What application is automatically executed when an IP address must be matched to a MAC address?

A	ARP
B	RARP
C	DHCP
D	DNS

Explanation:

Detailed explanation-1: -The ARP Request’s destination was the broadcast MAC address ( ffff. ffff. ffff ). The ARP Request existed for the purpose of resolving Host B’s MAC address, hence the target is Host B.

Detailed explanation-2: -ARP, or the Address Resolution Protocol, works by mapping the IPv4 address to a destination MAC address. The host knows the destination IPv4 address and uses ARP to resolve the corresponding destination MAC address.

Detailed explanation-3: -Address Resolution Protocol (ARP) is the method for finding a host’s Link Layer (MAC) address when only its IP address is known. The ARP table is used to maintain a correlation between each MAC address and its corresponding IP address. The ARP table can be manually entered by the user.
