CompTIA 220-1101 Online Questions & Answers

• Question 861:

  A technician is selecting RAM for a new high-end workstation. The motherboard has eight slots that support DDR5 memory. Which of the following should the technician do to optimize performance?

  A. Use the minimum number of modules.
  B. Increase the virtual RAM.
  C. Increase memory timings.
  D. Utilize all channels.
  D. Utilize all channels.

  ---

  Explanation

  The best option that the technician should do to optimize performance is

  D. Utilize all channels. This option means that the technician should install the RAM modules in a way that maximizes the number of memory channels that are used by the motherboard. Memory channels are pathways that connect the memory controller to the RAM modules, and they allow data to be transferred between them. The more memory channels that are used, the higher the memory bandwidth and performance1. DDR5 memory supports up to eight memory channels per module, which is twice as many as DDR42. However, not all motherboards can support eight channels per module, and some may only support four or two channels per module. Therefore, the technician should check the motherboard specifications and manual to determine how many memory channels it supports and how to install the RAM modules accordingly. For example, if the motherboard supports four channels per module, then the technician should install four RAM modules in slots 1, 3, 5, and 7 to use all 16 available channels. If the motherboard supports two channels per module, then the technician should install eight RAM modules in all slots to use all 16 available channels. If the technician installs fewer modules than the number of slots, then some channels will be left unused and the performance will be lower1.

• Question 862:

  A technician receives an alert indicating all VMs are down. After some troubleshooting, the technician discovers the network is out of space. To resolve the issue, the technician decides to add more space. Which of the following network types will the technician be working with?

  A. SCSI
  B. NAC
  C. SAN
  D. WISP
  C. SAN

  ---

  Explanation

  A storage area network (SAN) is the type of network that the technician will be working with when adding more space to resolve the issue of all VMs being down due to the network being out of space. A SAN is a network that provides access to consolidated and block-level data storage, which can be used for virtualization and backup purposes. SCSI is a type of interface that connects devices such as hard drives and optical drives to a computer. NAC is a type of security solution that controls access to a network based on policies and device compliance. WISP is a type of internet service provider that delivers wireless broadband access over long distances.

• Question 864:

  A technician recently discovered me root cause of an application error that several users have been experiencing. The technician updated the configurations on the affected machines and verified full functionality was restored for all users, which of the following actions should the technician perform NEXT?

  A. Write a knowledge base article in the ticketing software to expedite future Incidents.
  B. Submit a bug report to the developer of the application, along with the steps taken to resolve the Issue.
  C. Work with the developer to proactively collect the application logs to identify future errors of this type.
  D. Send an email communication to the company about the issue and the steps taken to resolve it.
  A. Write a knowledge base article in the ticketing software to expedite future Incidents.

  ---

  Explanation

  CompTIA 6-Step Troubleshooting Process:

  1.Identify the problem.

  2.Establish a theory of probably cause. (Question the obvious)

  3.Test the theory to determine cause.

  4.Establish a plan of action to resolve the problem and implement the solution.

  5.Verify full system functionality and if applicable implement preventative measures.

  6.Document findings, actions, and outcomes. Writing a knowledge base article in the ticketing software would help document the root cause of the application error and the steps taken to resolve it, which can help other technicians resolve similar issues in the future. This is an example of knowledge management best practices.

• Question 865:

  When a user first turns on a PC, the performance is fine, but the PC becomes slower the longer it is used. The PC is also experiencing random system crashes.

  Which of the following is most likely failing?

  A. CMOS battery
  B. Power supply
  C. Video card
  D. System memory
  B. Power supply

  ---

  Explanation

  A failing power supply can cause random system crashes and degraded performance as it struggles to maintain a consistent voltage, especially as the system demands increase over time. The CMOS battery only affects system time and settings, while the video card typically causes display issues rather than system-wide crashes. System memory issues often result in specific errors or performance issues rather than gradual slowdowns. CompTIA A+ Core 1 objectives highlight troubleshooting power supply issues as part of hardware and system maintenance.

• Question 866:

  A technician just finished assembling a new PC for a client. Upon POST, the device presents an unspecified beep code and turns off automatically after five seconds. The technician double-checks the bill of materials for the new build and confirms all items have been installed. Which of the following should the technician do NEXT?

  A. Ensure thermal paste is being used on the CPU.
  B. Check to make sure that any video cards have auxiliary power cabling connected.
  C. Verify the header panel connector is properly connected.
  D. Spot-check that the I/O shield for the motherboard is properly installed.
  C. Verify the header panel connector is properly connected.

  ---

  Explanation

  The technician should verify the header panel connector is properly connected. A beep code is a diagnostic tool used by motherboards to indicate issues with hardware components. This beep code may be indicating an issue with the connection between the motherboard and the case's header panel connector. This connector is responsible for providing power to the system and any connected peripherals. Therefore, the technician should verify the connection is secure and properly connected before attempting any other troubleshooting steps.

• Question 867:

  A computer that contains critical data has not been backed up and will not boot past a S A R T, error that indicates imminent hard disk failure. Which of the following actions should the technician take FIRST?

  A. Run diagnostics on the faulty hard drive using a boot disk
  B. immediately replace the hard drive generating the SMART error
  C. Turn off S M A R T, monitoring in the computer's BIOS settings
  D. Attempt to boot the operating system in safe mode
  A. Run diagnostics on the faulty hard drive using a boot disk

  ---

  Explanation

  The technician should run diagnostics on the faulty hard drive using a boot disk first when a computer that contains critical data has not been backed up and will not boot past a S M A R T. error that indicates imminent hard disk failure.

• Question 868:

  An integrated webcam on a user's laptop broke, so a technician installed a temporary, external webcam. Since the external webcam installation, other users can only see part of the user's face during videoconferences. Which of the following BEST describes the reason for this issue?

  A. The webcam is not on a level surface.
  B. The webcam driver should be updated.
  C. The webcam is plugged into the wrong USB port.
  D. The webcam is not compatible with the OS.
  A. The webcam is not on a level surface.

  ---

  Explanation

  The most likely reason for the issue is that the webcam is not on a level surface, which causes the camera angle to be distorted. The user should adjust the position of the webcam so that it is aligned with the laptop screen and captures the user's face fully. The other options are not relevant to this issue, as they would not affect the camera angle or visibility of the user's face. Verified
