CompTIA Updated 220-1101 Exam Questions and Answers by steven

VDI (Virtual Desktop Infrastructure) allows users to access a desktop environment that is running on a server in the data center rather than on the local machine. This is particularly useful for employees who need to work remotely on various devices (A), as it provides a consistent and secure environment regardless of the endpoint device. For a bank with security concerns regarding employee activity (D), VDI offers a centralized management of desktops, enhancing security by keeping sensitive data and applications within the data center and not on the local devices, thus reducing the risk of data breaches.

The issue described in the scenario is most likely caused by the incorrect heat sink being used on the CPU. The heat sink plays a critical role in dissipating heat from the CPU to prevent overheating. If the incorrect heat sink is used, it may not fit properly, leading to insufficient contact with the CPU. This can cause inadequate heat transfer, resulting in the CPU overheating. Overheating can lead to thermal stress on the motherboard, potentially causing shorts near the CPU location as the excessive heat can damage the motherboard's circuits and components.

If a color laser printer's image quality decreases after being serviced for dust removal, it's likely that the servicing process affected the printer's calibration. Calibration ensures that color reproduction is accurate, and if disturbed, can lead to a decrease in image quality. It's important to check and recalibrate the printer to restore its ability to accurately reproduce colors and maintain high image quality.

The appropriate power supply specification for the described workstation setup is 12V, 500W output. This specification ensures that the power supply can handle the combined power requirements of an ATX motherboard, multi-core processor, dedicated graphics solution, SATA hard drive, and DDR4 memory. The 12V rail is crucial for components such as the CPU and graphics card, while a 500W output provides sufficient power overhead to support the system under load, as well as potential future upgrades or additional components.
