A technician powers on a PC and its monitor and sees the following error message: “No input signal detected” The display lights on the computer are on. Which of the following is a possible solution?

• Checking the power plug on the PC

• Unplug the GPU and plug in to a PCIe Gen 5 slot, if available

• Changing the BIOS settings

• Changing the connector setting on the monitor

• Checking the power plug on the monitor

Changing the connector setting on the monitor

The “No input signal detected” error message typically indicates that the monitor is not receiving a signal form the computer.

Checking the power plug on the monitor and the PC is also important to ensure that both devices are receiving power. However, if the display lights on the computer are on, it’s less likely that a power issue is causing the error message. Changing the BIOS settings is unlikely to resolve this issue, as this error message occurs before the BIOS is loaded.

Documents sent to a printer are printing with abnormally wide margins. You think the paper size is incorrectly selected. Where do you go to make this change?

• Paper selection switch on the printer

• Print queue

• Printing preferences

• Run the troubleshooter

• Manage sharing

Printer preferences

To change the paper sized setting for printer, you should go to the printing preferences, access through the Print dialog box or from the Devices and Printers section in the Control Panel, depending on the operating system being used. Once in the printing preferences, the paper size can be adjusted to match the size of the paper that is currently loaded in the printer.

The print spooler is a service that manages print jobs and allows multiple users to share a printer. It does not provide options to change the paper size. The paper selection switch on the printer is used to physically adjust the paper guides for different paper sized, but it does not change the printer’s settings. The print queue is a list of print jobs waiting to be printed and does not provide options to change the printer’s settings.

A user is no longer able to brows the Internet after returning from vacation. The user is able to log in and navigate to the local intranet, but not to any outside sites. A technician pings a well-known website by name but gets no reply. The technician then pings its IP address and gets a reply. Which of the following commands will MOST likely resolve the issue?

• ipconfig/registerdns

• ipconfig/flushdns

• ipconfig/release

• ipconfig/showclassid

• ipconfig/all

ipconfig/flushdns

Based on the information provided, the issue seems to be related to the DNS resolution. This command will flush the DNS resolver cache, which may contain outdated or incorrect information. By flushing the cache, the system will have to retrieve the latest DNS information from the DNS server, which should resolve the issue.

The fact that the technician was able to ping a website by its IP address but not by its name suggest that the DNS resolution is not working properly.This command clears the DNS cache, resolving name resolution issues.

A technician is tasked with setting up a new workstation for a client. The client requires that the workstation has mirrored storage, using two 4TB drives that can support one failure without data loss. Which of the following BEST meets these requirements?

• RAID -1

• RAID 1

• RAID 5

• RAID 0

• RAID 10

RAID 1

Provides disk mirroring by creating an exact copy of the data on one drive onto the second drive. If one drive fails, the other drive can still operate without data loss.

RAID 0 does not provide any redundancy or fault tolerance and only increases performance by striping (spreading) data across both drives, which would not meet the requirement for mirrored storage.

RAID 5 can provide redundancy with one drive failure, but it requires at least three drives, which is not inline with the requirement of using two 4TB drives.

RAID 10 provides both mirroring and striping, but it requires a minimum of four drives, which again is not in line with the requirement of using two 4TB drives.

A technician is troubleshooting a user’s computer that is not receiving a network connection.

When a computer hibernates, the computer shuts down after saving everything in memory on the your hard disk

True / False

True

When a computer hibernates, the operating system saves the contents of the system’s memory (RAM) to the hard disk, and then shuts down the computer. When the computer is turned back on, it reads the saved information from the hard disk and restores the system to its previous state, allowing the user to resume working from where they left off.

This is different from sleep mode, which is a power-saving state where the computer goes into a low-power mode while still keeping everything in RAM, and wakes up much faster than hibernation.

One feature of virtualization is the ability to quickly add and remove resources to servers depending on your needs at the time. What is the term used to describe this?

• rapid elasticity

• rapid availability

• resource pooling

• metered service

rapid elasticity

Elasticity in virtualization refers to the ability to dynamically adjust the computing resources, such as CPU, memory, storage, and network bandwidth, allocated to virtual machines (VMs) or containers based on the workload demands. This means that resources can be easily scaled up or down, depending on the current demand, without the need for physical changes.

