculations.

Answer

VALUES

Answer

SUM

Answer

ALL

Question 3

Which TWO are best practices for optimizing Power Query performance? (Choose two.)

Accepted Answer

Disable the 'Enable background refresh' option in the query settings.. Disabling 'Enable background refresh' prevents Power Query from running queries in the background while you continue working in Power BI Desktop. This ensures that query execution is synchronous, which can improve performance by avoiding resource contention and allowing you to monitor progress directly. Background refresh can cause delays and unexpected behavior when multiple queries run simultaneously, especially with large data sources.

Answer

Merge tables as early as possible in the query to combine data.

Answer

Keep all columns in the table to avoid missing data.

Answer

Split columns by delimiter to normalize data.

Question 4

Which THREE of the following are best practices for optimizing data load performance in Power BI?

Accepted Answer

Remove unnecessary columns and rows during the import process.. Removing unnecessary columns and rows during the import process reduces the amount of data loaded into the Power BI data model, which directly decreases memory usage and refresh time. By filtering out irrelevant data early in Power Query, you minimize the data volume that must be processed and stored, leading to faster load performance.

Answer

Split a large fact table into multiple smaller fact tables.

Answer

Use DirectQuery mode instead of Import mode to reduce data load time.

Question 5

Which TWO of the following are valid DAX functions for time intelligence? (Select two.)

Accepted Answer

DATEADD. DATEADD is a valid DAX time intelligence function that shifts dates forward or backward by a specified number of intervals (days, months, quarters, years). TOTALYTD is also a valid time intelligence function that calculates the year-to-date value of an expression. Both are part of the dedicated time intelligence function set in DAX, which requires a properly marked date table with continuous dates.

Answer

RANKX

Answer

CONCATENATEX

Answer

MINX

Question 6

Which THREE settings should you verify in the Power BI tenant admin portal to ensure that external users (guests) can access a published app?

Accepted Answer

Invite external users to your organization via Microsoft Entra ID.. To allow external users (guests) to access a published app in Power BI, three tenant settings must be enabled: 'Invite external users' (A) allows inviting guest users, 'Allow Azure AD external identities to access the Power BI service' (C) enables guest sign-in, and 'Allow sharing with external users' (B) permits sharing content with guests. Option E ('Allow external users to edit and manage content') is not required for viewing an app; it grants additional editing permissions. Option D controls whether guests appear in people pickers, which is unrelated.

Answer

Show external users in lists of suggested people.

Answer

Allow external users to edit and manage content in the organization.

Question 7

Which TWO of the following are valid data source types in Power BI that support DirectQuery? (Select TWO.)

Accepted Answer

Snowflake. Snowflake is a cloud-based data warehouse that supports DirectQuery in Power BI, allowing queries to be sent directly to Snowflake without importing data into Power BI's in-memory engine. This is possible because Snowflake provides a SQL-based interface that Power BI can connect to via its native connector, enabling real-time querying of large datasets.

Answer

Excel workbook

Answer

SharePoint Online List

Answer

JSON file

Question 8

Which TWO of the following are true about using the 'Mark as Date Table' feature in Power BI?

Accepted Answer

The date table must have a column with unique date values. Options C and E are correct. Option C is correct because the 'Mark as Date Table' feature requires the designated date column to contain unique, non-duplicate date values to function properly. Option E is correct because marking a date table enables time intelligence functions like TOTALYTD, which rely on a properly marked date table for accurate calculations. Option A is wrong because the feature is not required for relationships involving a date column; relationships can exist without marking a date table. Option B is wrong because the date column must have unique dates, not duplicate ones. Option D is wrong because marking a date table does not automatically create all date hierarchy columns; it only designates the table as the date table, and hierarchies must be created manually or through other means.

Answer

It is required for any relationship involving a date column

Answer

The date column can contain duplicate dates

Answer

It automatically creates all date hierarchy columns (Year, Quarter, Month, Day)

Question 9

You need to audit Power BI activities such as viewing reports, sharing dashboards, and exporting data. Which TWO actions should you take to enable and access audit logs? (Choose two.)

Accepted Answer

Access the audit log from the Microsoft 365 compliance portal.. To audit Power BI activities, you must first enable audit logging by turning on the 'Create audit logs for Power BI activities' tenant setting in the Power BI admin portal (option C). Once enabled, you can access the audit logs from the Microsoft 365 compliance portal (option B). Option A is incorrect because Microsoft Defender for Cloud Apps is not the primary location for audit logs; it can integrate but is not required. Option D is incorrect because Power BI does not have an export feature for audit logs to CSV; you can export from the compliance portal. Option E is incorrect because Azure Monitor diagnostic settings are for Azure resources, not for Power BI audit logs.

Answer

Configure Microsoft Defender for Cloud Apps to forward logs to Microsoft Sentinel.

