Data Source Settings and Privacy: 10 practice questions
10 free PL-300 practice questions on Data Source Settings and Privacy, with an explanation for every answer. Untimed. The full mock exam and the timed version are in the app.

Question 1 of 10
Which Power BI Desktop command opens the list of existing source connections for maintenance?
- AClose and Apply
- BData source settings
- CNavigator
- DChange Source for the selected connection
Show the answer
Data source settings exposes existing connections and their maintenance actions; Change Source is one action inside that window, Navigator selects source objects, and Close and Apply commits Power Query changes.

Question 2 of 10
Which SQL Server sign-in choice fits credentials issued directly by the database administrator?
- ADatabase
- BMicrosoft account
- CWindows
- DConnect live
Show the answer
Database authentication accepts the database system's own credentials; Windows and Microsoft account use different identities, while Connect live is a connectivity choice rather than authentication.

Question 3 of 10
Which action is used to change the saved privacy-level setting for a selected source?
- AEdit permissions
- BClear Permissions
- CTransform Data
- DChange Source
Show the answer
Privacy belongs to the selected source's saved permission configuration; source-location changes, permission removal, and data transformation serve different purposes.

Question 4 of 10
What should you do in Data source settings after a connected file moves to another folder?
- AOpen Navigator and select a different table
- BChoose Change Source and update the file path
- CChoose Clear Permissions and retain the old path
- DChoose Edit permissions and replace the credential
Show the answer
A moved file changes connection location, so Change Source is the relevant maintenance action; credentials, saved permissions, and object selection do not replace the obsolete path.

Question 5 of 10
Which Query Settings control provides an alternative route for updating relational connection details?
- AThe credential tab in SQL Server
- BThe Close and Apply button in the report view
- CThe settings icon next to Source
- DThe Navigator check box next to a table
Show the answer
The Source step's settings control reopens the connection details for the selected query; Navigator, authentication tabs, and Close and Apply address other stages.

Question 6 of 10
Which maintenance action removes saved permission information for an existing connection?
- AChange Source
- BEdit permissions
- CClear Permissions
- DClose and Apply
Show the answer
Clearing permissions removes the saved access information so the connection can request it again; editing, relocating, and applying changes have narrower purposes.

Question 7 of 10
After updating server and database details from Power Query, what completes the settings change?
- AConfirm the dialog, then select Close and Apply
- BOpen Navigator, then select Transform Data
- CClear permissions, then retain the former server
- DChange the credential, then cancel the dialog
Show the answer
The connection details are confirmed in their dialog and then committed through Close and Apply; the other sequences discard or redirect the requested update.

Question 8 of 10
A connected workbook moved to a new folder, and the replacement file also renamed two columns that report visuals use. Which plan repairs the report?
- AEdit permissions and enter the credential again, because the workbook now sits in another folder
- BChange Source for the new path, because a refresh maps the renamed columns back automatically
- CChange Source for the new path, then repair the steps and fields built on the old column names
- DClear Permissions so the connection asks for the file again and rebuilds its column names
Show the answer
Two things changed, so two repairs are needed. Change Source fixes the location, but queries, relationships, calculations, and report fields still point at the old column names, and renamed source columns break that dependent logic until it is updated.

Question 9 of 10
A security policy requires a new password for a SQL Server connection that uses a database-issued identity. Which update fits?
- AEdit permissions and switch the identity to Connect live
- BChange Source and replace the database with a workbook
- CClear Permissions and keep using the expired password
- DEdit permissions and keep Database as the credential type
Show the answer
A password rotation changes saved access information, while the database-issued identity still maps to Database authentication; source replacement and connectivity modes solve different problems.

Question 10 of 10
A workbook of confidential employee reviews must be merged with an organizational SQL Server table. Privacy levels are enforced, and the review data must never reach that database. Which privacy level fits the workbook?
- APrivate, which keeps the workbook data from folding into the other source
- BNone, which leaves the workbook unclassified so the merge can proceed
- CPublic, which lets the workbook data fold into any other data source
- DOrganizational, which lets the workbook data fold into that SQL Server source
Show the answer
Privacy levels are isolation settings, and Private is the one reserved for sensitive or confidential content. Data from a private source cannot fold into any other source, not even another private one, and that refusal is what stops the review rows from travelling to the SQL Server database during the merge. This protection depends on enforcement: if the file ignores privacy levels, Power Query no longer blocks the transfer.
