The answer is SUMMARIZE(Sales, Sales[ProductID], "Total", SUM(Sales[Amount])) and CALENDARAUTO(). Both are valid ways to create a calculated table in Power BI with DAX because each returns a table object that can be assigned directly to a new table in the model. SUMMARIZE groups data by specified columns and adds a calculated aggregation column, while CALENDARAUTO generates a contiguous date table automatically from the model’s date columns. On the PL-300 exam, this tests your understanding that calculated tables are created using DAX functions that output tables—not measures or calculated columns. A common trap is confusing SUMMARIZE with ADDCOLUMNS or thinking CALENDARAUTO requires manual date range arguments. Remember: if a DAX function returns a table, it can define a calculated table. For the exam, think “table in, table out”—any function that outputs a table is a valid constructor.
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 are valid ways to create a calculated table in Power BI?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
CALENDARAUTO()
Option D is correct because `CALENDARAUTO()` is a dedicated DAX function that automatically generates a single-column calculated table containing a contiguous range of dates based on the data model's date columns. This is a standard and valid method for creating a calculated table in Power BI, commonly used for time intelligence calculations.
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.
✗
VALUES(Customer[Country])
Why it's wrong here
VALUES returns a table but is not a calculated table creation syntax; it's a function used in measures or calculated columns.
✗
CALCULATE(SUM(Sales[Amount]), ALL(Sales))
Why it's wrong here
CALCULATE returns a scalar value, not a table.
✗
FILTER(Products, Products[Color] = "Red")
Why it's wrong here
FILTER returns a table but must be used in a context like a calculated table definition, not standalone.
✓
CALENDARAUTO()
Why this is correct
CALENDARAUTO() returns a table of dates.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse table functions (like `VALUES`, `FILTER`, and `SUMMARIZE`) that return tables but are not valid standalone calculated table definitions, with the specific requirement that a calculated table must be created using a DAX expression that returns a table object and is assigned directly in the 'Calculated table' dialog.
Detailed technical explanation
How to think about this question
Calculated tables in Power BI are defined using DAX expressions that return a table object, and they are evaluated once when the model is refreshed, storing the result as a physical table. `CALENDARAUTO()` scans all date columns in the model to determine the minimum and maximum dates, then expands the range to cover full years, which is useful for creating a date dimension without manual date boundaries. In contrast, `SUMMARIZE` (option E) is a valid table function that groups data and can create a calculated table, but it is often used with `ADDCOLUMNS` to avoid implicit measure evaluation issues.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO of the following are valid ways to create a calculated table in Power BI? (Select TWO.)
easy
✓ A.Use the DAX expression with the SUMMARIZE function.
B.Use the Merge Queries feature in Power Query Editor.
C.Use the Split Column feature in Power Query Editor.
✓ D.Use the DAX expression with the ADDCOLUMNS function.
E.Use the Group By feature in a matrix visual.
Why A: 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.
Variation 2. Which TWO of the following are valid ways to create a calculated table in Power BI?
Why C: Option C is correct because SUMMARIZE is a DAX function that creates a calculated table by grouping rows from a table (Sales) and adding a new column with an aggregate expression (SUM(Sales[Amount])). Option E is correct because CALENDARAUTO() returns a single-column table of dates, which is a valid calculated table definition in Power BI.
Variation 3. Which TWO of the following are valid ways to create a calculated table in Power BI? (Select two.)
easy
✓ A.Using the CALENDAR function to generate a date table.
✓ B.Using DAX expressions like SUMMARIZE or ADDCOLUMNS.
C.Using the 'New Table' button under the 'Modeling' tab and writing a Power Query expression.
D.Using M language in Power Query Editor.
E.By right-clicking a table in the Fields pane and selecting 'New calculated table'.
Why A: Option A is correct because you can use DAX expressions like SUMMARIZE. Option D is correct because you can use CALENDAR to create a date table. Option B is wrong because calculated tables are defined in DAX, not M. Option C is wrong because Power Query creates tables, but not calculated tables. Option E is wrong because calculated tables are not created in the model view right-click.
