While troubleshooting a workstation connectivity problem, you enter the following command: ping 127.0.0.1. The response indicates the test failed. What can you determine about that workstation?a. Its network cable is faulty or not connected to the wall jack.b. Its TCP/IP stack is not installed properly.c. It has been prevented from transmitting data past the default gateway.d. Its DHCP settings are incorrect.e. Its DNS name server specification is incorrect.
Linux Command
Function
ifconfig also: ifcfg, ifup, ifdown, ethtool, nm-tool
/etc/init.d/networking restart ip link set down ip link set up
The ifconfig command is a tool used to display and configure network interfaces. This command will display information about the network card, IP address, broadcast address, and network mask. It also shows how many packets were received and transmitted. There is also information about the loopback device (lo).
ping
The ping command allows the user to test whether or not a network connection is active, the speed of that connection, and how a network behaves given specific data loads.
arpalso: arping
The arp command by itself is used to view the information currently in the ARP table (Address Resolution Protocol). This table maps the IP address of machines on your network segment with their MAC address.

The hostname command tells you what the hostname of your machine is set to. The…
Computer Science
Arriving at your university room, you plug into the wired Ethernet jack for the first time. The network admin has a record of your MAC address and your machine can join the network without further action on your part. Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCP.
