- A
Create a separate date table with a continuous range of dates.
A proper date table is needed to create a date hierarchy and support time intelligence.
- B
Enable auto date/time in Power BI Desktop.
Why wrong: Auto date/time creates hidden date tables but may not support custom hierarchies.
- C
Sort the Month column by MonthNumber to ensure proper order.
Why wrong: Sorting by month number is a good practice but not required for creating a date hierarchy.
- D
Mark the date table as a date table in Power BI Desktop.
Marking the date table as a date table enables time intelligence functions and hierarchy creation.
- E
Add calculated columns for Year, Quarter, and Month to the date table.
Why wrong: Calculated columns alone do not create a hierarchy; you need to create a hierarchy in the model.
Quick Answer
The two required actions are marking the date table as a date table in Power BI Desktop and creating a date table with a continuous range of dates. Marking a date table as a date table is essential because it tells Power BI that the table contains valid date values, enabling time intelligence functions and allowing you to build a proper date hierarchy for drill-downs like Year, Quarter, and Month. Creating a date table with a continuous range ensures that every period is represented, even if the source data has gaps, which is critical for accurate time-based analysis. On the PL-300 exam, this question tests your understanding of how to set up custom date tables versus relying on the auto date/time feature, which creates hidden hierarchies but lacks flexibility for custom requirements. A common trap is assuming calculated columns alone can create a hierarchy, but they cannot—you need a marked date table. Memory tip: “Mark it, then drill it”—always mark your date table first to unlock hierarchy and time intelligence.
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 preparing data for a Power BI report. The source data has a column 'OrderDate' with date values. You need to create a date hierarchy for drill-down (Year, Quarter, Month). Which TWO actions are required?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a separate date table with a continuous range of dates.
Options B and D are correct. You need to mark a date table as a date table to enable time intelligence and create a date hierarchy. Creating a date table with a continuous range ensures all periods are represented. Option A is wrong because auto date/time creates hidden hierarchies but may not be sufficient for custom requirements. Option C is wrong because calculated columns do not create a hierarchy. Option E is wrong because sorting by month number is useful but not required for a hierarchy.
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
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.
