The answer is a Matrix visual with years as columns, quarters as rows, and a DAX measure for year-over-year growth. This configuration is correct because the Matrix visual’s cross-tabulation structure naturally supports comparing quarterly revenue across multiple years, while a custom DAX measure like (Current Year Revenue - Previous Year Revenue) / Previous Year Revenue calculates the exact growth percentage for each quarter. On the PL-900 exam, this tests your understanding of how Power BI visuals map to specific analytical needs—here, the need to display power bi year over year growth by quarter matrix visual in a clear, tabular format. A common trap is choosing a line chart or clustered bar chart, which can show trends but lack the precise per-quarter, per-year comparison that the Matrix provides. Memory tip: think “Matrix = Multi-Year Grid” for direct quarterly comparisons.
PL-900 Demonstrate the capabilities of Power BI Practice Question
This PL-900 practice question tests your understanding of demonstrate the capabilities of power bi. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 financial analyst creates a Power BI report to compare quarterly revenue across years. The data has a 'Date' column and a 'Revenue' column. The analyst wants to display year-over-year growth for each quarter. Which visual and configuration would best achieve this?

Correct answer & explanation
✓
Matrix visual with years as columns, quarters as rows, and a measure for YoY growth
Option B is correct because a Matrix visual allows you to place years as columns and quarters as rows, then define a DAX measure for year-over-year (YoY) growth (e.g., (Current Year Revenue - Previous Year Revenue) / Previous Year Revenue). This directly compares each quarter’s revenue across years in a structured, tabular format, which is the most effective way to display YoY growth for each quarter.
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.
✗
Line chart with date hierarchy and revenue, adding year-over-year trend line
Why it's wrong here
Trend line shows growth over time but not per-quarter comparison.
✓
Matrix visual with years as columns, quarters as rows, and a measure for YoY growth
Why this is correct
Matrix allows side-by-side comparison and custom measures.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Stacked bar chart with quarters on axis and revenue as values, using year as legend
Why it's wrong here
Shows composition, not growth rate.
✗
Scatter plot with revenue on both axes and date as detail
Why it's wrong here
Scatter plot is not suitable for this comparison.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose a chart option (like a line chart with trend lines) thinking it visually shows growth, but the question specifically asks for displaying year-over-year growth for each quarter, which requires a tabular or matrix format to show exact percentage changes per quarter across years.

Command / output trap
Trend line shows growth over time but not per-quarter comparison.
Detailed technical explanation
How to think about this question
In Power BI, a Matrix visual supports conditional formatting and custom DAX measures like CALCULATE(SUM(Revenue), SAMEPERIODLASTYEAR('Date'[Date])) to compute prior-year values. The YoY growth measure can be formatted as a percentage, and the Matrix can display both the raw revenue and the growth rate in the same cell using a custom measure. This approach is common in financial reporting where precise, tabular comparisons are required, and it avoids the visual clutter of charts when exact numbers are needed.

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.
