Virtual Desktop Infrastructure (VDI) delivers a desktop operating system hosted on a centralized server and streams the graphical user interface (GUI) to endpoint devices such as thin clients, zero clients, or standard PCs. According to CompTIA Core 1 (220-1201) virtualization objectives, VDI allows users to access their desktop environments remotely while all processing and data remain on the server.
Option A accurately describes this model: a GUI streamed from a server to thin clients. This approach improves centralized management, enhances security, and simplifies endpoint hardware requirements.
Provisioning a sandbox is an example of test or development virtualization, not desktop virtualization. High-performance workstations with a local OS are physical desktops, not VDI. Launching a virtual machine server on a hypervisor describes server virtualization, not desktop delivery.
CompTIA highlights VDI as a common enterprise solution that separates the desktop environment from the physical device, enabling flexibility, scalability, and centralized control.
