LX0-104 · Question #38
Which of the following is observed and corrected by a NTP client?
The correct answer is B. The skew in time between the system clock and the reference clock.. An NTP client observes and corrects the time difference, or skew, between its local system clock and a remote, authoritative reference clock. This process ensures the client's system time remains accurate and synchronized.

Why each option
An NTP client observes and corrects the time difference, or skew, between its local system clock and a remote, authoritative reference clock. This process ensures the client's system time remains accurate and synchronized.
The skew in time between the system clock (software clock) and the hardware clock (RTC) is typically managed by operating system utilities like `hwclock`, not directly by NTP.
The Network Time Protocol (NTP) client's primary function is to synchronize its local system clock with time provided by NTP servers, which act as reference clocks. It continuously monitors and adjusts the system clock to minimize any drift or skew from the reference time.
NTP synchronizes time, not time zones. Time zone settings are configured separately on the local system and affect how the synchronized UTC time is displayed locally.
NTP synchronizes Coordinated Universal Time (UTC); adjustments for Daylight Saving Time are handled by the local operating system based on its time zone configuration, not by NTP itself.
