PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze 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.
Which TWO of the following are valid ways to create a calculated table in Power BI? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the DAX expression with the SUMMARIZE function.
Option A is correct because the SUMMARIZE function in DAX creates a calculated table by grouping data from one or more tables, returning a new table with distinct combinations of the specified columns. This is a standard way to generate a calculated table in Power BI for further analysis or modeling.
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.
✓
Use the DAX expression with the SUMMARIZE function.
Why this is correct
SUMMARIZE can create a calculated table.

✗
Use the Merge Queries feature in Power Query Editor.
Why it's wrong here
Merge Queries creates a new query, not a calculated table.
✗
Use the Split Column feature in Power Query Editor.
Why it's wrong here
Split Column splits a column, not creates a table.
✓
Use the DAX expression with the ADDCOLUMNS function.
Why this is correct
ADDCOLUMNS can create a calculated table.
Related concept

✗
Use the Group By feature in a matrix visual.
Why it's wrong here
Group By in visuals does not create a table.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Power Query transformations (like Merge Queries or Split Column) with DAX-based calculated tables, or mistake visual-level grouping for a data model object, leading them to select B, C, or E as valid methods.
Detailed technical explanation
How to think about this question
Calculated tables in Power BI are created using DAX expressions that return a table, such as SUMMARIZE or ADDCOLUMNS, and are evaluated at model refresh time. Unlike Power Query transformations, calculated tables are stored in the in-memory columnar engine (VertiPaq) and can be used in relationships, measures, and other DAX expressions. A subtle behavior: SUMMARIZE can also add new columns via an optional expression argument, but it is primarily used for grouping, while ADDCOLUMNS adds calculated columns to an existing table without grouping.
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.
