You need to integrate CA Process Automation with an external application. A data value or status change in the application will result in a CA Process Automation process starting, continuing, or stopping. Which approach enables you to minimize any potential impact on performance?
A. Send an email into a mailbox monitored by a CA Process Automation mail trigger.
B. Continuously poll the external application from the CA Process Automation process to ascertain if data values or statuses in its database change.
C. Continuously check for a predefined file that the external application will be configured to create in a commonly accessible file system when data values or statuses change.
D. Send an event to CA Process Automation from the external application when data values or statuses change with a data payload, which will start, continue, or stop the execution of a designated CA Process Automation process.
