Question 224 of 966

Visualize and analyze the data →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the schema is missing a separate date table marked as a date table. Time intelligence functions in Power BI, such as TOTALYTD or SAMEPERIODLASTYEAR, require a dedicated date table with a continuous, unique date range that has been explicitly marked in the table’s properties; without this, the engine cannot resolve the necessary calendar hierarchy for calculations like period-over-period comparisons. On the Microsoft Power BI Data Analyst PL-300 exam, this concept frequently appears in schema review questions where a single Date column in a fact table is used for time intelligence, which is a common trap—candidates often overlook that a standalone date table must be present and marked. A reliable memory tip is “One date column is not enough; you need a date table marked as such.”

PL-300 Visualize and analyze the data Practice Question

This PL-300 practice question tests your understanding of visualize and analyze the data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

A
There is no separate date table marked as a date table.
Time intelligence requires a date table.
B
The version should be 2.0.
Why wrong: Version is not relevant.
C
The Amount column should be a decimal.
Why wrong: int64 is fine.
D
The data type for Date should be date instead of dateTime.
Why wrong: dateTime is acceptable.

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

✓

There is no separate date table marked as a date table.

Option D is correct because a separate date table is needed for time intelligence functions to work properly. Option A is wrong because data types are specified. Option B is wrong because the schema is valid JSON. Option C is wrong because there is no indication of an issue with columns.

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.
