Exercise 1

Start by using ping to check connectivity with CrucialExams.com

ping Crucialexams.com

Exercise 2

Definitely some connectivity issues there, let's check our IP configuration

ipconfig

Exercise 3

The configuration looks fine, try to ping the default gateway to check for local connectivity.

ping 192.168.1.1

Exercise 4

Doesn't look like we have local connectivity either, try getting a new IP Address using DHCP. Start by clearing the current configuration.

ipconfig /release

Exercise 5

Now that we have released our IP Configuration, use a command to get a new one via DHCP

ipconfig /renew

Exercise 6

Notice our default gateway, subnet mask, and IP address have all changed. Try to ping the new default gateway to check for connectivity.

ping 172.25.0.1

Exercise 7

Great! Internal connectivity seems to be working, try contacting the Crucial Exams servers to verify internet connectivity.

ping Crucialexams.com

Woo-hoo, you're done! You successfully completed all the command line exercises.

What you did: Verified the issue, found the root cause, implemented a solution, verified the solution.
