If the command arp -f is run, which file will be read by default?
A.
/etc/hosts
B.
/etc/ethers
C.
/etc/arp.conf
D.
/etc/networks
E.
/var/cache/arp
Explanation:
from the man pages:
arp – manipulate the system ARP cache
-f filename, –file filename
Similar to the -s option, only this time the address info is taken from file filename. This can be used if
ARP entries for a lot of hosts have to be set up. The name of the data file is very often /etc/ethers,
but this is not official. If no filename is specified /etc/ethers is used as default.
B.
/etc/ethers
