The correct answer is Bring your own device (BYOD). This model allows employees to use their personal devices to access corporate resources while maintaining the security of the company's data. The IT department will use MDM solutions to create a secure container for corporate data on personal devices. It enables the management of corporate applications and data without taking full control of the personal device, providing a balance between security and privacy. Corporate-owned, personally enabled (COPE) provides devices owned by the company to the employees, which doesn't apply here because employees are using their own devices. Choose your own device (CYOD) involves employees choosing from a list of approved devices provided by the company, which is also not applicable in this scenario. Lastly, Corporate-owned, business-only (COBO) is when the company owns the device and restricts it to business use only, which is not suitable for personal devices.
