CompTIA 220-1101 Online Questions & Answers

• Question 211:

  A technician just finished building a new PC and needs to install a firmware update for the system board UEFI. The technician is experiencing issues while accessing the USB key. Which of the following features should the technician most likely disable in order to complete this task?

  A. TPM security
  B. USB 3.0 support
  C. PXE boot capability
  D. Secure Boot
  D. Secure Boot

  ---

  Explanation

  Secure Boot is a feature of UEFI (Unified Extensible Firmware Interface) that prevents unauthorized software from running during the boot process. Secure Boot verifies the digital signature of the boot loader and the operating system, and only allows them to run if they are signed by a trusted authority. However, Secure Boot can also prevent some legitimate software, such as firmware updates, from running if they are not signed or recognized by the system. Therefore, the technician may need to disable Secure Boot in order to install a firmware update for the system board UEFI from a USB key34. The other features are not likely to interfere with the firmware update, unless they are misconfigured or incompatible with the USB key. References

• Question 213:

  A technician is adding one more line at the demarcation point. Which of the following tools would be MOST useful to accomplish this task?

  A. Toner
  B. Punchdown
  C. Network tap
  D. Crimper
  B. Punchdown

  ---

  Explanation

  Punchdown tools are used to make connections between wires in a 66/110 block at the demarcation point. The tool is used to insert the wire into the appropriate holes in the block, and it can be used to add additional lines to the demarcation point. The other options are not the correct tools for adding lines to the demarcation point. A toner is used to identify cable pairs, a network tap is used to monitor network traffic, and a crimper is used to terminate cables.

• Question 214:

  An IT manager discovered that hundreds of pages of printed materials are being recycled each day because the materials are left on the printer tray instead of being picked up by users. Which of the following would BEST prevent this waste?

  A. Send friendly reminders to not print unnecessarily.
  B. Enable duplex printing to reduce paper utilization.
  C. Bill each department for the excess material cost.
  D. Require a code or badge before releasing a print job.
  D. Require a code or badge before releasing a print job.

  ---

  Explanation

  By requiring a code or badge before releasing a print job, it ensures that only authorized personnel can collect the printouts. This method is effective in preventing waste and in keeping sensitive documents confidential. Sending reminders, enabling duplex printing, and billing departments are useful strategies for reducing paper utilization but may not necessarily prevent waste caused by uncollected printouts. Requiring a code or badge before releasing a print job is the best solution to prevent the waste of printed materials, as it ensures that only the user who initiated the print job is able to pick up the printed materials. This can be achieved by implementing print release software or requiring users to enter a PIN code at the printer.

• Question 215:

  A frequently used projector continuously shows a message to clean the air filters. The technician checks the filters, and they are dean. Which of the following preconfigured settings is causing the projector to show the message frequently?

  A. Image calibration
  B. Hours of use
  C. Temperature
  D. Image source
  B. Hours of use

  ---

  Explanation

  Projectors typically have built-in timers that track the number of hours the lamp has been in use. When the lamp has been used for a certain number of hours, the projector may prompt the user to clean the air filters as a preventive maintenance measure to ensure proper ventilation and cooling. Even if the filters are clean, the projector's internal timer may still trigger the message based on the accumulated hours of lamp usage.

• Question 216:

  Which of the following is the SAFEST way to replace RAM on a server that has a redundant power supply?

  A. Unplug one power cable.
  B. Verify the RAM temperature.
  C. Utilize a grounding strap.
  D. Replace the RAM while the server is running.
  C. Utilize a grounding strap.

  ---

  Explanation

  Utilizing a grounding strap is the safest way to replace RAM on a server that has a redundant power supply. This ensures that no static electricity is transferred to any of the server components, which could cause permanent damage. The other options are not the correct methods for replacing RAM. Unplugging one power cable is not recommended, as it could cause the server to go offline and disrupt any services that are running. Verifying the RAM temperature is not necessary and does not provide any additional safety measures, and replacing the RAM while the server is running is not recommended, as it could cause system instability.

• Question 217:

  A customer reports that the output from their thermal receipt printer has vertical white lines. Which of the following would most likely resolve this issue?

  A. Replacing the ink cartridge
  B. Using the correct paper type
  C. Installing a maintenance kit
  D. Cleaning the heating element
  D. Cleaning the heating element

  Explanation

• Question 218:

  A technician is troubleshooting a laptop that displays a blank screen when the user turns it on. The technician shines a flashlight into the LCD and sees a faint image. Which of the following is the most likely cause of the issue?

  A. Defective inverter
  B. Incompatible video driver
  C. Incorrect input source
  D. Burned-out bulb
  A. Defective inverter

  ---

  Explanation

  The most likely cause of the issue is a defective inverter. An inverter is a device that converts the direct current (DC) power from the laptop battery or adapter to the alternating current (AC) power that the LCD backlight bulb needs. The backlight bulb is a fluorescent lamp that illuminates the LCD screen and makes the image visible. If the inverter is defective, it may not provide enough power to the backlight bulb, or it may stop working intermittently. This can result in a dim, dark, or blank screen, even though the LCD panel is still functioning and displaying a faint image. To troubleshoot a defective inverter, the technician can follow these steps: Connect an external monitor to the laptop and check if the image is displayed normally. If the external monitor works fine, it means that the laptop video card and driver are not the cause of the issue. Shine a flashlight into the LCD screen and look for a faint image. If the image is visible, it means that the LCD panel is not the cause of the issue. Check the inverter cable and connector for any damage, loose connection, or corrosion. The inverter cable is a thin wire that runs from the laptop motherboard to the inverter board, which is usually located at the bottom of the LCD screen. The inverter connector is a small plug that connects the inverter cable to the inverter board. The technician can try to reseat the inverter cable and connector, or replace them if they are faulty. Check the inverter board for any damage, burn marks, or blown fuses. The inverter board is a small circuit board that contains the inverter and other components. The technician can try to test the inverter board with a multimeter, or replace it if it is defective.

• Question 219:

  A technician is setting up a home network with the following requirements:

  1.Automatic distribution of IP addresses

  2.Internet access

  Which of the following should the technician configure? (Select two).

  A. DHCP
  B. APIPA
  C. VPN
  D. Public IP addresses
  E. Gateway
  F. Static IP addresses
  A. DHCP
  E. Gateway

  ---

  Explanation

  DHCP (Dynamic Host Configuration Protocol) is a protocol that allows a device to automatically obtain an IP address and other network settings from a DHCP server, such as a home router. This simplifies the network configuration and avoids IP address conflicts. DHCP is a common requirement for home networks that have multiple devices that need Internet access. A gateway is a device that connects two different networks, such as a home network and the Internet. A gateway usually performs routing functions, which means it determines the best path for packets to reach their destination. A gateway also often performs NAT (Network Address Translation), which allows multiple devices on a home network to share a single public IP address. A gateway is a necessary requirement for home networks that need Internet access.

  A. The printer needs more RAM
  B. The print server is timing out
  C. The users are not printing in post-script mode
  D. The printer network connection is set to half duplex
  A. The printer needs more RAM
