PL-300 Prepare the data Practice Question
This PL-300 practice question tests your understanding of prepare 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 importing data from an Excel workbook that has multiple worksheets. You only need data from the 'Sales' worksheet. When you connect via Power Query, all worksheets appear in the Navigator. What should you do to load only the 'Sales' worksheet?

Correct answer & explanation
✓
Select the 'Sales' worksheet in Navigator and click 'Load'
In Power Query, the Navigator pane allows you to select specific worksheets or tables to load. Selecting the 'Sales' worksheet and clicking 'Load' imports only that data into your data model, avoiding unnecessary data. This is the most efficient method because it directly targets the required worksheet without extra steps.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think they need to use 'Transform Data' to filter or select specific data, but the Navigator itself provides the selection capability, and 'Load' directly imports the chosen data without requiring transformation first.
Detailed technical explanation
How to think about this question
Under the hood, Power Query uses the M language to define data sources and transformations. When you select a specific worksheet in Navigator and click 'Load', Power Query generates a query that references only that worksheet's data, using the Excel.Workbook function with the appropriate sheet index or name. This avoids loading other worksheets into memory, optimizing performance and reducing model size. In real-world scenarios, this is critical when dealing with large workbooks containing many sheets, as loading unnecessary data can slow down refresh times and increase storage.
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.
TExam Day Tips
- 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.
