CompTIA 220-1101 Online Questions & Answers

• Question 811:

  An analyst has replaced the motherboard in a desktop computer that previously overheated. The analyst presses the power button, hears three beeps, and sees the screen is black.

  Which of the following is the best action for the analyst to take to fix this issue?

  A. Replace the power supply.
  B. Reseat the RAM.
  C. Reattach the hard drive.
  D. Flash the BIOS.
  B. Reseat the RAM.

  ---

  Explanation

  three beeps and a black screen indicate a memory error of some sort123. This means that the RAM may not be properly installed or connected to the motherboard. Reseating the RAM means removing each stick and re-inserting it, making sure it clicks into place. This can sometimes solve the problem by ensuring a good contact between the RAM and the motherboard. Replacing the power supply, reattaching the hard drive, or flashing the BIOS are unlikely to fix this issue, since they are not related to the memory error. The power supply provides power to the whole system, the hard drive stores data, and the BIOS is the firmware that controls the boot process. None of these components would cause three beeps and a black screen if they were faulty.

• Question 813:

  A technician is troubleshooting a burning smell on a desktop computer. The technician determines that the odor is coming from inside the device.

  Which of the following should the technician do first?

  A. Unplug the computer.
  B. Locate a fire extinguisher.
  C. Call the fire department.
  D. Remove the desktop cover.

• Question 814:

  A service technician replaced the gateway, and a user is now unable to access the SOHO wireless network. Which of the following steps should the technician take to resolve the issue?

  A. Assess the network cables for damage.
  B. Disable Bluetooth connections.
  C. Update the firmware.
  D. Check if the password and SSID are correct
  D. Check if the password and SSID are correct

  ---

  Explanation

  Checking if the password and SSID are correct is the best step that the technician should take to resolve the issue of a user being unable to access the SOHO wireless network after replacing the gateway. The new gateway may have a different password and SSID than the old one, which would prevent the user from connecting to the wireless network. The technician should verify that the user has entered the correct password and SSID for the new gateway. Assessing the network cables for damage, disabling Bluetooth connections, or updating the firmware are not likely to solve the issue, as they are not related to the wireless network authentication

• Question 815:

  A company needs to keep a record of tasks performed by an application.

  Which of the following should the company most likely implement as part of a solution?

  A. Fileshare
  B. Syslog
  C. Database
  D. SAN
  B. Syslog

  ---

  Explanation

  Syslog is used to log system events and tasks performed by applications, providing a centralized record of activity.

  Why Not A (Fileshare): Fileshares store files but are not designed for event logging.

  Why Not C (Database): Databases can store logs but are not a logging mechanism themselves.

  Why Not D (SAN): A SAN is a storage solution, not a logging tool.

• Question 816:

  A technician receives several error alerts on a server after an unexpected reboot. A message states that one or more disks are in a degraded state. When the technician advances to the next error message, it indicates the OS is missing. Which of the following are the MOST likely causes of these errors? (Choose two.)

  A. Missing drives in the OS
  B. RAID failure
  C. Bootable device not found
  D. Data loss
  E. Controller failure
  F. CMOS corruption
  G. TPM malfunction
  B. RAID failure
  C. Bootable device not found

  ---

  Explanation

  The message stating that one or more disks are in a degraded state is a clear indication of a RAID failure. RAID stands for Redundant Array of Independent Disks, and it is a technology used to provide fault tolerance and improve performance by combining multiple hard drives into a single logical unit. The message indicating that the OS is missing is most likely caused by a bootable device not found. This means that the server is unable to boot from the designated boot device, which could be the hard drive, a CD/DVD drive, or a USB flash drive. This could be caused by a faulty boot device, a loose cable, or a misconfiguration in the BIOS or UEFI settings.

• Question 817:

  Which of the following is the MOST likely cause for a network PC to have an APIPA address?

  A. DHCP failure
  B. DNS resolution
  C. Duplicate IP address
  D. Cleared ARP cache
  A. DHCP failure

  Explanation

• Question 818:

  A network technician needs to connect into the console of a switch. Which of the following connection types should the technician most likely utilize?

  A. Serial interface
  B. Bluetooth
  C. Near-field communication
  D. Port replicator
  A. Serial interface

  ---

  Explanation

  A serial interface is a common way to connect to the console port of a switch using a rollover cable and a terminal emulator program. This allows the network technician to configure and troubleshoot the switch. Bluetooth, near-field

  communication, and port replicator are not used for console connections.

• Question 819:

  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
  A. PSU

  ---

  Explanation

  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 820:

  A user frequently edits large files and saves them locally on a laptop_ The user has recently begun experiencing performance issues and needs a cost-effective hardware upgrade.

  Which of the following is the best way to meet the user's requirements?

  A. Upgrade the memory
  B. Upgrade to a larger GPU.
  C. Upgrade to an SSD.
  D. Upgrade to a faster CPU.
  C. Upgrade to an SSD.

  ---

  Explanation

  Upgrading to an SSD (Solid State Drive) is the best way to meet the user's requirements because it will improve the performance and storage capacity of the laptop. SSDs are faster than HDDs (Hard Disk Drives) because they have no moving parts and can access data more quickly. SSDs also have lower power consumption, lower heat generation, and higher reliability than HDDs. Therefore, upgrading to an SSD will make the laptop more responsive, boot faster, and handle large files better. According to some web sources, SSDs are the best hard drives for video editing because they can streamline the workflow and store masses of footage in one easy-to-access place1. SSDs are also one of the most common PC upgrades that can make a dramatic difference, especially for aging systems2. Additionally, Adobe recommends using SSDs for Premiere Pro and After Effects because they can handle large media files and cache data more efficiently3.
