NEW QUESTION 4

Which of the following is the best example of when to use virtualization?

• A. To manage shared folders by user accounts
• B. To deploy software updates to user machines
• C. To enhance security by centralizing all user desktops
• D. To prevent users from circumventing password policies

Answer: C

Explanation:
One of the benefits of virtualization is that it allows you to create and manage multiple virtual machines (VMs) on a single physical computer. This can be used to enhance security by centralizing all user desktops on a server, rather than storing them on individual user machines. This way, the user desktops can be isolated from each other and from the host machine, preventing malware infections, data breaches, and unauthorized access. Additionally, the user desktops can be easily backed up, restored, updated, and monitored by the administrator, reducing the risk of data loss and downtime.
This type of virtualization is called desktop virtualization, and it separates the desktop environment from the physical hardware the user interacts with1. The user can access their virtual desktop from any device, such as a laptop, tablet, or smartphone, using a remote display protocol. The user experience is similar to using a local desktop, but with improved security and manageability.

NEW QUESTION 5

A user built a new PC with parts sourced torn a popular online vendor. The system boots to the OS and basic browsing works, but whenever the user opens a 4K video or starts to play a game, the system Immediately shuts down. Which of the following is the MOST likely cause of this issue?

• A. The video card was Installed in the wrong PCIe slot.
• B. The CPU heat sink was attached without adequate thermal paste.
• C. The SSD drives do not have enough Pagefile.
• D. The system does not have enough RAM tor 4K video.

Answer: B

Explanation:
Thermal paste is a substance that fills in any gaps between a CPU and its heat sink, which is a device that dissipates heat from the CPU. Without adequate thermal paste, the CPU may overheat and cause the system to shut down automatically to prevent damage. This is especially likely when running 4K video or games, which are more demanding and generate more heat. The technician should check if the CPU heat sink was attached properly and apply enough thermal paste to ensure good contact and heat transfer.

NEW QUESTION 6

A technician is installing a power supply in a workstation that contains a high-end graphics card, a 3GHz processor, and two cooling fans. Which of the following specifications should the technician verify before installing the new power supply?

• A. The wattage
• B. The chassis ventilation
• C. The motherboard's firmware
• D. The cables' color coding

Answer: A

Explanation:
The most important specification that the technician should verify before installing the new power supply is A. The wattage.
The wattage of a power supply is the measure of how much power it can deliver to the components of a computer. The wattage of a power supply should match or exceed the total power consumption of the computer, otherwise the computer may not function properly or may experience instability, overheating, or damage12.
To calculate the total power consumption of a computer, the technician can use a tool such as a power supply calculator, which can estimate the required wattage based on the components and features of the computer. For example, using one of the web search results3, I entered the following information:
•CPU: 3 GHz processor
•GPU: High-end graphics card
•RAM: 16 GB DDR4
•SSD: 1 x 500 GB
•HDD: 1 x 1 TB
•Optical Drive: 1 x DVD-RW
•Fans: 2 x 120 mm
•Other Devices: Keyboard, Mouse, Monitor
The tool estimated that the recommended PSU wattage for this computer is 550 W. Therefore, the technician should verify that the new power supply has at least this wattage before installing it.
The chassis ventilation, the motherboard’s firmware, and the cables’ color coding are not as important as the wattage for installing a new power supply. The chassis ventilation is related to the airflow and cooling of the computer, which can affect the performance and lifespan of the components. The motherboard’s firmware is the software that controls the basic functions of the motherboard, such as booting, input/output, and memory management. The cables’ color coding is a standard way of identifying the function and polarity of the wires in a power supply. However, none of these specifications are directly related to the power delivery or compatibility of the new power supply.

Based on the information provided in the scenario, the most likely cause of the issue is that the user’s internet connection is down (option A). This would explain why the user is unable to access any of the organization’s servers or network items and why web pages are not functioning. However, since the user can still access local file folders and other local machines, it suggests that their local network is still functioning.
The user can access local file folders and other local machines but none of the organization's servers or network items, indicating that the issue is with the user's internet connection, not with the user's domain account, switch, or IP address.
When a user receives a notification indicating that there is limited or no connectivity, it means that their device is unable to establish a connection to the network. In this scenario, the user can access local file folders and other local machines but is unable to access any of the organization’s servers or network items and web pages are not functioning. This suggests that the issue is with the user’s internet connection.
An internet connection allows a device to communicate with other devices and servers outside of its local network. If the internet connection is down or not functioning properly, the device will be unable to access any resources outside of its local network. This would explain why the user in this scenario can still access local resources but is unable to access any of the organization’s servers or network items.
