What type of flag is used to mark exception items in the Control Room?

The correct choice is the use of a purple flag to mark exception items in the Control Room. In Blue Prism, flags serve as visual indicators to help users quickly identify the status of various items. The purple flag specifically denotes that an item has encountered an exception, signaling that it requires attention due to an issue arising during process execution.

Using this color-coding system, users can efficiently prioritize and manage their workflow within the Control Room. This feature streamlines incident handling and ensures that exceptions are not overlooked, facilitating smoother process management and enhanced operational efficiency in robotic process automation.
