Question
A technician is configuring a virtual desktop for remote employees. Which protocol should be used for secure remote access to the virtual desktop?
A. VNC

D. Telnet
E. FTP
Answer
C. RDP
Explanation
Remote Desktop Protocol (RDP) is commonly used for secure access to virtual desktops, providing encrypted communication and robust remote control features.
Remote Desktop Protocol (RDP) is a Microsoft-developed protocol specifically designed for secure, remote access to desktops and virtual machines. RDP provides encrypted communication, robust authentication, and advanced features such as audio/video redirection, printer and file system redirection, and bandwidth optimization, making it ideal for virtual desktop infrastructure (VDI) environments.
RDP sessions are protected using 128-bit encryption and Transport Layer Security (TLS), ensuring that data transmitted between the client and virtual desktop remains confidential and secure. RDP is widely supported across Windows, Linux, and macOS platforms, and is the industry standard for remote desktop access in enterprise and cloud environments.
Other options:
- VNC: Offers remote desktop access but is generally less secure by default and lacks some of RDP’s advanced security and integration features.
- SSH: Used for secure command-line access, not for full graphical desktop sessions.
- Telnet and FTP: Not secure and not intended for remote desktop access.
RDP is purpose-built for secure, feature-rich remote desktop access and is the recommended protocol for virtual desktop deployments.
