Question 1

DRAG DROP
An application needs to calculate if the product meets a determined quality specification, activate an automation to remove
poor quality products, and report detailed results back to the cloud. All data are captured from an application that is
connected to a sensor. Using the SDK of the cloud provider, drag and drop the tasks that must be completed from the left to
the right. Not all options are used.
