Q&A


D.

key influencers





D.
  

key influencers



Explanation:
The key influencers visual is a great choice if you want to:
See which factors affect the metric being analyzed.
Contrast the relative importance of these factors. For example, do short-term contracts
affect churn more than long-term contracts?
Note: The key influencers visual helps you understand the factors that drive a metric you're
interested in. It analyzes your data, ranks the factors that matter, and displays them as key
influencers. For example, suppose you want to figure out what influences employee
turnover, which is also known as churn. One factor might be employment contract length,
and another factor might be commute time.

Explanation:
General availability of sensitivity labels in Power BI.
Microsoft Information Protection sensitivity labels provide a simple way for your users to
classify critical content in Power BI without compromising productivity or the ability to
collaborate. Sensitivity labels can be applied on datasets, reports, dashboards, and
dataflows. When data is exported from Power BI to Excel, PowerPoint or PDF files, Power
BI automatically applies a sensitivity label on the exported file and protects it according to
the label’s file encryption settings. This way your sensitive data remains protected no
matter where it is.
