Question
Which of the following protocol is used for discovering
link layer address or MAC address, associated with a given internet layer address?Solution
Why this is correct:
ARP resolves an IPv4 address (network-layer) to its corresponding MAC address (link-layer) on a local network. When a host wants to send an IP packet on Ethernet, it uses ARP to find the destination MAC. Why the others are wrong:
- 1 (HTTP): Application-layer web protocol.
- 3 (FTP): Application-layer file transfer protocol.
- 4 (RSVP): Resource Reservation Protocol — used for reserving resources for QoS, not address resolution.