Answer

Use the 'Export' feature in Power BI to export audit logs to a CSV file.

Answer

Set up a diagnostic setting in Azure Monitor to collect Power BI logs.

Question 10

You manage a Power BI tenant. You need to prevent users from sharing reports with external users. Which THREE actions should you take?

Accepted Answer

Create a Microsoft Entra ID conditional access policy to block external users.. Options A, B, and C are correct. Creating a Microsoft Entra ID conditional access policy blocks external users from accessing resources. Disabling 'Publish to web' prevents public embedding of reports. Disabling 'Share content with external users' in the admin portal prevents sharing with external users. Option D is wrong because disabling 'Create app workspaces' does not prevent sharing with external users; it prevents creation of workspaces. Option E is wrong because disabling 'Export to Excel' does not affect sharing.

Answer

Disable 'Create app workspaces' for non-admins.

Answer

Disable 'Export to Excel' for all reports.

Question 11

Which TWO are valid methods to handle null values in Power Query? (Choose two.)

Accepted Answer

Use the 'Fill Down' or 'Fill Up' option to propagate non-null values into null cells.. 'Fill Down' and 'Fill Up' propagate the last non-null value into adjacent null cells. Option C is correct because 'Replace Values' can replace nulls with a default value. Option B is incorrect: 'Remove Blank Rows' removes rows where all cells are blank, not rows with nulls in specific columns. Option D is not a direct method for handling nulls; merging may introduce new data but does not handle existing nulls. Option E is invalid because changing to a non-nullable type causes errors.

Answer

Remove rows that contain null values using the 'Remove Rows' > 'Remove Blank Rows' option.

Answer

Merge the table with another table that has no nulls.

Answer

Change the data type of the column to a non-nullable type.

Question 12

Which are valid ways to create a calculated table in Power BI? (Select all that apply)

Accepted Answer

VALUES(Customer[Country]). To create a calculated table, you need a DAX expression that returns a table object. Options A, C, D, and E all return tables: VALUES returns a single-column table of distinct values; FILTER returns a filtered subset of rows; CALENDARAUTO returns a date range table; SUMMARIZE returns a grouped table with aggregations. Option B, CALCULATE, returns a scalar value, not a table, so it is invalid.

Answer

CALCULATE(SUM(Sales[Amount]), ALL(Sales))

Question 13

You are creating a Power BI report that uses a table named Orders with columns: OrderID, OrderDate, ShipDate, and Status. You need to create a calculated table that contains one row per month with the total number of orders shipped in that month. Which TWO steps should you take?

Accepted Answer

Use SUMMARIZECOLUMNS with 'Date'[Month] and COUNTROWS of Orders. To create a calculated table that shows total orders shipped per month, you can directly group by the month of ShipDate using SUMMARIZECOLUMNS. Since the Orders table already contains a ShipDate column, a separate date table is not required for this aggregation. Option C (creating a date table) is unnecessary here; you can simply extract the month from ShipDate within the grouping. Option D correctly uses SUMMARIZECOLUMNS with 'Date'[Month] and COUNTROWS of Orders. Note: If the 'Date' table is not already present, you would need to create it, but the question asks for steps to create a calculated table that contains one row per month with totals. The most direct step is to use SUMMARIZECOLUMNS with the month column from the Orders table (or a date table if available). However, among the given options, only D is a required step.

Answer

Use CALENDARAUTO in a measure

Answer

Use the GROUPBY function

Answer

Create a date table using CALENDAR or CALENDARAUTO

Answer

Use the VALUES function to get unique months

Question 14

Which TWO of the following are valid methods to share a Power BI report with external users who do not have an internal Microsoft Entra ID account? (Select two.)

Accepted Answer

Deploy the report to Power BI Report Server and configure anonymous access. Deploy the report to Power BI Report Server and configure anonymous access allows external users without Microsoft Entra ID accounts to view the report via a web portal or URL. Option C is correct: Inviting them as guest users in Microsoft Entra ID (B2B) enables external users to access the report through the Power BI service using their existing email address. Option A is wrong: Publishing to public web makes the report publicly accessible to anyone on the internet, not just specific external users. Option D is wrong: Email subscriptions send a static snapshot of the report, not an interactive experience. Option E is wrong: Embedding in SharePoint Online requires the user to have a valid Power BI license and access to the report via the Power BI service, which typically requires internal authentication.

Answer

Publish to public web (Publish to web)

Answer

Send them an email subscription with the report attached

Answer

Embed the report in a SharePoint Online page and share the link

Question 15

Which THREE components must be in place to enable Power BI data sensitivity labels from Microsoft Purview? (Select exactly three.)

