What is the function of NTP?

• A. To synchronize the clocks of devices on a network
• B. To translate domain names into IP addresses
• C. To encrypt data transmissions
• D. To manage routing tables

Answer: (A)

NTP is about synchronizing clocks across devices on a network. By pulling time from accurate sources (like reference clocks or GPS) and distributing it to clients, it keeps all systems on roughly the same time. This alignment is essential for correctly ordering events in logs, coordinating time-based tasks, and supporting security mechanisms that rely on timestamps. NTP uses a hierarchical structure with time sources and adjusts local clocks to reduce drift, even over imperfect networks. This timing service is distinct from translating names to IPs (DNS), encrypting data (TLS/SSL), or managing routing tables (routing protocols), which serve different purposes.
