and what is this Domain of "workstation01.com" this answer is just ridiculous... I have been searching a lot on the internet. Nobody ever digs on their own machine name. It's just WEIRD. Can anyone explain why the answer is workstation01.com?

Since the SysAdmin can ping the DNS server... now the sysadmin executes the command line to perform a DNS lookup to see if the reply from the domain name server is valid. The nslookup can use an ip address or computer name. The computer name should be registered.

Correct answer A. If you can reach google (outside the local network, beyond the gateway) then the DNS server is working ok.
