Gabby aims to apply a vast range of configurations for the devices used within her organization. Which of the following approaches should she opt for if she has to control hundreds of devices and establish regulations for the usage of SMS and MMS, audio and video recording, GPS tagging, and wireless connectivity features such as tethering and hotspot modes?

A universal endpoint management (UEM) solution is capable of managing various devices including desktops, laptops, mobile devices, and printers. UEM tools rely on mobile applications to configure and manage mobile devices, which makes it the ideal choice for Gabby from the given options. A CASB (Cloud Access Security Broker) is not utilized for managing mobile devices, and the other options require extensive manual effort and are unlikely to succeed, or users might alter the settings whenever it suits them.
