• Question 131:

  A technician is troubleshooting a PC that has been experiencing random system crashes. The technician has already checked the hard drive and the RAM, and both were in good working order. Which of the following steps should the technician take next to troubleshoot the system crashes?

  A. Test the fan speed.
  B. Disable the USB ports
  C. Replace the PSU
  D. Decrease the RAM timings.
  C. Replace the PSU

  ---

  Explanation

  A PSU (power supply unit) is a component that converts the AC power from the wall outlet into DC power that the PC components can use. A faulty or failing PSU can cause random system crashes, as well as other problems such as noise, overheating, or no power at all. A PSU can fail due to various reasons, such as age, dust, power surges, or poor quality. To troubleshoot a PSU, the technician can use a multimeter to measure the voltage output of the PSU connectors. The voltage should be within the acceptable range of the specifications. For example, the 12V rail should be between 11.4V and 12.6V. If the voltage is too low or too high, the PSU is likely defective and needs to be replaced. Alternatively, the technician can try swapping the PSU with a known good one and see if the system crashes persist. If the system works fine with a different PSU, then the original PSU is the problem and should be replaced. The other options are not likely to fix the random system crashes. Testing the fan speed may help to diagnose overheating issues, but it is not related to the PSU. Disabling the USB ports may help to eliminate potential conflicts with USB devices, but it is not related to the PSU. Decreasing the RAM timings may help to improve performance and stability, but it is not related to the PSU.

• Question 132:

  In a SOHO environment, a user wants to make sensitive, scanned documents available to other users on the domain. The logs need to indicate who accessed the documents and at what time they were accessed. Which of the following settings should a technician set up on the MFP device?

  A. Scan to email
  B. ADF tray
  C. PCL
  D. SMB share
  D. SMB share

  ---

  Explanation

  The correct answer is

  D. SMB share.

  SMB stands for Server Message Block, which is a network protocol that allows file and printer sharing among different devices on a local area network (LAN). An SMB share is a folder or drive that is shared using the SMB protocol and can be accessed by authorized users on the network. An MFP device is a multifunction printer that can perform multiple tasks, such as printing, scanning, copying, and faxing. In a SOHO (small office/home office) environment, a user who wants to make sensitive, scanned documents available to other users on the domain can set up an SMB share on the MFP device. This way, the user can scan the documents to the SMB share and grant access permissions to the other users who need to view or edit them. The SMB share can also enable logging, which can record who accessed the documents and at what time they were accessed . The other options are not the best settings for this scenario. Scan to email is a feature that allows the user to scan a document and send it as an email attachment to a recipient. This option may not be secure or convenient for sharing sensitive documents with multiple users on the domain. ADF tray stands for automatic document feeder tray, which is a component of an MFP device that can feed multiple pages of a document into the scanner or copier without manual intervention. This option is not related to sharing or logging scanned documents. PCL stands for Printer Command Language, which is a page description language that controls the layout and printing of documents. This option is not related to sharing or logging scanned documents either.

• Question 134:

  A technician is troubleshooting a computer that has a loud system fan and randomly freezes and reboots. Which of the following is the most likely cause of these issues?

  A. Failing hard drive
  B. Defective power supply
  C. Incompatible hardware
  D. Overheating processor
  D. Overheating processor

  ---

  Explanation

  An overheating processor is the most likely cause of a computer that has a loud system fan and randomly freezes and reboots. A processor generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the processor or cause it to malfunction. A loud system fan indicates that the fan is working harder to cool down the processor, but it may not be enough to prevent overheating. A computer that freezes and reboots randomly is a common symptom of an overheating processor, as the system tries to protect itself from further damage by shutting down or restarting. The other options are not as likely to cause these issues. A failing hard drive may cause data loss, corruption, or slow performance, but it does not affect the system fan or the processor temperature. A defective power supply may cause the computer to shut down unexpectedly, but it does not cause the system fan to be loud or the processor to overheat. Incompatible hardware may cause the computer to fail to boot, display errors, or crash, but it does not cause the system fan to be loud or the processor to overheat. To troubleshoot and resolve an overheating processor issue, the technician should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the processor if necessary. The technician should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.

