Question 53 of 966

Model the data →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct approach is to create a date table using the CALENDAR function with a continuous date range covering all possible dates, then use Mark as Date Table in the model view. This method is essential because DAX time intelligence functions like TOTALYTD and SAMEPERIODLASTYEAR require a contiguous, uninterrupted date range to calculate period-over-period comparisons correctly; a table built only from existing order dates would contain gaps, breaking these calculations. On the PL-300 exam, this question tests your understanding of how to properly structure a date table for time intelligence, often appearing as a scenario where you must choose between a continuous calendar and a subset of dates. A common trap is assuming that distinct order dates are sufficient, but the exam expects you to recognize that time intelligence demands a complete date spine. Remember the memory tip: "No gaps, no gaps—time intelligence snaps."

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 designing a data model for a sales analysis report. The source data includes a table named 'Sales' with columns: OrderDate, CustomerID, ProductID, Quantity, and SalesAmount. You need to create a date table to support time intelligence calculations. Which approach should you use?

A
Create a date table using CALENDAR function with a continuous date range covering all possible dates, then use Mark as Date Table in the model view
This ensures a continuous date range and proper recognition by time intelligence functions.
B
Use the CALENDARAUTO function to automatically generate dates and rely on auto date/time
Why wrong: Auto date/time may not be sufficient for complex time intelligence and is not recommended for large models.
C
Use the DISTINCT function on Sales[OrderDate] to create a date table
Why wrong: This creates a list of only order dates, not a continuous date range.
D
Create a date table using CALENDAR function with start date = MIN(Sales[OrderDate]) and end date = MAX(Sales[OrderDate])
Why wrong: This may miss dates outside the sales range and may not be continuous if there are gaps.

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 date table using CALENDAR function with a continuous date range covering all possible dates, then use Mark as Date Table in the model view

Option C is correct because creating a separate date table with a continuous date range and marking it as a date table using the Mark as Date Table feature allows DAX time intelligence functions like TOTALYTD and SAMEPERIODLASTYEAR to work correctly. Option A is wrong because generating dates from the earliest to latest order dates may miss dates with no sales, causing gaps. Option B is wrong because using only distinct order dates from Sales table does not create a continuous date range. Option D is wrong because using DAX CALENDARAUTO without marking as date table may not be recognized by time intelligence functions.

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.
