The simplest and most effective approach is to import the Excel file into Power BI and create a date table for time intelligence. This works because importing the flat Excel sheet into Power BI’s in-memory engine allows you to build a separate, dedicated date table using DAX or the built-in calendar function, which then enables robust time-based calculations like year-to-date revenue or period-over-period comparisons. On the Microsoft Power BI Data Analyst PL-300 exam, this question tests your understanding of when to use import mode versus DirectQuery and the necessity of a date table for time intelligence functions—a common trap is assuming you must split a single sheet into multiple tables or use an external database, but Power BI handles flat data efficiently. Remember the memory tip: “One sheet, one import, one date table” to avoid overcomplicating simple Excel data modeling.
PL-300 Model the data Practice Question
This PL-300 practice question tests your understanding of model the data. 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.
You are developing a Power BI report for a sales team. The data source is an Excel file with a single sheet containing columns: Date, Salesperson, Product, Units Sold, Revenue. The file is updated weekly. You need to model the data to allow analysis of revenue by salesperson and product over time. What is the simplest and most effective approach?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Import the Excel file into Power BI and create a date table for time intelligence.
Option A is correct because importing the Excel file and creating a date table allows for time-based analysis with minimal effort. Option B is wrong because using DirectQuery on an Excel file is not supported. Option C is wrong because splitting into multiple tables is unnecessary for a single sheet. Option D is wrong because Power BI can handle the data without an external database.
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.
✗
Load the data into a SQL Server database first, then import from there.
Why it's wrong here
Adds unnecessary steps and infrastructure.
✓
Import the Excel file into Power BI and create a date table for time intelligence.
Why this is correct
This is straightforward and enables time-based analysis.

Read the scenario before looking for a memorised answer.
✗
Use DirectQuery on the Excel file to avoid importing.
Why it's wrong here
DirectQuery is not supported for Excel files.
✗
Split the Excel data into separate dimension and fact tables in Power Query.
Why it's wrong here
Unnecessary complexity for a simple dataset.
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.
