A user’s computer is displaying a black screen. The technician restarts the computer, but the OS still does not load. The technician discovers the OS was patched the previous evening. Which of the following should the technician attempt NEXT?
-
Reboot into safe mode and roll back the updates
-
Repair the Windows Registry
-
Disable Windows services and applications
-
Configure boot options in the BIOS
Correct Answer
A. Reboot into safe mode and roll back the updatesExplanation
After restarting the computer and finding that the OS still does not load, the technician should attempt to reboot into safe mode and roll back the updates. This is because the black screen issue could be caused by a recent patch or update that is incompatible with the system. By booting into safe mode, the technician can access the system with minimal drivers and services, allowing them to uninstall or roll back the problematic update. This can potentially resolve the issue and allow the OS to load properly. Repairing the Windows Registry, disabling Windows services and applications, or configuring boot options in the BIOS may not directly address the issue of the OS not loading after a recent update.Rate this question:

A company brings in contractors several times a year to perform inventory, and the contractors use company-supplied laptops. The company’s security policy states that once the inventory is completed, the contractors should not be able to log in to the laptops until the next inventory. Which of the following BEST enforces this policy?
-
Delete the user accounts
-
Disable the user accounts
-
Restrict the user accounts
-
Reset the user accounts
Correct Answer
A. Disable the user accountsExplanation
Disabling the user accounts would be the best way to enforce the company's security policy.

-
Telnet
-
SSH
-
RDP
-

This will make it more difficult for the nearby company to connect and use the wireless connection without permission. By reducing the power levels, the network signal will be weaker and have a shorter range, making it more localized to the small business premises.Rate this question:
