IPA FE Subject A sample Question 49
A question IPA Japan published in 基本情報技術者試験 科目A サンプル問題 問49, translated into English. ITPEC is based on the same exams.
Which of the following is an appropriate description concerning VDI used for telework?
Explanation
PC environments virtualized on a server and used from outside the company as one's own desktop, from any kind of terminal — VDI stands for Virtual Desktop Infrastructure.
In VDI each user's desktop, with its OS, applications and data, runs as a virtual machine on a server in the data center. The device in the user's hands only sends keyboard and mouse input and receives the screen image, so a PC, a tablet or a thin client can be used, at home or on the move. The data stays on the server rather than on the device, which makes VDI a common basis for secure telework.
Answer (a)
Why not others:
- •(b) — a virtual leased line over the Internet that only specific people can use is a VPN (Internet VPN)
- •(c) — converting paper materials into electronic documents that can be viewed remotely is document digitization with a document management tool
- •(d) — communicating as if face to face over a network is a web or video conferencing tool
Key rule: VDI keeps the desktop on a server and sends only the screen to the user's device; a VPN protects the network path, and conferencing tools carry the conversation.
