Question 8

Which of the following lines stems from an ARP table?

A.? (192.168.122.1) at 52:54:00: a3:4e: 0e on em0
B.inet 192.168.122.11 netmask 0xffffff00 broadcast 192.168.122.255
C.127.0.0.1 localhost localhost.my.domain
D.tcp4 0 0 192.168.122.11.22 192.168.122.1.38058 ESTABLISHED
E.localhost link#2 UH lo0

Correct Answer: A

Explanation
This line stems from an ARP table because it shows the association between an IP address (192.168.122.1) and a MAC address (52:54:00: a3:4e: 0e) on a network interface (em0). ARP stands for Address Resolution Protocol, which is used to map IP addresses to MAC addresses on a local network. An ARP table is a list of these mappings that is maintained by each host on the network. The other lines are not from an ARP table, but from different sources, such as:
B: inet 192.168.122.11 netmask 0xffffff00 broadcast 192.168.122.255: This line is from the output of the ifconfig command, which displays the configuration of network interfaces. It shows the IP address, netmask, and broadcast address of the interface.
C: 127.0.0.1 localhost localhost.my.domain: This line is from the /etc/hosts file, which is used to map hostnames to IP addresses. It shows that the loopback address (127.0.0.1) is associated with the hostname localhost and the fully qualified domain name localhost.my.domain.
D: tcp4 0 0 192.168.122.11.22 192.168.122.1.38058 ESTABLISHED: This line is from the output of the netstat command, which displays the status of network connections. It shows that there is an established TCP connection between the local host (192.168.122.11) on port 22 and the remote host (192.168.122.1) on port 38058.
E: localhost link#2 UH lo0: This line is from the output of the route command, which displays the routing table. It shows that the destination localhost is reachable via the link layer interface lo0, which is the loopback interface. The UH flags indicate that the route is up and uses a host-specific gateway.
