CompTIA 220-1101 Online Questions & Answers

• Question 621:

  A laptop PC user is reporting issues with the hard drive. A filesystem check shows that all files are accessible and the filesystem is clean. After the check, the PC still issues a hard drive error message. Which of the following is the MOST likely cause of the error?

  A. S.M.A.R.T failure
  B. IOPS failure
  C. DIMM failure
  D. RAID failure
  A. S.M.A.R.T failure

  ---

  Explanation

  If the filesystem check shows that all files are accessible and the filesystem is clean, but a hard drive error message persists, it's possible that the hard drive is experiencing S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) failure. This is a warning system built into hard drives to alert users of potential issues before they become critical.

• Question 622:

  A technician needs to install RAM into a rackmount server that will be used as a VM host. Which of the following would be BEST to install?

  A. SODIMM
  B. VRAM
  C. DDR4
  D. ECC
  D. ECC

  ---

  Explanation

  When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash.

  When installing RAM into a rackmount server that will be used as a VM host, it would be best to install ECC (Error Correcting Code) RAM which can detect and correct common types of data corruption.

• Question 623:

  A user is unable to access the internet, but other users in the same office are not having an issue. All users' devices are hardwired to the network.

  Which of the following tools should the technician use to determine the issue?

  A. Loopback plug
  B. Network tap
  C. Wi-Fi analyzer
  D. Punchdown tool
  A. Loopback plug

  ---

  Explanation

  A loopback plug is a diagnostic tool used to test the functionality of network interfaces by creating a signal loop. In this case, since the user's device is hardwired to the network but cannot access the internet, using a loopback plug can help determine whether the issue is with the network interface card (NIC) or the Ethernet cable.

  Loopback plug: This tool helps test whether the computer's network interface is functioning properly.

  Why the other options are incorrect:

  Network tap: A network tap is used to monitor network traffic, but it wouldn't help diagnose the local connectivity issue here.

  Wi-Fi analyzer: This tool is used to troubleshoot Wi-Fi networks, but since the issue is with a hardwired connection, it's not applicable. Punchdown tool: A punchdown tool is used to connect network cables to a patch panel or keystone jack. It is not used for diagnosing network issues.

  This falls under the Hardware and Network Troubleshooting domain in the CompTIA A+ Core 1 exam.

• Question 624:

  An end user's domain password expires while they are working from home. The end user tries to reset the password using Ctrl+Alt+Delete and then receives the following message:

  Configuration information could not be read from the domain controller, either because the machine is unavailable or because access is denied.

  Which of the following will resolve this issue?

  A. Restart the computer.
  B. Connect to the VPN.
  C. Reset the account in Active Directory.
  D. Join the Wi-Fi network.
  B. Connect to the VPN.

• Question 625:

  A customer reports that access to the network fileshare has become much slower than usual, but local applications do not seem to have trouble. The technician checks the download bandwidth and finds no issues. Which of the following should the technician check NEXT?

  A. Level of network utilization
  B. Customer use of two-factor authentication
  C. Amount of local drive space
  D. RAID array drive health
  A. Level of network utilization

  ---

  Explanation

  The technician should check the level of network utilization to determine if there is an excessive amount of traffic that may be causing the slow access to the network fileshare. This can be done using network monitoring tools to track the amount of data being transmitted on the network.

• Question 626:

  A company uses vital legacy software that does not run in the current OS version.

  Which of the following will best support the software while keeping the OS current?

  A. Shared resources
  B. System sandbox
  C. Test development
  D. Application visualization
  D. Application visualization

  ---

  Explanation

  Application virtualization allows legacy software to run in a virtualized environment while the operating system remains current. It isolates the application from the OS, ensuring compatibility without downgrading the OS.

  Why Not A (Shared resources): This relates to resource sharing, not application compatibility.

  Why Not B (System sandbox): Sandboxes isolate applications for security testing, not compatibility.

  Why Not C (Test development): Test environments are used for development, not running legacy applications.

  Core 1 (220-1101), Section 4.2, virtualization concepts.

• Question 627:

  Which of the following virtualization technologies allows Linux and Windows operating system to run concurrently?

  A. Test environment
  B. Sandbox
  C. Legacy OS
  D. Cross-platform
  D. Cross-platform

• Question 628:

  A user's computer frequently freezes and requires multiple hard restarts to recover functionality. A technician confirms the hardware components have not been recently upgraded or replaced. Which of the following should the technician do first to troubleshoot the issue?

  A. Check the temperature of the CPU.
  B. Update the device driver.
  C. Read the event logs.
  D. Replace the power supply.
  C. Read the event logs.

• Question 629:

  A technician needs to figure out why a laser printer is intermittently not feeding paper to print. The technician verifies the issue by running several copy-and-print tests.

  Which of the following should the technician do next?

  A. Update the printer drivers.
  B. Select the correct paper size.
  C. Clean the pickup rollers.
  D. Replace the toner cartridge.
  C. Clean the pickup rollers.

  ---

  Explanation

  Intermittent paper feeding issues in a laser printer are commonly caused by dirty or worn- out pickup rollers. Cleaning the rollers can restore proper functionality. This aligns with the CompTIA A+ Core 1 objective related to troubleshooting and maintaining printers, specifically resolving paper feeding issues.

• Question 630:

  A technician installed four hard drives in a RAID 5 configuration. After creating the array, the technician is unable to copy files to the array within Windows. Which of the following should the technician do next?

  A. Decrease the number of drives to three.
  B. Partition and format the volume.
  C. Rebuild the array.
  D. Check the hot spare status.
  B. Partition and format the volume.

  ---

  Explanation

  When setting up a RAID array, the raw storage space needs to be partitioned and formatted with a file system before it can be used for storing files. Since the technician has already configured the array, the next logical step is to partition and format the volume within the RAID array to make it accessible and usable within the Windows operating system.
