CompTIA A+ Certification Exam: Core 2 Sample Questions (Q554-Q559):

NEW QUESTION # 554
A remote user is experiencing issues connecting to a corporate email account on a laptop. The user clicks the internet connection icon and does not recognize the connected Wi-Fi. The help desk technician, who is troubleshooting the issue, assumes this is a rogue access point. Which of the following is the first action the technician should take?

  • A. Restart the wireless adapter.
  • B. Launch the browser to see if it redirects to an unknown site.
  • C. Instruct the user to disconnect the Wi-Fi.
  • D. Instruct the user to run the installed antivirus software.

Answer: C

Explanation:
Instructing the user to disconnect the Wi-Fi is the first action the technician should take if they suspect a rogue access point. A rogue access point is an unauthorized wireless network that could be used to intercept or manipulate network traffic, compromise security, or launch attacks. Disconnecting the Wi-Fi would prevent further exposure or damage to the user's device or data. Restarting the wireless adapter, launching the browser, or running the antivirus software are possible actions to take after disconnecting the Wi-Fi, but they are not as urgent or effective as the first step.

NEW QUESTION # 555
A remote user's smartphone is performing very slowly. The user notices that the performance improves slightly after rebooting but then reverts back to performing slowly. The user also notices that the phone does not get any faster after connecting to the company's corporate guest network. A technician sees that the phone has a large number of applications installed on it. Which of the following is the most likely cause of the issue?

  • A. The user has too many processes running.
  • B. The smartphone has been jailbroken.
  • C. The user is in a poor signal area.
  • D. The smartphone has malware on it.

Answer: A

Explanation:
One of the common reasons for a slow smartphone performance is having too many apps installed and running in the background. These apps consume the device's memory (RAM) and CPU resources, which can affect the speed and responsiveness of the phone. Rebooting the phone can temporarily clear the RAM and stop some background processes, but they may resume after a while. Connecting to a different network does not affect the performance of the phone, unless the network is congested or has a poor signal. The user can improve the phone's performance by uninstalling unused apps, clearing app caches, and restricting background activities12. Malware can also slow down a phone, but it is not the most likely cause in this scenario, as the user does not report any other symptoms of infection, such as pop-ups, battery drain, or data usage spikes3.
Jailbreaking a phone can also affect its performance, but it is not a cause, rather a consequence, of the user's actions. Jailbreaking is the process of removing the manufacturer's restrictions on a phone, which allows the user to install unauthorized apps, customize the system, and access root privileges4. However, jailbreaking also exposes the phone to security risks, voids the warranty, and may cause instability or compatibility issues5.

NEW QUESTION # 556
A technician thinks that a computer on the network has been infected with malware. The technician attempts several times to use a malware removal tool, but the issue persists. Which of the following should the technician do next?

  • A. Reboot the computer into safe mode
  • B. Restore the computer from the last known-good backup
  • C. Purchase a new endpoint protection tool
  • D. Use system recovery to prevent further infection

Answer: A

Explanation:
Detailed
Rebooting the computer into safe mode (Option B) limits the processes and services that run, which can help in isolating and removing persistent malware that might be hiding in normal mode. Safe mode provides a cleaner environment to troubleshoot and remove malware.
Restoring from a backup (Option A) may work but should be considered after attempts to clean the infection.
Purchasing a new endpoint protection tool (Option C) is unnecessary at this stage since existing tools can be run in safe mode.
Using system recovery (Option D) could potentially remove the infection, but it's a more drastic step that may not be necessary yet.

NEW QUESTION # 557
A new employee is having difficulties using a laptop with a docking station The laptop is connected to the docking station, and the laptop is closed. The external monitor works for a few seconds, but then the laptop goes to sleep. Which of the following options should the technician configure in order to fix the Issue?

  • A. Hibernate
  • B. Choose what closing the lid does
  • C. Turn on fast startup
  • D. Sleep/suspend

Answer: B

Explanation:
The correct answer is C. Choose what closing the lid does. This option allows you to configure how the laptop behaves when you close the lid, such as whether it goes to sleep, hibernates, shuts down, or does nothing. To access this option, you can follow these steps :
Go to Settings > System > Power & sleep.
Click on Additional power settings on the right side.
Click on Choose what closing the lid does on the left side.
Under When I close the lid, select Do nothing for both On battery and Plugged in.
Click on Save changes.
This will prevent the laptop from going to sleep when you close the lid while it is connected to the docking station and the external monitor.
Hibernate, sleep/suspend, and turn on fast startup are not the options that should be configured to fix the issue. Hibernate and sleep/suspend are both power-saving modes that allow you to resume your work without losing any data.
However, they also turn off the display and other components of the laptop, which means you will not be able to use the external monitor when the laptop is closed. Turn on fast startup is a feature that reduces the boot time of Windows by saving some system information to a file when you shut down. It does not affect how the laptop behaves when you close the lid .


NEW QUESTION # 558
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. TKIP
  • B. WPA3
  • C. WPS
  • D. WEP

Answer: B

Explanation:
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-in-the-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.
