NEW QUESTION 4

A technician has noticed that a monitored server is receiving a disk failure notice during startup. When the technician clicks to continue, the machine still seems to startup into Windows but at a much slower speed. The technician looks at the BIOS information and sees the machine utilizes a RAID 5 configuration. Which of the following does the technician MOST likely need to perform?

• A. Reinstall the HDD drivers.
• B. Rebuild The RAID.
• C. Replace the failed drivers.
• D. Restart the system.

Answer: B

Explanation:
The disk failure notice during startup indicates that one or more disks in the RAID array have failed. The machine still seems to startup into Windows but at a much slower speed because the RAID 5 configuration can tolerate one disk failure and still operate, but with reduced performance and reliability. The technician most likely needs to rebuild the RAID, which means replacing the failed disk(s) and restoring the data from the parity information. Reinstalling the HDD drivers will not fix the disk failure. Replacing the failed drivers is not a valid option, as drivers are software, not hardware. Restarting the system will not fix the disk failure either. References: https://www.comptia.org/blog/what-is- raid-0-1-5-6-10

NEW QUESTION 10

A technician tries installing different toners to fix a printer that is printing blank pages, but the issue persists. Which of the following is most likely causing the issue?

• A. Printer drum
• B. Printer ink
• C. Environmental temperature
• D. Corrupted printer drivers

Answer: A

Explanation:
A printer drum is a component of a laser printer that transfers the toner to the paper. It is a cylindrical metal or plastic piece that is coated with a photosensitive material. The drum is charged by a laser beam, which creates an electrostatic image of the document to be printed. The toner then sticks to the charged areas of the drum, and the drum rolls over the paper, transferring the toner to the paper and creating the printout1.
If the printer drum is damaged, worn out, or dirty, it may not be able to transfer the toner properly, resulting in blank pages. According to some web search results23, some signs that a printer drum needs to be replaced are:
•Faint, light, faded, or blank printed pages
•Streaks, spots, or lines on the printed pages
•Error messages indicating a drum problem
To fix this issue, the technician may need to clean or replace the printer drum. Some web search results12 provide instructions on how to perform a manual drum cleaning or replacement.
Printer ink is not a likely cause of the issue, since the user has already tried installing different toners and the issue persists. Toner is the powder used by laser printers, while ink is the liquid used by inkjet printers. They are not interchangeable4.
Environmental temperature is not a likely cause of the issue, since most printers can operate in a wide range of temperatures. However, extreme temperatures may affect the quality and performance of some printers. For example, high temperatures may cause ink to dry out or toner to clump, while low temperatures may cause ink to freeze or toner to become brittle.
Corrupted printer drivers are not a likely cause of the issue, since they would affect the communication between the printer and the computer, not the printing process itself. Corrupted printer drivers may cause errors, delays, or incorrect outputs, but not blank pages.

NEW QUESTION 11

A user reports that a printer pulls multiple sheets of paper from the paper tray instead of a single sheet. Which of the following should a technician
investigate to resolve this issue? (Select two).

• A. Toner cartridge
• B. Tractor feed
• C. Pickup roller
• D. Separation pad
• E. Duplexer
• F. Fuser

Answer: CD

Explanation:
The correct answers are C. Pickup roller and D. Separation pad.
A pickup roller is a rubber wheel that grabs the paper from the paper tray and feeds it into the printer. A separation pad is a small piece of cork or rubber that prevents more than one sheet of paper from being fed at a time. If the pickup roller or the separation pad is worn out, dirty, or damaged, it can cause the printer to pull multiple sheets of paper instead of a single sheet. This can lead to paper jams, misprints, or wasted paper.
To resolve this issue, a technician should investigate the condition of the pickup roller and the separation pad and replace them if necessary. The technician should also clean the paper tray and make sure the paper is loaded correctly and not stuck together.
A toner cartridge is a component that contains the toner powder used to create the printout on a laser printer. A tractor feed is a mechanism that uses sprockets to move continuous paper through a dot matrix printer. A duplexer is a device that allows a printer to print on both sides of the paper automatically. A fuser is a part of a laser printer that melts the toner onto the paper using heat and pressure. None of these components are related to the issue of pulling multiple sheets of paper from the paper tray.

NEW QUESTION 12

A customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point. Which of the following
should the technician verify first?

• A. The internal antennas are connected.
• B. The device has the latest OS updates.
• C. The wireless device drivers are the latest version
• D. Airplane mode is disabled.
• E. The battery is charging.

Answer: A

Explanation:
The internal antennas are the components that allow the laptop to receive and transmit wireless signals from and to the wireless access point. The internal antennas are usually located inside or around the laptop screen, and they are connected to the wireless network card or adapter by thin wires or cables. If the internal antennas are disconnected, damaged, or misaligned, the laptop may experience wireless connectivity issues, such as low signal strength, limited range, or intermittent connection.
In this scenario, a customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network if it is positioned very close to a wireless access point. This could indicate that the technician accidentally disconnected or damaged the internal antennas during the screen replacement process, and that the laptop is not receiving enough wireless signals from the wireless access point. Therefore, the first thing that the technician should verify is that the internal antennas are properly connected and positioned inside or around the laptop screen.
To verify and reconnect the internal antennas, the technician should follow these steps :
✑ Turn off the laptop and disconnect it from any power source or external device.
✑ Remove the battery and any screws that secure the laptop screen bezel.
✑ Carefully pry off the laptop screen bezel and expose the internal antennas.
✑ Check if the internal antennas are intact and securely connected to the wireless network card or adapter. The internal antennas may have different colors or labels, such as black, white, gray, main, aux, or 1, 2.
✑ If the internal antennas are disconnected or loose, reconnect them to the corresponding connectors on the wireless network card or adapter. Make sure that they snap into place and that there is no gap or bend in the wires or cables.
✑ If the internal antennas are damaged or broken, replace them with compatible ones. Make sure that they have the same length and shape as the original ones.
✑ Realign and reposition the internal antennas inside or around the laptop screen.
Make sure that they do not interfere with any other component or cable, and that they follow the original path and direction.
✑ Reattach the laptop screen bezel and secure it with screws.
✑ Reinsert the battery and turn on the laptop.
✑ Test the wireless connectivity and performance of the laptop.
