Which option correctly names the ARP command?

Which option correctly names the ARP command?

• A. ARP
• B. The arp command
• C. Address Resolution Protocol
• D. The network route

Answer: (B)

The concept being tested is how we name a command-line tool versus the protocol it implements. The ARP command is the actual program you run in the shell, typically invoked as arp, which is why it’s correctly referred to as “the arp command.” This naming shows you’re talking about the utility itself, not the protocol or its full name. ARP stands for Address Resolution Protocol, so that phrase names the mechanism, not the executable. The network route is unrelated to ARP. The arp command is used to view and modify the ARP cache on the local machine, linking IP addresses to MAC addresses as needed.
