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.
