Exercise 5.4.1
If you needed to determine the computer name used for node E on the network (starting from node A), what command would you use to get this information? Give the command sequence you would enter at the command line to retrieve this information.
I already have the IP Addresses for all the workstations a simple Ping command in CMD will work. Windows+R will bring up run command type CMD or go to start menu then accessories CMD. From CMD we would type Ping –a 192.168.1.5 to retrieve the information we need.
Exercise 5.4.2
What is the best (easiest and most efficient) command to determine whether all the hosts on the local-area network are reachable? You can assume that you are starting from computer A. List the command sequence(s) you would need to enter to test this functionality.
Windows+R will bring up run command type CMD or go to start menu then accessories CMD. From CMD we would type Ping 192.168.1.5, Ping 192.168.1.4, and Ping 192.168.1.3, Ping 192.168.1.6, and Ping 192.168.1.2. This would be a quick easier way but for a more complex way type FOR /L %i IN (1,1,254) DO ping -n 1 192.168.1.%i | FIND /i "Reply">>c:\ipaddresses.txt in CMD. exercise 5.4.3
