What is typically required for a polling NTP client to synchronize time?

• A. Periodic broadcasts
• B. Manual updates
• C. Scheduled requests
• D. Continuous feedback

Answer: (C)

For a polling NTP (Network Time Protocol) client to effectively synchronize time, it typically relies on scheduled requests to NTP servers. This method allows the client to periodically send out requests for the current time, at specified intervals, ensuring that the client can adjust its time to match the accurate time provided by the NTP servers. Using scheduled requests allows for a structured approach to synchronization, where the client knows when to check in with the time source. This periodic polling is crucial because it enables the client to keep its clock in sync over regular intervals, accounting for any drift that may occur due to clock inaccuracies. In contrast, other methods such as manual updates or continuous feedback can be less reliable or impractical for regular time synchronization needs. Periodic broadcasts do not apply in this context as NTP primarily functions on a request-response model rather than a broadcast-based synchronization process. Therefore, the requirement for scheduled requests is foundational to the proper functioning of a polling NTP client in maintaining accurate time synchronization.
