You create an automated Power Automate flow. 
What tool does help compose your flow without errors?

Answer options:

A.Power Automate Analytics
B.Run history
C.Power Apps Analytics
D.Flow checker
E.Cloud Flow Activity

Correct Answer: D 
Flow checker is a Power Automate service that monitors the creation of the flow. It helps you to spot errors and follow the best flow design practices. If you made an error or missed a required input, the Flow checker will alert you with a red dot on its icon. 

When you click on the marked icon, the Flow checker panel shows you the errors and the step names. You can get back to your flow and correct the errors. 

Options A is incorrect because Power Automate Analytics provides information about all running flows in the environment, but it does not verify your flow on errors before it is deployed.
Options B is incorrect because Run history provides information about the running flow`s success, but it does not verify your flow on errors before it is deployed.
Options C is incorrect because Power Apps Analytics provides information about all running apps in the environment, but it does not verify your flow on errors before it is deployed.
Options E is incorrect because Cloud Flow Activity provides information about the runs of the flows in the environment, but it does not verify your flow on errors before it is deployed.
