Question 29

VNC is the appropriate remote access technology for this scenario.

VNC (Virtual Network Computing) allows a technician to see the user's session and interact with it on a legacy Linux-based operating system from a Windows laptop. This capability makes it ideal for providing effective remote support.

A) VPN

A VPN (Virtual Private Network) provides secure access to a network but does not allow the technician to view or interact with the user's session. It primarily encrypts internet traffic and maintains privacy rather than facilitating direct interaction with the desktop environment.

B) VNC

VNC enables the technician to view and control the user’s desktop, making it suitable for remote support on a legacy Linux system. This technology allows for real-time interaction with the user's activities, which is essential for effective troubleshooting and assistance.

C) SSH

SSH (Secure Shell) is primarily used for secure command-line access and does not provide a graphical interface. While it can be used to manage Linux systems, it does not meet the requirement for viewing and interacting with a user's graphical session.

D) RDP

RDP (Remote Desktop Protocol) is designed for Windows environments and does not support remote access to Linux-based systems without additional configuration. Therefore, it is not a suitable choice for providing support on a legacy Linux operating system.

Conclusion

VNC is the most appropriate technology for the given scenario as it allows for both viewing and interaction with the user's session on a Linux system. Other options, such as VPN, SSH, and RDP, either do not support graphical sessions or are not compatible with Linux, making them unsuitable for this specific use case.
