Desktop Virtualization & VDI for A+
Short answer
Local desktop virtualization means the VM runs on the user's own hardware and the user connects directly to that guest OS. VDI means the desktop session is hosted on central servers and delivered to the user; the device may act as a thin client. From a support perspective, VDI scenarios imply network and central-server considerations, while local VM scenarios imply local resource and host-level support tasks.
Why it appears on the exam
- Given a scenario highlighting centrally hosted desktops, pick VDI and justify based on central hosting or thin-client cues. - Given a scenario describing a user running a VM on their laptop, pick local desktop virtualization and note host resource considerations.
Key concepts
Concept 1
Required terms
Virtual Desktop Infrastructure (VDI): A centrally hosted virtual desktop environment that users access from client devices; the desktop runs on remote infrastructure rather than locally on the user's machine. desktop virtualization: Any virtualization approach that provides a desktop environment in a virtual environment, either local (on the device) or remote (VDI). Virtual Desktop Infrastructure (VDI): a centrally hosted virtual desktop environment accessed from client devices. desktop virtualization: providing a desktop environment in a VM, either locally or remotely.
Example
A company uses central servers to provide employee desktops accessible from multiple devices: VDI.
Concept 2
How Desktop Virtualization & VDI works
Local desktop virtualization means the VM runs on the user's own hardware and the user connects directly to that guest OS. VDI means the desktop session is hosted on central servers and delivered to the user; the device may act as a thin client. From a support perspective, VDI scenarios imply network and central-server considerations, while local VM scenarios imply local resource and host-level support tasks.
Example
A user runs Windows 10 in a VM on their laptop for testing: local desktop virtualization.
Concept 3
Common confusion
- Equating VDI with any virtual desktop: VDI specifically implies central hosting and remote delivery. - Assuming VDI problems are solved like local VM issues: VDI support often involves network and central infrastructure, which is beyond A+ scope for architecture.
Example
A company uses central servers to provide employee desktops accessible from multiple devices: VDI.
Concept 4
Core 1 (220-1201) question cues
Given a scenario highlighting centrally hosted desktops, pick VDI and justify based on central hosting or thin-client cues; Given a scenario describing a user running a VM on their laptop, pick local desktop virtualization and note host resource considerations.
Example
A user runs Windows 10 in a VM on their laptop for testing: local desktop virtualization.
