Official PL-300 Study Guide, PL-300 Question Explanations

The software is designed for use on a Windows computer. This software helps hopefuls improve their performance on subsequent attempts by recording and analyzing Microsoft Power BI Data Analyst (PL-300) exam results. Like the actual Microsoft PL-300 Certification Exam, Microsoft Power BI Data Analyst (PL-300) practice exam software has a certain number of questions and allocated time to answer.

Microsoft Power BI Data Analyst Sample Questions (Q125-Q130):

NEW QUESTION # 125
You have a Power BI model that contains two tables named Population and Date.
The Population table contains two columns named PopulationAmount and DateKey.
DateKey contains date values that represent the first day of a year and are used to create a many-to-one relationship with the Date table.
The Power BI model contains two measures that have the following definitions.
Total Population = Sum('Population'[PopulationAmount])
2023 Population = CALCULATE([Total Population], 'Date'[Year] = 2023)
You create a table visual that displays Date[Year] and [2023 Population].
What will the table visual show?

A. one row per year that contains the same value repeated for each year
B. a single row for the year 2023 that contains the related population value
C. one row per date that contains the population value for the corresponding year repeated in each row
D. one row per year that contains blank values for every year except 2023

Answer: A

NEW QUESTION # 126
You need to create a Power BI report. The first page or the report must contain the following two views:
* Sales By Postal Code
* Sales by Month
Both views must display a slicer to select a value for a field named Chain.
The Sales By Postal Code view must display a map visual as shown in the following exhibit.

Answer:

Explanation:

Explanation:

The key constraint is to create a Power BI report. The first page or the report must contain the following two views: * Sales By Postal Code * Sales by Month Both views must display. The completed mapping shown in the answer area is correct. The other visual or configuration choices encode a different task, lose the required interaction, or fail one of the stated display constraints. A sound report design pairs the user task with the visual ' s strengths, then configures fields and interactions so selections, drill actions, and filtering behave exactly as the scenario requires. The current skills outline describes this competency as " Apply slicing and filtering " .

NEW QUESTION # 127
What should you create to meet the reporting requirements of the sales department?

A. A calculated column: IF(ISBLANK(Sales[sales_amount]), 0, Sales[sales_amount] )
B. A calculated column: ABS(Sales[sales_amount])
C. A measure: SUM(Sales[sales_amount])
D. A measure: SUMX(FILTER(Sales, Sales[sales_amount] > 0), Sales[sales_amount])

Answer: C

Explanation:
The relationship must carry filters from the descriptive table to the transaction table through matching keys.
Bidirectional filtering is reserved for a demonstrated need because it can introduce multiple active paths. The answer resolves to B (A measure: SUM(Sales[sales_amount])). What determines the answer is the need to N NO: 254 What should you create to meet the reporting requirements of the sales department. The opposite cardinality or unnecessary bidirectional filtering can duplicate results, block propagation, or create ambiguity rather than solve the stated model path. This rationale is anchored to the PL-300 objective " Define a relationship ' s cardinality and cross-filter direction " .

NEW QUESTION # 128
Drag and Drop Question
You create a data model in Power BI.
Report developers and users provide feedback that the data model is too complex.
The model contains the following tables.

The model has the following relationships:
- There is a one-to-one relationship between Sales_Region and
Region_Manager.
- There are more records in Manager than in Region_Manager, but every
record in Region_Manager has a corresponding record in Manager.
- There are more records in Sales_Manager than in Sales_Region, but
every record in Sales_Region has a corresponding record in
Sales_Manager.
You need to denormalize the model into a single table. Only managers who are associated to a sales region must be included in the reports.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.
