ITPEC FE Morning April 2023 — Question 34 of 80

NTP (Network Time Protocol) — identify the protocol for clock synchronization.

  • NTP syncs clocks between servers and clients in a TCP/IP network
  • Uses UDP port 123
  • Ensures consistent timestamps across distributed systems

Why not others:
- (a) ARP — resolves IP addresses to MAC addresses, unrelated to time

- (b) ICMP — network diagnostics (ping, traceroute), not clock sync

- (d) RIP — a routing protocol that determines packet paths between networks

Key rule: "Match clocks" = NTP. It is the standard time synchronization protocol in TCP/IP networks.
