A support technician needs to provide remote assistance to a user who is off-site but connected to the corporate network via VPN. The user's system is running Windows 10 Pro and is governed by strict corporate security policies that do not allow unsupervised control of workstations. Which method should the technician use to ensure adherence to the security policy while still being able to guide the user through troubleshooting steps?
Initiate a video call via Skype and ask the user to share their screen for visual guidance only.
Establish a Remote Desktop Protocol (RDP) session to the user's workstation for unsupervised control.
Configure the workstation for unattended remote access to control the system without the user being present.
Use Microsoft Remote Assistance to view and interact with the user's desktop with the user's explicit permission.
