A technician needs to provide remote support for a legacy Linux-based operating system from their Windows laptop. The solution needs to allow the technician to see what the user is doing and provide the ability to interact with the user's session. Which of the following remote access technologies would support the use case?

A VPN (Virtual Private Network) primarily provides secure access to a network over the internet. While it can encrypt traffic and allow remote access to network resources, it does not offer a graphical interface or the ability to interact with a user’s desktop session. Therefore, it cannot fulfill the requirement of seeing and interacting with the user's screen.

SSH (Secure Shell) is a protocol used for secure command-line access to remote machines. While it allows remote management and secure data transfer, it does not provide a graphical interface for the technician to see or interact with the user's desktop environment, which is required in this scenario.

RDP (Remote Desktop Protocol) is a Microsoft protocol primarily used for accessing Windows desktops remotely. While it offers a graphical interface similar to VNC, it may not be compatible with a legacy Linux system. Therefore, it may not be a viable option for providing remote support in this specific case.
