Explanation
VNC (Virtual Network Computing) attaches to the physical console session of a remote machine, allowing a technician to interact with the login screen when no user is logged in, which satisfies the requirement to work while the user is logged off.
Common mistakes.
- A. 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.
- C. 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.
- D. SFTP is a secure file transfer protocol used to copy files between hosts and does not provide interactive desktop or GUI-based administrative access.
Concept tested. VNC remote console access with user logged off
