You need to create an automated workflow that would send an email to the sales team when numbers on the sales dashboard have been changed. You add a Power BI alert to trigger this flow. 
What are the three data visualizations you can use to set up an alert from the sales dashboard?

Answer options:

A.Pie chart
B.Key influencers
C.KPI
D.Card
E.Bar chart
F.Gauge

Correct Answers: C, D and F 
Power Platform integration between Power BI and Power Automate helps the user to be proactive with their data. You can set up Power BI data alerts when data have been changed on the Power BI dashboard. This alert can serve as a trigger for Power Automate automated flow. 
Power BI limits the data visualizations that can trigger such an alert to three: KPI, Card (single number tile), and Gauge. 
If you want to create a Power BI data alert from a Card (a single number tile) on your dashboard, you can click on a tile and then on the three dots with "More options" (Number1). It will open a menu, and you can select the "Managed alerts" option (Number 2). After that, Power Bi Service opens a new "Managed alert" panel on the right (Number 3). You can use this panel to add a new or edit the already created alert. You need to input an alert name, condition, frequency. And then save and close a panel. On the bottom of this screen, Microsoft provides a direct link to the Power Automate to create a new automated flow based on just created alert (Number 4). 

After the alert is created, you can use an alert name as an Alert ID in your automated flow trigger. 

All other options are incorrect because you cannot set up an alert for these visual tiles.
