Which device enrollment settings are valid?

In the context of device enrollment settings within CyberArk's solution:

A.Send notification on device enrollment:This is a valid setting that enables administrators to be notified when a device is enrolled. It is important for maintaining visibility over the devices being added to the system.

B.Enable invite-based enrollment:This setting is valid and allows for a controlled enrollment process where users can only enroll their devices after receiving an invite. This helps in managing and securing the enrollment process by ensuring that only authorized devices are added.
