• Question 402:

  When a user is in the office, the user's mobile phone loads applications and web browses very slowly on a cellular connection. Which of the following is the best way to fix this issue?

  A. Connect to the company's Wi-Fi network.
  B. Change the settings on the phone to connect to a different cellular tower.
  C. Install a cellular repeater at the office for this user.
  D. Update all applications on the phone.
  A. Connect to the company's Wi-Fi network.

  Explanation

  The best way to fix the issue of slow cellular connection in the office is to connect to the company's Wi-Fi network. This will allow the user's mobile phone to access the internet through a faster and more reliable wireless network, instead of relying on the cellular network. Connecting to the Wi-Fi network will also save the user's data usage and battery life. Some of the factors that can affect the cellular connection speed are the distance from the cell tower, the obstructions between the phone and the tower, the network congestion, the network technology, and the features of the phone12. In the office, the user may experience a weak or unstable cellular signal due to the building structure, the location, or the interference from other devices. Therefore, switching to the Wi-Fi network can improve the performance of the phone's applications and web browsing.

• Question 403:

  A Windows computer is experiencing slow performance when the user tries to open programs and files. The user recently installed a new software program from an external website.

  Various websites are being redirected to an unauthorized site, and Task Manager shows the CPU usage is consistently at 100%. Which of the following should the technician do first?

  A. Uninstall the new program.
  B. Check the HOSTS file.
  C. Restore from a previous backup.
  D. Clear the web browser cache.
  A. Uninstall the new program.

  ---

  Explanation

  The symptoms that the user's Windows computer is experiencing suggest that the new software program that the user installed from an external website may be malicious or incompatible with the system. The program may be consuming a lot of CPU resources, slowing down the performance of other programs and files. The program may also be altering the browser settings or the HOSTS file, causing the web redirection to an unauthorized site. The first step that the technician should do is to uninstall the new program from the Control Panel or the Settings app, and then restart the computer. This may resolve the issue and restore the normal functionality of the computer. If the problem persists, the technician may need to perform additional steps, such as scanning for malware, checking the HOSTS file, clearing the web browser cache, or restoring from a previous backup

• Question 405:

  A technician is investigating a workstation that has not received the latest policy changes. Which of the following commands should the technician use to apply the latest domain policy changes?

  A. sfc /scannow
  B. gpupdare /force
  C. chkdsk /y
  D. xcopy Zp
  B. gpupdare /force

  ---

  Explanation

  system files, not to update group policies.

  Option B: gpupdate /forceThis command forces the workstation to reapply all group policies, ensuring that the latest policies are applied immediately. Option C: chkdsk /yThis command checks the integrity of the file system and fixes logical

  file system errors, not to update group policies.

  Option D: xcopy /ZpThis command is used for copying files and directories, not for updating group policies.

  Press Windows key + R to open the Run dialog box, or open the Command Prompt.

  Type mmc and hit Enter. This will open a blank MMC console.

  Click File and then Add/Remove Snap-in.

  In the Add or Remove Snap-ins window, select Local Users and Groups from the Available snap-ins list, and click Add.

  In the Select Computer window, choose Local computer or Another computer, depending on which computer you want to manage, and click Finish. Click OK to close the Add or Remove Snap-ins window. You should now see Local Users and

  Groups in the MMC console.

  Check the startup programs, Unnecessary programs running at startup can slow down the system.

  Option

  C. Back up the data, Important but not the first step for performance troubleshooting.

  Option

  D. Disable the guest account, May prevent future unauthorized use but does not immediately fix the current issue.

  Option

  E. Update the firmware, Firmware updates improve hardware stability but are unlikely to fix a sudden performance drop.

  Option

  F. Reinstall the operating system, A last resort, as it erases data and takes significant time.

  Explanation with Core 2

  References:BitLocker To Go is a feature in Windows that allows for encryption of removable drives to protect sensitive information. Training staff on BitLocker To Go ensures that if a removable drive is lost or stolen, it will be password-protected and encrypted, making the data inaccessible to unauthorized individuals. This aligns with Core 2 objectives related to security measures for data-at-rest encryption and best practices for safeguarding information (CompTIA A+ Core 2 Objective 2.6).
