What does scalability mean in Power BI?

Scalability means the ability of a Power BI report or dashboard to handle more data or more users without slowing down or breaking.

Why is optimization important for scalability?

Optimization improves how fast and efficiently Power BI processes data, so it can handle bigger datasets and more users smoothly.

Name one common optimization technique in Power BI.

One common technique is reducing the number of columns and rows loaded into the model to keep it light and fast.

How does a slow report affect scalability?

A slow report can’t handle many users or large data well, causing delays and poor experience as data or users grow.

What role does DAX optimization play in scalability?

Optimizing DAX formulas makes calculations faster, so reports respond quickly even with more data or users.

What happens if a Power BI report is not optimized?

A It may become slow and hard to use with more data.

B It will automatically handle more users better.

C It will reduce data size by itself.

D It will improve visuals without changes.

Without optimization, reports slow down as data or users increase, hurting scalability.

Which of these helps improve scalability in Power BI?

A Loading all data without filtering.

B Adding many visuals without purpose.

C Using efficient DAX formulas.

D Ignoring data model relationships.

Efficient DAX formulas speed up calculations, helping reports scale better.

Scalability means:

A Reports work well only with small data.

B Reports can handle more data and users smoothly.

C Reports never need updates.

D Reports use more memory over time.

Scalability is about handling growth in data and users without problems.

Which practice does NOT help scalability?

A Loading all historical data without filters.

B Optimizing DAX calculations.

C Reducing unnecessary columns.

D Using aggregations for large data.

Loading all data without filtering can slow down reports and hurt scalability.

What is a sign that a Power BI report needs optimization?

A It uses simple DAX formulas.

B It loads instantly with large data.

C It has very few visuals.

D It slows down when many users access it.

Slowing down with more users shows the report needs optimization for scalability.

Explain in simple terms why optimization helps Power BI reports handle more data and users.

Think about how a clean and organized workspace helps you work faster.
