CCNA – Show Command Questions
The “Age” field in the “show ip arp” command is the age in minutes of the cache entry.
A hyphen (-) means the address is local so in this case 192.168.1.1 & 192.168.3.1 are
local to this router -> B is correct.
Note: The “Age 0″ means that the address was cached less than 1 minute ago.
