This post is a part of the PL-300: Microsoft Power BI Data Analyst Exam Prep Hub; and this topic falls under these sections:
Visualize and analyze the data (25–30%)
--> Identify patterns and trends
--> Use the Analyze Feature in Power BI
Below are 10 practice questions (with answers and explanations) for this topic of the exam.
There are also 2 practice tests for the PL-300 exam with 60 questions each (with answers) available on the hub.
Practice Questions
Question 1
A business user wants to understand why total sales increased from one month to the next without writing DAX. Which Analyze feature should they use?
A. Key influencers
B. Decomposition tree
C. Explain the increase
D. Quick insights
Correct Answer: C
Explanation:
Explain the increase automatically analyzes contributing factors behind a change between two data points, such as month-over-month sales growth.
Question 2
Which requirement must be met to use anomaly detection in Power BI?
A. The data must include calculated columns
B. The visual must use a time-based axis
C. The dataset must be in Import mode
D. The report must be published to the service
Correct Answer: B
Explanation:
Anomaly detection requires a continuous time-based axis (such as date or time) to identify unexpected spikes or dips.
Question 3
A report author wants to identify which customer attributes most strongly influence high revenue. Which visual should they use?
A. Decomposition tree
B. Analyze insights
C. Key influencers
D. Explain the decrease
Correct Answer: C
Explanation:
The Key influencers visual uses machine learning to determine which factors most strongly influence a selected metric.
Question 4
Which Analyze feature allows users to manually or automatically split a measure across multiple dimensions?
A. Explain the increase
B. Decomposition tree
C. Analyze insights
D. Quick insights
Correct Answer: B
Explanation:
The Decomposition tree allows step-by-step breakdown of a measure using either manual selections or AI-driven splits.
Question 5
A user right-clicks a bar in a column chart and selects Analyze → Explain the decrease. What does Power BI generate?
A. A new calculated measure
B. A static tooltip
C. AI-generated visuals explaining contributing factors
D. A drill-through page
Correct Answer: C
Explanation:
Power BI generates read-only AI-generated visuals that explain what contributed to the decrease.
Question 6
Which statement about Analyze insights is TRUE?
A. It modifies the data model
B. It only works on tables
C. It provides automatic pattern detection within a visual
D. It requires DAX measures
Correct Answer: C
Explanation:
Analyze insights automatically detect patterns, trends, outliers, and correlations within supported visuals.
Question 7
A dataset is published to the Power BI Service. A user wants Power BI to automatically scan the entire dataset for trends and outliers. Which feature should they use?
A. Analyze insights
B. Key influencers
C. Decomposition tree
D. Quick insights
Correct Answer: D
Explanation:
Quick insights run in the Power BI Service and analyze the entire dataset, not just individual visuals.
Question 8
Which Analyze feature is best suited for explaining why a KPI changed between two specific points in time?
A. Key influencers
B. Decomposition tree
C. Explain the increase/decrease
D. Analyze insights
Correct Answer: C
Explanation:
Explain the increase/decrease is designed specifically to analyze changes between two values.
Question 9
Why might Analyze features produce poor or misleading results?
A. The report uses DirectQuery
B. Relationships and data types are poorly designed
C. The dataset contains too many measures
D. Visual interactions are disabled
Correct Answer: B
Explanation:
Analyze features rely heavily on clean data, correct relationships, and appropriate data types to generate accurate insights.
Question 10
Which statement best describes the role of Analyze features in Power BI?
A. They replace the need for DAX
B. They permanently alter report visuals
C. They assist with exploratory analysis and insight discovery
D. They are required for all Power BI reports
Correct Answer: C
Explanation:
Analyze features are designed for exploratory analysis and pattern discovery, not as replacements for modeling or DAX.
PL-300 Exam Tip
Expect scenario-based questions that test:
- Which Analyze feature to use
- Feature limitations and requirements
- Differences between similar tools (Key influencers vs Decomposition tree, Analyze insights vs Quick insights)
