A/V editing workstation
Network attached storage device
Network attached storage device
These are the major features of a network attached storage device. The use of onboard video and sound indicate these features are relatively unimportant to the primary task
Your client has a gaming PC that is almost perfect for being used as a graphic/CAD/CAM design workstation. However, one component should be exchanged for a workstation-grade component. Which of these is it?
Graphics card
RAM
Hard disk
Graphics card
Workstation graphics cards are optimized for 2-D/3-D CAD, while consumer graphics cards are optimized for 3-D gaming
Your client wants to use existing computers as thin clients, so you are going through the client’s excess computer inventory looking for suitable candidates. Which of the following would be the most suitable thin client for use with Windows 10 64-bit edition?
Computer with 8 GB of RAM and a 4-TB hard disk
Computer with Intel ATOM and 1 GB of RAM
Computer with Intel Celeron and 2 GB of RAM
Computer with Intel Celeron and 2 GB of RAM
This computer has the smallest amount of RAM supported for use with 64-bit Windows, as well as a processor that meets minimum requirements
You are testing a liquid cooling system in one of your personal systems. Which of the following configurations are you most likely developing?
Virtualization workstation
Gaming PC
Audio/video editing workstation
Gaming PC
Gaming PCs are typically overclocked, and liquid cooling is more effective for cooling than most air coolers
Which of the following device types require(s) account and application setup?
Thick client
Laptops and mobile devices
Thin client
All of the above
