CompTIA SK0-005 Exam - Topic 2 Question 80 Discussion
Topic #: 2
An administrator is receiving reports that users in a remote office are unable to log in to the domain. The network appears to be up between the sites, which are in different states. Which of the following is the most likely cause of the issue?
A misconfiguredNTP (Network Time Protocol)on the client side can cause authentication issues because Active Directory relies on accurate time synchronization between clients and domain controllers for security purposes. If the clocks are out of sync, even by a few minutes, it can prevent users from authenticating to the domain.
NTP misconfiguration (Answer B):If the client machines have incorrect time settings, it can disrupt Kerberos-based authentication, which is time-sensitive.
Locked user accounts (Option A):While it can prevent login, it would affect individual users rather than a whole office.
MFA (Option C):Multi-factor authentication not working would typically cause a login issue but is less likely across an entire remote office.
Wrong time zone (Option D):While incorrect time zones can cause confusion, they usually don't prevent logins as long as the NTP server synchronizes the actual time correctly.
