A technician wants to mitigate unauthorized data access if a computer is lost or stolen. Which of the following features should the technician enable?
Correct Answer:
C
BitLocker is a Windows security feature that provides encryption for entire volumes, addressing the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned devices1. BitLocker helps mitigate unauthorized data access by enhancing file and system protections, rendering data inaccessible when BitLocker-protected devices are decommissioned or recycled1. Network share, Group Policy, and Static IP are not features that can prevent unauthorized data access if a computer is lost or stolen.

A user is unable to access a website, which is widely used across the organization, and receives the following error message:
The security certificate presented by this website has expired or is not yet valid.
The technician confirms the website works when accessing it from another computer but not from the user's computer. Which of the following should the technician perform NEXT to troubleshoot the issue?
Correct Answer:
D
The error message indicates that the security certificate presented by the website has either expired or is not yet valid. This can happen if the computer's clock has the wrong date or time, as SSL/TLS certificates have a specific validity period. If the clock is off by too much, it may cause the certificate to fail to validate. Therefore, the technician should check the computer's date and time and ensure that they are correct.
