• Question 271:

  A suite of security applications was installed a few days ago on a user's home computer.

  The user reports that the computer has been running slowly since the installation.

  The user notices the hard drive activity light is constantly solid.

  Which of the following should be checked FIRST?

  A. Services in Control Panel to check for overutilization

  B. Performance Monitor to check for resource utilization

  C. System File Checker to check for modified Windows files

  D. Event Viewer to identify errors

  Correct Answer: C

  System File Checker to check for modified Windows files. System File Checker (SFC) is a Windows utility that can be used to scan for and restore corrupt Windows system files. SFC can be used to detect and fix any modified or corrupted system files on a computer, and thus should be checked first when a user reports that their computer has been running slowly since the installation of security applications [1][2]. By checking SFC, any modified or corrupted system files can be identified and fixed, potentially improving the overall performance of the computer.

• Question 272:

  A technician connects an additional monitor to a PC using a USB port. The original HDMI monitor is mounted to the left of the new monitor. When moving the mouse to the right from the original monitor to the new monitor, the mouse stops at the end of the screen on the original monitor.

  Which of the following will allow the mouse to correctly move to the new monitor?

  A. Rearranging the monitor's position in display settings

  B. Swapping the cables for the monitors

  C. Using the Ctrl+AIt+> to correct the display orientation

  D. Updating the display drivers for the video card

  Correct Answer: B

  The correct answer is B. Swapping the cables for the monitors. When the second monitor is connected with the HDMI port, it is necessary to swap the cables for the monitors so that the mouse can move from the original monitor to the new monitor. This is because the HDMI port is designed to only support one monitor, and the mouse will not be able to move from one to the other without the cables being swapped. According to CompTIA A+ Core 2 documents, "When connecting multiple displays to a system, the cables used to connect the displays must be swapped between the displays. For example, if a monitor is connected to a system using a VGA cable, the VGA cable must be moved to the next display to allow the mouse to move between the two displays."

• Question 273:

  A technician has been asked to set up a new wireless router with the best possible security. Which of the following should the technician implement?

  A. WPS

  B. TKIP

  C. WPA3

  D. WEP

  Correct Answer: C

  WPA3 (Wi-Fi Protected Access version 3) is the latest version of Wi-Fi security and offers the highest level of protection available. It is designed to protect against brute force password attempts and protect against eavesdropping and man-inthe-middle attacks. WPA3 also supports the use of stronger encryption algorithms, such as the Advanced Encryption Standard (AES), which provides additional protection for wireless networks. WPA3 should be implemented in order to ensure the best possible security for the new wireless router.

• Question 275:

  A technician is troubleshooting a lack of outgoing audio on a third-party Windows 10 VoIP application, The PC uses a USB microphone connected to a powered hub. The technician verifies the microphone works on the PC using Voice Recorder.

  Which of the following should the technician do to solve the issue?

  A. Remove the microphone from the USB hub and plug it directly into a USB port on the PC.

  B. Enable the microphone under Windows Privacy settings to allow desktop applications to access it.

  C. Delete the microphone from Device Manager and scan for new hardware,

  D. Replace the USB microphone with one that uses a traditional 3.5mm plug.

  Correct Answer: B

  In Windows 10, there are privacy settings that control access to certain devices, such as microphones, cameras, and other input devices. If the microphone is not enabled under these privacy settings, the VoIP application may not have access to it, causing a lack of outgoing audio. The technician can go to the Windows 10 Settings menu, select the Privacy submenu, and under App permissions, select Microphone. The technician should then turn on the toggle switch for the VoIP application to allow it to access the microphone. Removing the microphone from the USB hub and plugging it directly into a USB port on the PC may or may not solve the issue, as the issue could be related to the privacy settings. Deleting the microphone from Device Manager and scanning for new hardware may also not solve the issue, as the issue could be related to the privacy settings. Replacing the USB microphone with one that uses a traditional 3.5mm plug is not recommended, as it would require purchasing a new microphone and may not solve the issue.

• Question 276:

  An analyst needs GUI access to server software running on a macOS server. Which of the following options provides the BEST way for the analyst to access the macOS server from the Windows workstation?

  A. RDP through RD Gateway

  B. Apple Remote Desktop

  C. SSH access with SSH keys

  D. VNC with username and password

  Correct Answer: B

  Apple Remote Desktop is a remote access solution that allows a user to access and control another macOS computer from their Windows workstation. It provides a graphical user interface so that the analyst can easily access the server software running on the macOS server. Apple Remote Desktop also supports file transfers, so the analyst can easily transfer files between the two computers. Additionally, Apple Remote Desktop supports encryption, so data is secure during transmission.

• Question 277:

  The findings from a security audit indicate the risk of data loss from lost or stolen laptops is high. The company wants to reduce this risk with minimal impact to users who want to use their laptops when not on the network. Which of the following would BEST reduce this risk for Windows laptop users?

  A. Requiring strong passwords

  B. Disabling cached credentials

  C. Requiring MFA to sign on

  D. Enabling BitLocker on all hard drives

  Correct Answer: D

  BitLocker is a disk encryption tool that can be used to encrypt the hard drive of a Windows laptop. This will protect the data stored on the drive in the event that the laptop is lost or stolen, and will help to reduce the risk of data loss. Additionally, BitLocker can be configured to require a PIN or other authentication in order to unlock the drive, providing an additional layer of security.

• Question 278:

  A help desk technician runs the following script: Inventory.py. The technician receives the following error message:

  How do you want to Open this file?

  Which of the following is the MOST likely reason this script is unable to run?

  A. Scripts are not permitted to run.

  B. The script was not built for Windows.

  C. The script requires administrator privileges,

  D. The runtime environment is not installed.

  Correct Answer: D

  The error message is indicating that the script is not associated with any program on the computer that can open and run it. This means that the script requires a runtime environment, such as Python, to be installed in order for it to execute properly. Without the appropriate runtime environment, the script will not be able to run.

• Question 279:

  A field technician applied a Group Policy setting to all the workstations in the network. This setting forced the workstations to use a specific SNTP server. Users are unable to log in now. Which of the following is the MOST likely cause of this issue?

  A. The SNTP server is offline.

  B. A user changed the time zone on a local machine.

  C. The Group Policy setting has disrupted domain authentication on the system,

  D. The workstations and the authentication server have a system clock difference.

  Correct Answer: D

  The workstations and the authentication server have a system clock difference. If a Group Policy setting is applied that forces the workstations to use a specific SNTP server, but the system clock on the workstations and the authentication server are out of sync, then this can cause authentication issues and users will be unable to log in. In this case, the most likely cause of the issue is a difference in system clocks and the technician should ensure that the clocks on the workstations and the authentication server are in sync.

• Question 280:

  A technician is reimaging a desktop PC. The technician connects the PC to the network and powers it on. The technician attempts to boot the computer via the NIC to image the computer, but this method does not work.

  Which of the following is the MOST likely reason the computer is unable to boot into the imaging system via the network?

  A. The computer's CMOS battery failed.

  B. The computer's NIC is faulty.

  C. The PXE boot option has not been enabled

  D. The Ethernet cable the technician is using to connect the desktop to the network is faulty.

  Correct Answer: C

  The most likely reason the computer is unable to boot into the imaging system via the network is that the PXE boot option has not been enabled. PXE (Preboot Execution Environment) is an environment that allows computers to boot up over the network, instead of from a local disk. In order for this to work, the PXE boot option must be enabled in the computer's BIOS settings. As stated in the CompTIA A+ Core 2 exam objectives, technicians should know how to enable PXE in BIOS to enable network booting on a computer.
