Before deploying an application update broadly, best practice is to test it in an isolated environment to avoid breaking production systems. The All-in-One guide defines sandbox testing clearly: “a sandbox is a place where you can experiment without messing up the primary system,” typically a virtualized environment, and it “entails checking out new and updated applications without putting the systems and data you depend on at risk.” That directly aligns with rolling out a new application update across the organization.

Mike Meyers’ Lab Manual repeats the same concept: sandbox testing uses an isolated environment and snapshots to test changes safely before production deployment. It’s positioned as a documented business process within change-management best practices, reinforcing why it comes early—before impact spreads.

A backup/rollback plan is important too, but the question asks for the first step when applying a new update to everyone. Testing first helps identify compatibility issues, installation failures, and side effects early—so you don’t deploy a bad update at scale. Therefore, Sandbox testing (C) is correct.

In Windows, accessibility tools such as speech recognition are found under the Ease of Access settings. This section includes options for users who require assistive technologies, including screen readers, magnifiers, and voice control interfaces like speech recognition. Setting up speech recognition allows users to control the system and input text using voice commands.

A. Time and Language is for setting regional preferences and language packs.

B. Personalization adjusts themes, backgrounds, and colors.

C. System includes display, storage, notifications, and power settings, but not accessibility tools.

Because the employee needs graphical interface (GUI) access to Linux servers, the best option is VNC (Virtual Network Computing). VNC is specifically designed for remote control and sharing of desktops, meaning it can present the full graphical desktop of the Linux server to the remote user and allow interaction as if they were sitting at the machine. Quentin Docter describes VNC as “a remote control tool for the sharing of desktops,” typically using TCP port 5900, and notes it is similar to RDP but is an open-source protocol; it can support encryption via plug-ins (important for secure remote use). Mike Meyers’ Lab Manual reinforces the key distinction: SSH provides command-line access, but “when you need remote access to the full graphical desktop, you need a remote desktop application,” and many of those use VNC (or RDP).

By contrast, SSH and Telnet are primarily text-console tools (Telnet is also unencrypted/insecure), and WinRM is Windows-focused remote management rather than the standard way to provide GUI access to Linux desktops.
