- A. Isolate the machine from the network.
- B. Disable unused ports.
- C. Scan the system for hidden files.
- D. Reconfigure the firewall.
- E. Install antivirus software.

Isolating the machine can be done by disconnecting the network cable, disabling the wireless adapter, or blocking the network traffic with a firewall.
NEW QUESTION # 163
An Android user contacts the help desk because a company smartphone failed to complete a tethered OS update A technician determines there are no error messages on the device Which of the following should the technician do NEXT?
- A. Confirm a strong internet connection is available using Wi-Fi or cellular data
- B. Check if the battery is sufficiently charged
- C. Determine if the device has adequate storage available.
- D. Verify all third-party applications are disabled
Answer: B
Explanation:
Since there are no error messages on the device, the technician should check if the battery is sufficiently charged1 If the battery is low, the device may not have enough power to complete the update2 In this scenario, the technician has already determined that there are no error messages on the device. The next best step would be to check if the battery is sufficiently charged. If the battery is low, it could be preventing the device from completing the update process.
Verifying that third-party applications are disabled, determining if the device has adequate storage available, and confirming a strong internet connection are all important steps in troubleshooting issues with mobile devices. However, since the problem in this scenario is related to a failed OS update, it is important to first check the battery level before proceeding with further troubleshooting steps.

Which of the following is the best reason for sandbox testing in change management?
- A. To determine the affected systems
- B. To select a change owner
- C. To obtain end-user acceptance
- D. To evaluate the change before deployment
Answer: D
Explanation:
Sandbox testing is a method of testing changes in a simulated environment that mimics the real one, without affecting the actual production system. Sandbox testing is useful for change management because it allows the testers to evaluate the change before deployment, and ensure that it works as intended, does not cause any errors or conflicts, and meets the requirements and expectations of the stakeholders. Sandbox testing also helps to protect the investment in the existing system, as it reduces the risk of introducing bugs or breaking functionality that could harm the customer experience or the business operations. Sandbox testing also gives the testers more control over the customer experience, as they can experiment with different scenarios and configurations, and optimize the change for the best possible outcome.

NEW QUESTION # 176
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. Enable the microphone under Windows Privacy settings to allow desktop applications to access it.
- B. Remove the microphone from the USB hub and plug it directly into a USB port on the PC.
- C. Replace the USB microphone with one that uses a traditional 3.5mm plug.
- D. Delete the microphone from Device Manager and scan for new hardware,
Answer: A
Explanation:
Explanation
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.

- A. Place components on an ESD mat.
- B. Place the PC on a grounded workbench.
- C. Put on an ESD strap
- D. Disconnect the power before servicing the PC.

The first step a technician should take when troubleshooting a computer with a suspected short in the power supply is B.
Disconnect the power before servicing the PC. This is to prevent any electrical shock or damage to the components. A power supply can be dangerous even when unplugged, as capacitors can maintain a line voltage charge for a long time1. Therefore, it is important to disconnect the power cord and press the power button to discharge any residual power before opening the case2. The other steps are also important for safety and proper diagnosis, but they should be done after disconnecting the power.
NEW QUESTION # 180
A corporate smartphone was stored for five months after setup. During this time, the company did not have any system updates. When the phone is turned on, an application runs, but it crashes intermittently. Which of the following should a technician do next?
- A. Clear the cache.
- B. Reinstall the application.
- C. Restart the phone.
- D. Reimage the OS.
Answer: B
Explanation:
Explanation
Reinstalling the application is the best option to fix the intermittent crashing of the application on the corporate smartphone. Reinstalling the application will ensure that the latest version of the app is installed, which may have bug fixes and compatibility updates that can resolve the crashing issue. Reinstalling the app will also clear any corrupted or outdated data or cache that may cause the app to malfunction.
The other options are not as effective or appropriate as reinstalling the app. Restarting the phone may temporarily fix the issue, but it will not address the root cause of the app crashing, which may be related to the app itself or its data. Reimaging the OS is a drastic and unnecessary measure that will erase all the data and settings on the phone and restore it to its factory state. This will also remove all the other apps and files that may be important for the corporate use of the phone. Clearing the cache may help to free up some space and improve the performance of the app, but it will not update the app or fix any bugs that may cause the app to crash.
