The correct answer is to implement row-level security (RLS) to limit the data loaded per user. RLS reduces memory pressure on Power BI Premium capacity by filtering data at query time, so each user’s session loads only the rows they are permitted to see, rather than the entire dataset into memory. This directly addresses capacity overload by lowering the per-query memory footprint, especially in environments with large fact tables. On the Microsoft PL-300 exam, this question tests your understanding of capacity management versus dataset optimization—a common trap is confusing RLS with security only, when its primary benefit here is memory reduction. Remember that increasing refresh frequency or enabling the large dataset storage format actually increases memory consumption, while moving to shared capacity shifts but doesn’t solve the bottleneck. Memory tip: RLS trims the load, so your Premium node won’t explode.
PL-300 Manage and secure Power BI Practice Question
This PL-300 practice question tests your understanding of manage and secure power bi. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A company uses Power BI Premium with a capacity-based license. The capacity is frequently reaching its memory limit, causing reports to be evicted. You need to reduce memory pressure on the capacity. What should you do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement row-level security (RLS) to limit data loaded per user.
Option D is correct. Implementing RLS can reduce the amount of data loaded into memory for each user, thus reducing memory pressure. Option A is wrong because increasing the refresh frequency can increase memory usage. Option B is wrong because enabling 'Large dataset storage format' increases memory usage. Option C is wrong because moving datasets to a shared capacity does not help if the problem is capacity overload.
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.
✗
Enable the 'Large dataset storage format' for all datasets.
Why it's wrong here
This format uses more memory.
✗
Move all datasets to a shared capacity.
Why it's wrong here
Shared capacity has lower limits and may cause more evictions.
✗
Increase the scheduled refresh frequency to every hour.
Why it's wrong here
More frequent refreshes can increase memory usage.
✓
Implement row-level security (RLS) to limit data loaded per user.
Why this is correct
RLS can reduce memory footprint by loading only relevant data.

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.

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.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. You are managing a Power BI deployment that uses Premium capacity. Users report that reports are loading slowly during peak hours. You need to identify whether the capacity is being overused. Which metric should you monitor?
hard
A.Memory usage percentage.
B.Total dataset size in the workspace.
✓ C.CPU high time percentage.
D.Average query execution time.
Why C: Option C is correct because CPU over-utilization is a key indicator of capacity stress in Premium. The 'CPU high' metric directly reflects processing load. Option A is wrong because query execution time is a result, not a direct capacity metric. Option B is wrong because memory usage is important but CPU is more directly tied to responsiveness. Option D is wrong because dataset size is a design factor, not a real-time capacity metric.
