A company has client computers that run Windows 7 Enterprise, a single subnet, and servers that
run Windows Server 2008 R2. A client computer can connect to the company’s servers by using IP
addresses, but not by using fully qualified domain names (FQDNs). You need to ensure that the client
computer can resolve to the company* s servers by using FQDNs. Which addresses should you
change? To answer, select the appropriate addresses in the work area.
Answer:

Yes. I concur, DNS.
