CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 51:

  A technician is replacing an older video card with a new high-end video card in a workstation. The installation was successful, the new card seated properly, and power is connected. However, upon booting, the computer now emits several beeps and will not boot, but shows no error messages. Which of the following is MOST likely the cause of this issue?

  A. The BIOS is out-of-date

  B. The is not enough PSU output

  C. There is an onboard RAM mismatch

  D. GPU is overlocked

  E. The firmware is out-of-date

  Correct Answer: B

• Question 52:

  A technician is troubleshooting a Windows CAD workstation that is running slow. The computer uses RAID 10 and has dual GPU cards. The user states that the same application runs faster on an identical workstation.

  Which of the following should the technician perform FIRST to troubleshoot the problem?

  A. Replace the write cache battery.

  B. Check the event log any cache issues.

  C. Clear the RAID configuration file and restart the PC.

  D. Replace the RAID controller write cache module.

  Correct Answer: B

• Question 53:

  A network administrator would like to increase network bandwidth to iGbps between two office buildings that are 0.5mi (805m) apart. Which of the following would be the BEST solution?

  A. Fiber

  B. Coaxial

  C. Plenum

  D. Cat 6

  Correct Answer: A

• Question 54:

  A video game developer is requesting a new desktop computer with eight sticks of memory. The developer wants the desktop computer to take advantage of all available memory bandwidth without sacrificing performance. Which of the following would be the BEST solution?

  A. Triple-channel with DDR5 ECC RAM

  B. Quad-channel with DDR4 RAM

  C. Quad-channel with DDR5 SODIMM

  D. Dual-channel with DDR4 RAM

  Correct Answer: B

  Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops. ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel.

• Question 55:

  The GPS on a user's phone has been unreliable. Which of the following will MOST likely resolve the issue?

  A. Enabling high-accuracy mode

  B. Replacing the battery

  C. Disabling Wi-Fi connections

  D. Utilizing a third-party map application

  Correct Answer: A

  Enabling high-accuracy mode is the most likely action to resolve the issue of unreliable GPS on a user's phone. High-accuracy mode uses multiple sources of location data, such as Wi-Fi, cellular networks, and Bluetooth, to improve the accuracy and reliability of GPS. Replacing the battery, disabling Wi-Fi connections, or utilizing a third- party map application are unlikely to fix the GPS issue, as they are not directly related to the GPS function

• Question 56:

  A user reports that a computer will not turn on. The technician verifies the power cord and the outlet the computer are plugged into are both working properly. Which of the following is the hardware component that has MOST likely failed?

  A. PSU

  B. CPU

  C. RAM

  D. GPU

  Correct Answer: A

  The power supply unit (PSU) is the component that converts AC power from the outlet to DC power for the computer. If the PSU fails, the computer will not turn on. The CPU, RAM, and GPU are not directly related to the power supply and would not prevent the computer from turning on.

• Question 57:

  A technician connects a new computer to the internet and then opens the wiring closet. Even though all of the wires are terminated, nothing in the wring closet is labeled. Which of the following tools should the technician use to complete the task?

  A. Cable tester

  B. Loopback plug

  C. Toner probe

  D. Punchdown tool

  Correct Answer: C

  A toner probe is a tool that can be used to trace and identify cables in a wiring closet. The technician can use a toner probe to find the cable that connects the new computer to the internet. A cable tester is a tool that can be used to check the continuity and quality of a cable. A loopback plug is a tool that can be used to test network ports or cables by sending and receiving signals from the same device. A punchdown tool is a tool that can be used to terminate wires into a patch panel or jack.

• Question 58:

  A user indicates that a laptop is not performing well. A technician determines the laptop has a conventional HDD and that installing a SSD will improve the laptop's performance. Which of the following lists of steps describes what the technician should do to complete the upgrade with the LEAST amount of downtime?

  A. 1. Remove the HDD and install the SSD in the laptop.

  2.

  Install the operating system and necessary applications on the SSD.

  3.

  Connect the HDD to the laptop using a USB enclosure.

  4.

  Copy over all of the user's data.

  B. 1. Leave the HDD in place.

  2.

  Install the SSD in an empty drive bay.

  3.

  Leave all data intact on the HDD.

  4.

  Confirm the SSD is accessible in the operating system.

  C. 1. Connect the SSD to the laptop using a USB enclosure.

  2.

  Clone the HDD to the SSD using cloning software.

  3.

  Remove the HDD.

  4.

  Install the SSD.

  D. 1. Remove the HDD and install the SSD in the laptop.

  2.

  Install the operating system and necessary applications on the SSD.

  3.

  Install the HDD in a USB enclosure.

  4.

  Provide the external HDD for the user to access the old data.

  Correct Answer: C

  The best way to complete the upgrade with the least amount of downtime is to clone the HDD to the SSD using cloning software, and then replace the HDD with the SSD. This way, the user does not have to reinstall the operating system and applications, or copy over their data manually. The other options would either take more time or result in data loss or inaccessibility. Verified References: [How to Upgrade Your Laptop's Hard Drive to an SSD].

• Question 59:

  A user reports that all print jobs sent to a laser printer have random and incorrect characters throughout the pages. Which of the following actions should the technician do to resolve this issue?

  A. Replace the fuser.

  B. Adjust the rollers.

  C. Update the driver.

  D. Shake the toner

  Correct Answer: C

  One of the possible causes of random and incorrect characters appearing on print jobs sent to a laser printer is an outdated or corrupted driver. The driver is a software component that communicates between the operating system and the

  printer, and converts data into a format that the printer can understand. If the driver is outdated or corrupted, it may send incorrect or garbled data to the printer, resulting in poor print quality or errors. The technician should update the driver to

  the latest version from the manufacturer's website, or uninstall and reinstall it if necessary.

• Question 60:

  A company uses legacy accounting software, and no replacement is available. Which of the following virtualization solutions will the company MOST likely select?

  A. Network

  B. Storage

  C. Desktop

  D. Sandbox

  Correct Answer: C

  Desktop virtualization allows multiple virtual desktop instances to run on a single physical computer. This can be a suitable solution for a company using legacy accounting software that may not be compatible with modern operating systems or hardware. By virtualizing the desktop environment, the company can continue to run the legacy software on a virtual machine while maintaining compatibility and isolation from the host system. It provides a way to extend the life of the legacy software without having to find a replacement or upgrade the underlying hardware and operating system.
