Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

While arp -a is common in Windows and many Unix-like systems, the standard Linux arp utility (from net-tools) displays the table when run without arguments or with specific flags. However, arp -a is the standard way to view the cache. The stored answer 4164 is technically correct as the command name.