  A. RAID
  B. SSD
  C. S.M.A.R.T
  D. HDD
  D. HDD

  ---

  Explanation

  The clicking sound is the sound of a damaged disk in the HDD A clicking sound from a hard disk drive typically indicates a mechanical failure, such as the read/write head hitting a physical obstruction or a problem with the disk motor. This can cause the drive to fail to initialize or not be recognized by the system during booting.

• Question 136:

  After a company upgraded its network infrastructure, a user's desktop has been experiencing slow network speeds. Which of the following should a technician do first to improve desktops connectivity performance?

  A. Update the NIC drivers
  B. update the BIOS firmware.
  C. Replace the motherboard
  D. Replace the patch cable
  D. Replace the patch cable

  ---

  Explanation

  The technician should replace the patch cable that connects the desktop to the network switch or outlet. The patch cable may be damaged or incompatible with the upgraded network infrastructure, which can cause slow network speeds. According to the CompTIA Core1 objectives, one of the common symptoms of a bad cable is slow transfer speeds. A research paper on network performance also states that cable quality and length can affect network speed.

• Question 138:

  Which of the following server roles does RADIUS perform?

  A. DNS
  B. AAA
  C. Mail server
  D. Syslog
  B. AAA

  ---

  Explanation

  AAA stands for Authentication, Authorization, and Accounting, and it is a framework that provides security services for network access control. Authentication verifies the identity of a user or device that requests access to a network resource. Authorization determines what level of access or privileges are granted to a user or device based on their identity or role. Accounting tracks and records the usage of network resources by users or devices for billing or auditing purposes. RADIUS (Remote Authentication Dial-In User Service) is a protocol that implements AAA functions by communicating with a central server that stores user credentials and policies.

• Question 139:

  Which of the following is the most likely use case for client-side virtualization for a software developer?

  A. Increasing the application performance
  B. Enhancing the security of physical machines
  C. Reducing the operational costs
  D. Testing on different operating systems
  D. Testing on different operating systems

  ---

  Explanation

  The most likely use case for client-side virtualization for a software developer is

  D. Testing on different operating systems. Client-side virtualization is a type of virtualization that allows a single physical machine, such as a laptop or a desktop, to run multiple virtual machines, each with its own operating system and applications. Client-side virtualization can provide several benefits, such as:

  Increasing the application performance by allocating more resources to the virtual machine that runs the application.

  Enhancing the security of physical machines by isolating the virtual machines from each other and from the host machine, and preventing malware or attacks from spreading or affecting the data. Reducing the operational costs by consolidating multiple physical machines into one, and saving on hardware, software, and energy expenses. However, the most likely use case for client-side virtualization for a software developer is testing on different operating systems. This means that a software developer can use client-side virtualization to create and run different virtual machines with different operating systems, such as Windows, Linux, or Mac OS, and test how their software works and performs on each of them. This can help the software developer to ensure the compatibility, functionality, and quality of their software across different platforms and environments. It can also help the software developer to debug and fix any issues or errors that may arise on different operating systems.

• Question 140:

  A customer is using a satellite internet connection that is experiencing slowness. A technician notices high latency while pinging, but the download test is performing perfectly with very good download speeds. Which of the following represents the NEXT action the technician should perform?

  A. Restart the modem and run an online internet connection and speed diagnostic tool.
  B. Guide the customer on how to upgrade the internet plan with the provider in order to improve latency.
  C. Explain to the customer this is not an issue; this situation is normal for this type of internet connection.
  D. Replace the modem because it is not working correctly based on the test result.
  A. Restart the modem and run an online internet connection and speed diagnostic tool.

  ---

  Explanation

  The technician should restart the modem and run an online internet connection and speed diagnostic tool1. High latency is a common issue with satellite internet connections, and it can cause slow internet speeds2. Restarting the modem can help to resolve the issue1. The technician should also run an online internet connection and speed diagnostic tool to check the connection and speed1. Guiding the customer on how to upgrade the internet plan with the provider in order to improve latency is not likely to be the correct option2. High latency while pinging can indicate a problem with the modem or the connection between the modem and the satellite. Restarting the modem can often resolve connectivity issues. Running an online internet connection and speed diagnostic tool can help identify any other issues with the connection. Upgrading the internet plan may not resolve latency issues and may not be necessary if the download test is performing perfectly with very good download speeds. High latency is not normal for satellite internet connections, so replacing the modem based on this one test result is premature.
