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.
Refer to the exhibit. The Power BI admin portal shows capacity usage. The Sales workspace is on Premium capacity and the Marketing workspace is on Shared capacity. The admin notices that the Sales dataset refresh takes 45 minutes, and the Marketing dataset refresh takes 10 minutes. Users complain that during the Sales dataset refresh, the Marketing report becomes slow. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
The Marketing workspace should be moved to Premium capacity to avoid contention
Why wrong: Moving Marketing to Premium would not solve the problem because the contention is on the shared node where Sales is also running. Premium capacity is isolated, so Marketing on Premium would not be affected by Sales on shared.
B
The Sales dataset is too large and consumes Premium capacity resources, leaving no resources for Marketing
Why wrong: The Sales dataset refresh does consume Premium resources, but those are separate from shared capacity. The issue is that both workspaces are actually on the same shared node, not that Sales consumes Premium resources.
C
Both workspaces are on the same shared capacity node, and the Sales dataset refresh consumes node resources, slowing Marketing
Correct. Both workspaces share the same shared capacity node. The Sales dataset refresh consumes node resources, slowing Marketing.
D
The Marketing dataset requires a Pro license, which is not assigned
Why wrong: Licensing is not the cause. The slow performance is due to resource contention on the shared node, not a missing Pro license.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Both workspaces are on the same shared capacity node, and the Sales dataset refresh consumes node resources, slowing Marketing
Option C is correct. The Power BI admin portal indicates that both workspaces are consuming resources from the same shared capacity node, even though the Sales workspace is designated as Premium. This could be due to a configuration error or because the Sales workspace is using a Premium Per User (PPU) license that still utilizes shared capacity for dataset refreshes. When the Sales dataset refreshes, it consumes CPU and memory on the shared node, causing contention and slowing the Marketing report. Option A is incorrect because moving Marketing to Premium would not resolve contention on the shared node; Premium capacity is isolated. Option B is incorrect because although the Sales dataset is large, it is not consuming Premium resources that affect Marketing; the contention is on the shared node. Option D is incorrect because the slowdown is due to resource contention, not licensing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Both workspaces are on the same shared capacity node, and the Sales dataset refresh consumes node resources, slowing Marketing
Why this is correct
Correct. Both workspaces share the same shared capacity node. The Sales dataset refresh consumes node resources, slowing Marketing.

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.