Rapid elasticity is an important feature of virtualization because it allows organization to optimize their resources usage and reduce costs, as they only need to pay for the resources they actually use. Additionally, it enables IT departments to respond quickly to changes in demand and to avoid underutilized resources, which can be wasteful and expensive.

A technician troubleshoot a projector that occasionally power off. The technician recreates the issue and notices the projector will not power back on until approximately 10 minutes have passed. After 10 minutes of being powered on, the projector shuts off again. Which of the following should the technician perform NEXT to resolve the issue?

• Replace the bult

• Clean the filter

• Check the power cable connection

• Adjust the standby timeout

Clean the filter

The symptoms described in the scenario suggest that the projector may be overheating and automatically shutting off as a safety measure to prevent damage to the device. The fact that the projector will not power back on until approximately 15 minutes have passed, and then shuts off again after 15 minutes of being powered on, also supports this theory. Therefore, the next step the technician should perform is to clean the filter.

The filter in a projector is designed to prevent dust and debris from entering the device and blocking the airflow that cools the internal components. Over time, the filter can become clogged with dust and dirt, which can impede the airflow and cause the device to overheat.

Cleaning the filer is a simple and effective way to address this issue. The technician should consult the projector’s manual for instructions on how to access and remove the filter, and then clean it according to the manufacturer’s recommendations. After cleaning the filter, the technician should test the projector to see if the issue has been resolved.

You are a technician who has just replaced a faulty processor in a customer’s computer. Before you can complete the repair, you need to add a cooling mechanism to the new processor to prevent overheating. What should you use to attach the cooling system to the processor?

A substance that improves heat transfer between the processor and the cooling system. It fills microscopic gaps and imperfections between the processor and the cooling system, allowing for better thermal conductivity and more efficient heat dissipation.

It is important to apply the thermal paste properly to ensure good contact and effective heat transfer. A small amount of thermal paste should be placed on the center of the processor, and then spread evenly across the surface using a plastic card or other similar tools. It is important to use the appropriate amount of thermal paste, as too much or too little can affect the cooling performance.

Kate, an accountant reports that after turning on her new laptop, she received a message stating that her IP address is already in use on the system. She tried going back to her old desktop, which she now only uses for email, but received the same message. The technician checks the account and sees a comment that Ann requires a special network setup to connect the banking software. Which of the following should the technician do to resolve the issue?

• Remove the static IP configuration from the desktop

• Replace the network card in the laptop

• Set the laptop configuration to DHCP to prevent conflicts

• Bridge the LAN connection between the laptop and the desktop

Set the laptop configuration to DHCP to prevent conflicts

The error message “IP address already in use on the system” indicates that there is an IP address conflict on the network. This means that another device on the network is using the same IP address as Kate’s laptop and desktop.

Since Kate’s old desktop is only used for email, it is likely that it i still configured with a static IP address, which is causing the conflict. The technician should remove the static IP configuration from the desktop by setting it to obtain an IP address automatically via DHCP.

For the new laptop, the technician should configure the network adapter to use DHCP, which allow it to obtain a unique IP address automatically from the network. This will prevent conflicts with other devices on the network and resolve the issue.

A software component that acts as a buffer between the computer and the printer. The spooler holds the print job in memory until the printer is ready to process it, which helps to ensure that the print job is executed in the correct order and without any interruptions. It also keeps track of the status of each print job and provides feedback to the computer, such as when the print job is completed or if there are any errors. It can also be used to pause, resume, or cancel print jobs, allowing for greater control and management of the printing process.

What is the difference between the print spooler and the print queue?

The print spooler and print queue are closely related but distinct components of the printing process. The print spooler is a software program that manages and temporarily stores print jobs, allowing the computer to continue working while the printer handles the printing tasks. The print queue, on the other hand, is a list or interface that displays the print jobs waiting to be processed.

Print Spooler:

• Acts as a temporary storage area for print jobs. 

• Manages the order in which print jobs are sent to the printer. 

• Ensures efficient use of printer resources by handling multiple print jobs simultaneously. 

• Allows users to continue working while print jobs are being processed

• Print Queue:

  • A visual representation of the print jobs waiting to be processed. 

  • Allows users to see the status of their print jobs, pause, or delete them if needed. 

  • Helps users understand the order in which print jobs will be printed. 

  • Provides a way to manage and monitor the printing process. 

In essence, the spooler is the "engine" that manages the queue, while the queue is the "interface" that allows users to see and interact with the pending print jobs.
