Practice Questions: Use Copilot to summarize the underlying semantic model (PL-300 Exam Prep)

 
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 Copilot to summarize the underlying semantic model

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

1. What is the primary purpose of using Copilot to summarize a semantic model in Power BI?

A. To create new calculated measures automatically
B. To optimize model performance and storage
C. To explain the structure, metrics, and insights of the model using natural language
D. To apply row-level security rules

Correct Answer: C

Explanation:
Copilot’s role is to describe and explain the semantic model in natural language, including tables, relationships, and key measures. It does not create measures, optimize performance, or manage security.

2. Which Power BI component does Copilot analyze when generating a summary?

A. The original data source (SQL, Excel, etc.)
B. The report visuals only
C. The semantic model (dataset)
D. The Power Query transformation steps

Correct Answer: C

Explanation:
Copilot uses the semantic model—tables, relationships, and measures—to generate summaries. It does not inspect Power Query steps or source system schemas directly.

3. A business user wants a quick explanation of what a dataset represents and which metrics are most important. Which feature should you recommend?

A. Analyze in Excel
B. Copilot semantic model summary
C. Performance Analyzer
D. Drill-through pages

Correct Answer: B

Explanation:
Copilot is designed to quickly explain datasets and highlight important metrics using natural language, making it ideal for onboarding or high-level understanding.

4. Which of the following is required in order to use Copilot in Power BI?

A. A Premium capacity or Fabric-enabled environment
B. A DirectQuery data model
C. Python visuals enabled
D. Auto date/time disabled

Correct Answer: A

Explanation:
Copilot requires a Fabric-enabled tenant (Premium or equivalent). The other options are unrelated to Copilot functionality.

5. What type of output does Copilot provide when summarizing a semantic model?

A. DAX expressions
B. SQL queries
C. Natural language descriptions
D. Tabular performance metrics

Correct Answer: C

Explanation:
Copilot responds with natural language explanations, not code or performance diagnostics.

6. Copilot summarizes a dataset but does not show certain tables. What is the most likely reason?

A. The tables are hidden or inaccessible to the user
B. The tables contain calculated columns
C. The dataset uses Import mode
D. The tables are part of a snowflake schema

Correct Answer: A

Explanation:
Copilot respects existing permissions and visibility. If a user doesn’t have access to certain tables, Copilot will not include them in its summary.

7. Which scenario best demonstrates the value of Copilot for identifying patterns and trends?

A. Automatically fixing incorrect relationships
B. Highlighting common business metrics and observed data themes
C. Detecting model circular dependencies
D. Refreshing the dataset on a schedule

Correct Answer: B

Explanation:
Copilot helps identify high-level themes and patterns in the data by summarizing metrics and their business meaning.

8. Which statement about Copilot and semantic models is TRUE?

A. Copilot modifies the data model to improve usability
B. Copilot replaces the need for well-designed measures
C. Copilot explains the existing model without changing it
D. Copilot automatically publishes reports

Correct Answer: C

Explanation:
Copilot is read-only and descriptive. It does not alter models, create content, or replace proper modeling practices.

9. A user wants to understand how sales metrics are calculated but does not know DAX. How can Copilot help?

A. By rewriting all measures in SQL
B. By exporting the dataset to Excel
C. By explaining measures in plain language
D. By disabling advanced calculations

Correct Answer: C

Explanation:
Copilot can translate technical model components into plain language, making it easier for non-technical users to understand metrics.

10. From a PL-300 exam perspective, Copilot is best categorized as which type of feature?

A. Data transformation tool
B. AI-assisted insight and explanation feature
C. Performance tuning feature
D. Security configuration feature

Correct Answer: B

Explanation:
Copilot is an AI-assisted feature focused on insight discovery, explanation, and usability—not transformation, tuning, or security.

Final Exam Tips 🧠

  • Copilot summarizes and explains, it does not build or fix models
  • It works on the semantic model layer
  • Outputs are natural language insights
  • It supports pattern identification and storytelling
  • Always respects permissions and tenant settings
