A help desk technician needs to make administrative changes securely on a remote user's machine. The user must be logged off when the changes are made. Which of the following tools would the…

RDP creates a separate virtual session tied to a user account and by default presents a new login prompt rather than accessing the console at the pre-login screen level, which may conflict with certain administrative scenarios.

VNC mirrors the actual console framebuffer rather than creating a virtual session, meaning it can display and interact with the machine's login screen when no user is authenticated. This allows a technician to perform administrative changes without requiring a logged-in user on the endpoint. Unlike Remote Assistance, VNC does not need the end user to generate or accept an invitation.

Microsoft Remote Assistance requires the local user to generate an invitation file or link and actively grant access, which is incompatible with the requirement that the user be logged off.

SFTP is a secure file transfer protocol used to copy files between hosts and does not provide interactive desktop or GUI-based administrative access.
