CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 531:

  A laser printer, which is located in a large office, has a leaky toner cartridge. Some toner spilled into the printer when the cartridge was removed.

  Which of the following is the best way to clean up the toner?

  A. Magnetic duster

  B. ESD-safe vacuum

  C. Compressed air

  D. Damp cloth

  Correct Answer: B

  Explanation: The best way to clean up the toner that spilled into the printer is to use an ESD-safe vacuum. An ESD-safe vacuum is a special type of vacuum that has a filter that traps toner particles and prevents them from escaping into the air. An ESD-safe vacuum also has a grounding wire that prevents static electricity from building up and damaging the printer's components. Toner is electrically conductive and can cause short circuits or sparks if it contacts sensitive parts of the printer. Therefore, using an ESD-safe vacuum is the safest and most effective method to remove the toner from the printer. Other methods, such as a magnetic duster, compressed air, or a damp cloth, are not recommended for cleaning up toner spills. A magnetic duster is a device that uses a magnet to attract toner particles, but it can also damage the printer's components that rely on magnetism, such as the drum or the fuser. Compressed air can blow the toner around and create a cloud of dust that can be harmful to breathe or contaminate other parts of the printer. A damp cloth can smear the toner and make it harder to remove, as well as cause corrosion or rust on the printer's metal parts.

• Question 532:

  Which of the following internet connection types would be the most readily available for users located on unimproved land that lacks infrastructure?

  A. Fiber

  B. Cable

  C. DSL

  D. Satellite

  Correct Answer: D

  Explanation: Satellite internet is the most widely available internet connection type, as it does not depend on cables or wires. It can reach remote areas that lack infrastructure for other types of internet connections1. References: Satellite Internet

• Question 533:

  A customer recently installed a new graphics card, but the card's HDMI port is not getting a signal when connected to the monitor. When the monitor is connected to the original HDMI port, located next to the USB ports, everything works as expected. Which of the following should the technician do next?

  A. Change the input source selection on the monitor.

  B. Check to see whether the UEFI setting for PCle graphics is enabled.

  C. Install a higher wattage power supply.

  D. Test the new graphics card with an HDMI to DVI adapter.

  Correct Answer: B

• Question 534:

  A customer's laptop is making clicking sounds in the area where non-volatile storage is installed. A technician examines the laptop and confirms the issue. Which of the following is the most appropriate replacement part?

  A. 7,200rpm HDD

  B. NVMe SSD

  C. M.2 SATA SSD

  D. SCSI 15,000rpm HDD

  Correct Answer: B

  Explanation: NVMe stands for Non-Volatile Memory Express, and it is a type of SSD (solid state drive) that uses PCIe (Peripheral Component Interconnect Express) interface to connect to a computer. NVMe SSDs offer faster performance and lower latency than other types of SSDs, such as SATA (Serial ATA) or M.2 SATA. If a user reports that a PC occasionally fails to boot and makes clicking sounds in the area where non-volatile storage is installed, it indicates that the hard drive is failing and needs to be replaced with an NVMe SSD.

• Question 535:

  A technician is replacing the toner cartridge in a laser printer. Which of the following steps should the technician complete first? (Select two).

  A. Check the expiration date of the cartridge.

  B. Ensure the cartridge is the correct model.

  C. Open the toner compartment.

  D. Remove the sealing tape.

  E. Run the cleaning utility.

  F. Calibrate the printer.

  Correct Answer: BC

  Explanation: The technician is unable to access the company portal website, but other websites work fine. This suggests an issue with resolving the specific URL of the company portal, which is a function of DNS.

  Here's why other options are not the most likely cause:

  DHCP reservations: This is not relevant as the issue persists even when the technician tries a different workstation, indicating a problem beyond individual device configuration. Static IP addresses: Similar to DHCP reservations, static IPs are

  not likely the cause as both affected workstations are experiencing the issue. Default gateway: While the default gateway is necessary for internet access, other websites are working, making it less likely to be the root cause.

• Question 536:

  A user is experiencing an issue when trying to use a wireless headset with a mobile phone. The device was previously paired with the phone but is unable to connect when switched on. Which of the following should the user enable on the phone to remediate the issue?

  A. Bluetooth

  B. Near-field communication

  C. Tether

  D. Wi-Fi

  Correct Answer: A

• Question 537:

  A user has been having issues charging a laptop after turning it on and has noticed the laptop screen is dim. Which of the following components most likely needs to be replaced?

  A. LCD

  B. Video card

  C. Digitizer

  D. inverter

  Correct Answer: D

  Explanation: An inverter is a component that converts DC power to AC power for the backlight of an LCD (liquid crystal display) screen. If the inverter is faulty, the screen may appear dim or dark, even if the brightness settings are adjusted.

  Replacing the inverter may fix the issue. The LCD itself, the video card, and the digitizer are not related to the screen brightness problem.

• Question 538:

  An administrator needs to configure RAID for a video-rendering workstation at minimal cost. The solution should have high read/write performance and maximum drive storage utilization. Redundancy is not a concern. Which of the following RAID configurations should the administrator use?

  A. 0

  B. 1

  C. 5

  D. 10

  Correct Answer: A

  Explanation: The administrator should use RAID 0 for a video-rendering workstation at minimal cost. RAID 0, also known as striping, is a RAID configuration that splits data evenly across two or more disks, without parity information,

  redundancy, or fault tolerance. RAID 0 has the following advantages and disadvantages:

  High read/write performance: RAID 0 can increase the data transfer rate by using multiple disks in parallel. This can improve the speed and efficiency of video rendering, which involves processing large amounts of data. RAID 0 can also

  reduce the latency and seek time of the disks, as the data is distributed across multiple spindles.

  Maximum drive storage utilization: RAID 0 can use the full capacity of the disks, without wasting any space for parity or mirroring. This can lower the cost and increase the storage space for the workstation. For example, if two 500 GB disks

  are used in RAID 0, the total capacity of the array will be 1000 GB. No redundancy or fault tolerance: RAID 0 does not provide any protection against data loss or disk failure. If one disk fails, the entire array will fail and the data will be

  unrecoverable. Therefore, RAID 0 should only be used for non-critical data that is backed up elsewhere, or for temporary files that can be recreated.

• Question 539:

  A customer reports that a printer is only printing misaligned images. Which of the following should the technician do to correct the issue?

  A. Clean the print heads.

  B. Perform a calibration.

  C. Replace the ink cartridge.

  D. Scan the document.

  Correct Answer: B

  Explanation: Calibration is the process of adjusting the printer settings to ensure that the printed output matches the original document. Calibration can fix issues such as misaligned images, color accuracy, and print quality. References: [Printer Calibration]

• Question 540:

  A technician is installing a WAP in the company break room. The new access point should have a rating of higher than 50Mbps and minimal range to avoid interference with other access points. Which of the following 802.11 standards should the technician select?

  A. Ac

  B. B

  C. G

  D. n

  Correct Answer: A

  Explanation: Ac stands for 802.11ac, which is a wireless networking standard that operates in the 5 GHz frequency band and offers a maximum data rate of 1.3 Gbps. 802.11ac is also backward compatible with 802.11a, 802.11b, 802.11g, and 802.11n standards. If a technician wants to install a WAP (wireless access point) in the company break room that has a rating of higher than 50 Mbps and minimal range to avoid interference with other access points, they should select the 802.11ac standard.