Accepted Answer

Power BI admin setting to enable sensitivity labels enabled. Options A, B, and D are correct. To enable Power BI data sensitivity labels from Microsoft Purview, three components are needed: the Power BI admin setting to enable sensitivity labels must be turned on (A), sensitivity labels must be published to users or groups in the Microsoft Purview compliance portal (B), and a Microsoft Purview Information Protection subscription (including Azure Information Protection P1/P2) is required (D). Option C is incorrect because Power BI Premium capacity is not a prerequisite; sensitivity labels work with both Power BI Pro and Premium capacities. Option E is incorrect because a Power BI Pro license is not required for all users; the feature can be used with any license type if the admin enables it and the necessary subscriptions are in place.

Answer

Power BI Premium capacity assigned to the workspace

Answer

Power BI Pro license for all users

Question 16

Which TWO of the following are valid methods to share a Power BI report with external users (outside your organization)? (Choose two.)

Accepted Answer

Invite the external user as a guest in your Microsoft Entra ID (Azure AD) and share the report directly with them.. The correct answers are C and E. Option C: By inviting external users as guests in your Microsoft Entra ID (Azure AD) using Azure AD B2B, you can share Power BI reports directly with them without requiring them to have a Power BI license. Option E: 'Publish to web' creates a public embed code that anyone on the internet can view, making it suitable for sharing with external users. Option A is incorrect because exporting to PDF creates a static file, not an interactive report, and is not a sharing method. Option B is incorrect because external users need to be set up as guests or use publish to web; a direct link alone will not work without proper authentication. Option D is incorrect because embedding in SharePoint Online requires the external user to have access to the SharePoint site, which typically involves additional setup such as guest access.

Answer

Export the report to PDF and email it to the external user.

Answer

Send the external user a direct link to the report via email; they can view it without any additional setup.

Answer

Embed the report in a SharePoint Online page using the Power BI web part.

Question 17

Which THREE of the following are valid methods to enhance the accessibility of a Power BI report? (Choose three.)

Accepted Answer

Provide keyboard navigation support by setting tab order.. Setting tab order in Power BI allows keyboard-only users to navigate through report visuals in a logical sequence, which is a core requirement of WCAG 2.1 success criterion 2.4.3 (Focus Order). Option C is correct because Power BI provides built-in high contrast themes that enhance readability for users with visual impairments. Option E is correct because adding alt text to visuals ensures screen readers can convey the content to visually impaired users. Option D is not considered a valid method for this question; while using a color-blind friendly palette is a good design practice, it is not specifically a method to enhance accessibility in the context of the exam. Option A is incorrect as animations can distract and are not an accessibility feature.

Answer

Add animations to visuals to draw attention.

Answer

Use a color-blind friendly palette.

Question 18

Which TWO actions can you take in Power Query Editor to improve data quality and reduce load time? (Choose two.)

Accepted Answer

Filter out empty rows.. Filtering out empty rows in Power Query Editor directly reduces the number of rows loaded into the data model, which decreases memory usage and improves refresh performance. This action also enhances data quality by removing incomplete records that could cause errors in measures or relationships. The other options either do not reduce load time or may increase it.

Answer

Split columns by delimiter to create more columns.

Answer

Sort the data by a key column.

Answer

Promote headers to use the first row as column names.

Answer

Merge queries to combine data from multiple sources.

Question 19

Which TWO actions can you perform using Power BI Desktop's Query Editor? (Choose two.)

Accepted Answer

Merge two tables based on a common column.. In Power BI Desktop's Query Editor, you can merge two tables based on a common column using the 'Merge Queries' feature (option B) and remove duplicate rows using the 'Remove Duplicates' feature (option D). Creating a relationship between tables (option C) is not performed in Query Editor; it is done in the Model view after loading data. Defining row-level security roles (option A) and creating DAX measures (option E) are also not available in Query Editor — roles are managed in the Modeling tab or Power BI Service, and measures are created in the Report or Data view.

Answer

Define row-level security (RLS) roles.

Answer

Create a relationship between two tables.

Answer

Create a new measure using DAX.

Question 20

A company has a Power BI semantic model that uses DirectQuery to a SQL Server database. The model includes a large fact table with 100 million rows. Users are experiencing slow report performance. Which TWO actions should the developer take to improve query performance?

Accepted Answer

Create indexes on columns used in filters and relationships.. In DirectQuery mode, incremental refresh is not supported (option A is incorrect). Creating indexes on columns used in filters and relationships (option B) speeds up query execution on SQL Server. Removing unused columns from the fact table (option C) reduces the amount of data transferred per query. Hiding columns (option D) does not affect the data retrieved by queries. Adding calculated columns (option E) increases query overhead and degrades performance.

Answer

Configure incremental refresh to limit data retrieved per query.

Answer

Hide columns that are not needed in reports.

Answer

Add calculated columns to precompute aggregations.
