CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 171:

  A new employee has been issued a company laptop. The employee requests an accessory with a single power source that has wired network connectivity and supports a keyboard, mouse, speakers, and dual monitors. Which of the following accessories should the systems administrator deploy to BEST meet the new user's needs?

  A. PoE switch

  B. USB-C hub with power delivery

  C. Docking station with DisplayPort

  D. KVM switch with audio

  Correct Answer: C

  A docking station is a hardware accessory that allows laptops to connect to multiple peripherals and devices with a single connection. A docking station with DisplayPort would provide the necessary connectivity for the dual monitors, and it can also support the required peripherals such as the keyboard, mouse, and speakers. In addition, it will provide a wired network connectivity for faster and more reliable network access.

• Question 172:

  A technician is troubleshooting a computer that is not completing POST and gets stuck at the manufacturer logo screen. All internal, removable parts have been disconnected and only the minimum parts necessary to POST were

  reconnected.

  However, the symptoms remain the same. Which of the following should the technician try NEXT?

  A. Test the RAM in different slots, one at a time.

  B. Remove and test the power supply.

  C. Replace the motherboard.

  D. Change the CMOS battery.

  Correct Answer: A

  Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won't be able to save any settings in the BIOS, which includes the date and time. If your PC is not booting after removing CMOS, you need to make sure that you have your CPU and RAM connected because it's not possible for your system to boot without those.. Your motherboard and computer will be able to boot just fine even without a CMOS battery present. The only issue is all your BIOS settings will be reset and the time and date will be inaccurate. You will also be unable to save BIOS settings.

• Question 173:

  A company needs to support a 10Gbps throughput. Which of the following is the MINIMUM cable category that could be used?

  A. Cat 5

  B. Cat 5e

  C. Cat 6

  D. Cat 6a

  Correct Answer: C

• Question 174:

  Which of the following wireless technologies has the MOST range and wireless throughput?

  A. 802.11ac

  B. 802.11ax

  C. 802. 11b/gin

  D. 802.11g

  Correct Answer: B

  802.11ax, also known as Wi-Fi 6, has the longest range and the highest wireless throughput of all the wireless technologies listed. References: CompTIA A+ Certification uide, 220-1001, Chapter 3

• Question 175:

  A technician is troubleshooting a laptop that has a blank LCD panel. The technician shines a flashlight into the LCD and sees a faint image. Which of the following BEST describes the issue?

  A. Defective inverter

  B. Incomplete video driver

  C. Incorrect input source

  D. Burned-out bulb

  Correct Answer: A

  an inverter is a device that converts DC power from the laptop's battery or AC adapter to AC power for the backlight of the LCD panel. If the inverter is defective, the backlight will not work and the LCD panel will appear blank or very dim. The user can still see a faint image if they shine a flashlight into the LCD because the LCD itself is still working.

• Question 176:

  A technician is preparing to set up a gaming computer with the following components:

  1.

  Discrete, high-end graphics card

  2.

  Video capture card

  3.

  High-end processor

  4.

  Multiple hard drives

  5.

  USB 3.0 hub

  6.

  Sound card

  Which of the following options is the MOST important for the technician to consider before building the gaming computer?

  A. Redundant power supply

  B. Modular power supply

  C. 20-pin vs. 24-pin power adapter

  D. Power supply wattage rating

  Correct Answer: D

  D. Power supply wattage rating is the MOST important for the technician to consider before building the gaming computer. This is because a high-end graphics card, video capture card, high-end processor, multiple hard drives, and USB 3.0 hub will require a large amount of power to function properly. The wattage rating of the power supply must match the requirements of these components to avoid power problems and instability in the computer. If the power supply is not powerful enough, it can cause component failure, system crashes, and other problems. Thus, it is crucial for the technician to choose a power supply with an adequate wattage rating that can support all the components of the gaming computer.

• Question 177:

  A technician is troubleshooting an old desktop system that randomly shows a Windows BSOD or powers off unexpectedly. All system temperatures are within normal limits. Which of the following should the technician do NEXT?

  A. Visually inspect the motherboard capacitors.

  B. Verify all case fans are operational.

  C. Check that the BIOS version supports the installed CPU.

  D. Compare the software requirements with the installed RAM.

  Correct Answer: A

  BSoDs can be caused by poorly written device drivers or malfunctioning hardware, such as faulty memory, power supply issues, overheating of components, or hardware running beyond its specification limits. In the Windows 9x era, incompatible DLLs or bugs in the operating system kernel could also cause BSoDs.

• Question 178:

  A technician is investigating the output shown on a monitor. The output is clear, but it has a pink hue. The technician has replaced the video card and updated the graphics drivers. Which of the following would be the MOST likely cause?

  A. Physical cabling issues

  B. Burned-out bulb

  C. Display burn-in

  D. Incorrect data source

  Correct Answer: A

  The pink hue is most likely caused by physical cabling issues the output on a monitor is clear but has a pink hue, it could be due to an issue with the physical cabling connecting the monitor to the computer. The video signal may be degraded or distorted due to a damaged or loose cable. The technician should check and replace the cable if necessary to resolve the issue.

• Question 179:

  Which of the following is the MAXIMUM power PoE+ provides?

  A. 15.4W

  B. 30W

  C. 60W

  D. 95W

  Correct Answer: B

  The earliest PoE switches from a few years ago generated 15 Watts per port (IEEE 802.3af). Today, most use the PoE+ standard (IEEE 802.3at), which generates up to 30 Watts per port. That's plenty for most devices that people want to connect
