ITPEC FE Morning April 2022 Question 35
ITPEC FE Morning April 2022 — Question 35 of 80
ARP (Address Resolution Protocol) — resolves IP addresses to MAC addresses on a local network.
ARP sends a broadcast asking "Who has this IP?" and the device with that IP replies with its MAC address.
Why not others:
- (b) ICMP — used for network diagnostics (ping, traceroute), not address resolution
- (c) RARP — reverse: converts MAC → IP (obsolete, replaced by DHCP)
- (d) RIP — a distance-vector routing protocol, unrelated to address resolution
Key rule: ARP = IP → MAC; RARP = MAC → IP.
