• Question 242:

  A technician installs a new printer for a workstation and tries to print a test page, but the page does not print. The technician looks at the print queue and notices that the printer is called 'Generic Printer." Which of the following BEST describes what the technician should do to fix this issue?

  A. Connect the printer with a USB cable rather than over the network.

  B. Install the appropriate printer drivers for the OS.

  C. Install the correct toner in the printer.

  D. Set the printer trays to allow duplex printing

  Correct Answer: B

  The technician should install the appropriate printer drivers for the OS to enable the computer to communicate with the printer. The generic printer name suggests that the drivers are missing or not installed correctly.

• Question 243:

  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.

  Correct Answer: A

  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. References: CompTIA A+ Certification All-in-One uide, Tenth Edition, Chapter 6

• Question 244:

  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

  Correct Answer: BC

  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 245:

  Which of the following would be BEST reason to use a virtual machine as a sandbox?

  A. To test new software in a safe environment

  B. To increase the efficient use of computing resources

  C. To run multiple machines on the same hardware

  D. To have dedicated hardware for a single system

  Correct Answer: A

  The main reason to use a virtual machine as a sandbox is to test new software in a safe environment without risking the integrity of the host operating system. Using a virtual machine enables the testing of software and allows for the isolation of the software from the host system. References: CompTIA A+ Certification Study Guide, Tenth Edition, pg. 409

• Question 246:

  A technician is inspecting a projector that is displaying fuzzy images. Which of the following actions would provide the BEST solution?

  A. Adjusting the lens

  B. Changing the filter

  C. Replacing the video cable

  D. Reseating the lamp

  Correct Answer: A

  Adjusting the lens is the best solution to improve image quality in a projector. The lens can become misaligned over time or during transportation, causing the image to appear fuzzy.

• Question 247:

  A desktop support technician is tasked with upgrading a laptop so that it has the fastest data access possible. Which of the following BEST satisfies this requirement?

  A. mSATASSD

  B. M.2NVMeSSD

  C. 2.5SATASSD

  D. 2.5SASHHD

  Correct Answer: B

  M.2 NVMe SSD provides the fastest data access possible for a laptop. It is a high-performance solid-state drive that connects directly to the motherboard through an M.2 slot.

• Question 248:

  A user creates a support ticket to report a conference room projector that does not work. The user says that even though the provided cables are being used, the projector screen shows the following error message:

  No signal input

  Which of the following describes the FIRST action that should be taken?

  A. Verify that the projector is turned on.

  B. Verify that the user is using an approved OS.

  C. Replace the projector bulb.

  D. Check the video cable and replace it if necessary.

  Correct Answer: D

  The most common reasons you may be seeing the "No Signal" message:

  The projector and the source device are not connected correctly. The first action should be to check the video cable and replace it if necessary, as the error message suggests that the projector is not receiving a signal from the laptop.

  Verifying that the projector is turned on and checking the bulb would come after verifying the video cable.

• Question 249:

  A technician is troubleshooting intermittent fuzzy video on a computer using a VGA to DisplayPort adapter to connect to a monitor. The monitor with a VGA connector was previously working tine for another user. The technician replaces the adapter; however, the issue persists. Which of the following should the technician do NEXT?

  A. Use another brand of VGA lo DisplayPort adapter.

  B. Research the issue further and formulate a new hypothesis to test.

  C. Ask the user additional clarifying questions regarding the issue.

  D. Document the action taken and the outcome.

  Correct Answer: C

  https://spryzensecurity.medium.com/what-is-troubleshooting-methodology-40cec6b6494 The technician should ask the user additional clarifying questions regarding the issue. This will help to identify any other potential causes of the issue, such as software configuration or compatibility issues, before attempting any further troubleshooting steps.

• Question 250:

  A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the cable mediums would be the MOST cost effective without sacrificing system performance?

  A. Coaxial

  B. Shielded Cat 6

  C. Plenum Cat 5e

  D. Multimode fiber

  Correct Answer: B

  In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable's conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.
