What must be adjusted on a workstation if an invalid certificate error occurs when visiting a secure website?

• A. Date and time
• B. UEFI boot mode
• C. Logon times
• D. User access control

Answer: (A)

An invalid certificate error when visiting a secure website often indicates that the system's date and time settings are incorrect. Digital certificates used for securing communications have a validity period defined by a start and end date. If the date and time on a workstation are not accurate, the system may interpret valid certificates as expired or not yet valid, leading to security warnings. Ensuring that the date and time are correctly set allows the workstation to validate certificates against their expected validity periods. This is a common issue that can easily be resolved by adjusting the system clock. By synchronizing the date and time to an accurate source, users should be able to navigate to secure websites without encountering these errors.
