The correct answer is to create a DLP policy in Microsoft Purview that detects credit card numbers in Power BI and set the action to block export. This works because Microsoft Purview Data Loss Prevention policies can scan Power BI datasets and reports for sensitive info types, such as credit card numbers, and enforce protective actions like blocking data export directly at the content level. On the PL-300 exam, this question tests your understanding of how DLP integrates with Power BI to prevent data leakage, often appearing as a distractor against sensitivity labels, row-level security, or tenant settings—none of which can dynamically block exports based on specific data patterns. A common trap is assuming a sensitivity label alone stops exports, but labels only classify and apply visual markings, not block actions. Remember the mnemonic: DLP detects, labels label, RLS restricts rows, and tenant settings are a blunt tool—only DLP can block exports based on content like credit card numbers.
PL-300 Manage and secure Power BI Practice Question
This PL-300 practice question tests your understanding of manage and secure power bi. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization uses Power BI and has deployed Microsoft Purview Data Loss Prevention (DLP) policies. You want to prevent users from exporting data from Power BI reports that contain credit card numbers. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a DLP policy in Microsoft Purview that detects credit card numbers in Power BI and set the action to block export.
Option D is correct because DLP policies in Power BI can be applied to datasets and reports, and they can block export of data that matches sensitive info types like credit card numbers. Option A is wrong because sensitivity labels alone do not block export. Option B is wrong because RLS restricts data visibility, not export. Option C is wrong because tenant settings control general export capabilities but not based on content.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure row-level security (RLS) to hide the credit card column from users.
Why it's wrong here
RLS hides data but does not prevent export of other data.
✓
Create a DLP policy in Microsoft Purview that detects credit card numbers in Power BI and set the action to block export.
Why this is correct
DLP policies can block export when sensitive data is detected.
Related concept
Read the scenario before looking for a memorised answer.
✗
Apply a Microsoft Purview sensitivity label 'Highly Confidential' to the dataset and configure the label to prevent export.
Why it's wrong here
Sensitivity labels mark content but do not block export unless combined with DLP.
✗
Disable the 'Export to Excel' and 'Export to CSV' settings in the Power BI admin portal.
Why it's wrong here
This disables export for all users, which is too broad.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
