Question 474 - 220-1102 discussion

VNC (Virtual Network Computing) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a graphical user interface. VNC does not require an external internet connection, as it works over a local network or a VPN. VNC uses a client-server model, where the server runs on the remote desktop and the client connects to it from another device.VNC can transmit the keyboard and mouse events from the client to the server, and the screen updates from the server to the client, enabling the technician to interact with the remote desktop as if it were local12.

VNC is a better option than the other choices because:

RMM (Remote Monitoring and Management) (B) is not a single software solution, but a category of software solutions that enable IT professionals to remotely monitor, manage, and troubleshoot multiple devices and networks. RMM software may include remote access tools, but also other features such as patch management, backup and recovery, security, reporting, and automation.RMM software may require an external internet connection, as it often relies on cloud-based services or web-based consoles34.

RDP (Remote Desktop Protocol) is a remote access tool that allows the technician to access and control Windows desktops on the company LAN using a graphical user interface. However, RDP is not compatible with Linux or macOS desktops, unless they have third-party software installed that can emulate or translate the RDP protocol.RDP also has some security and performance issues, such as encryption vulnerabilities, bandwidth consumption, and latency problems56.

SSH (Secure Shell) (D) is a remote access tool that allows the technician to access and control various Windows, Linux, and macOS desktops on the company LAN using a command-line interface. SSH does not require an external internet connection, as it works over a local network or a VPN. SSH uses encryption and authentication to secure the communication between the client and the server.However, SSH does not provide a graphical user interface, which may limit the functionality and usability of the remote desktop7.
