You work as a Network Administrator for NetTech Inc. When you enter http://66.111.64.227 in the
browser’s address bar, you are able to access the site. But, you are unable to access the site when
you enter http://www.company.com. What is the most likely cause?
A.
The site’s Web server is offline.
B.
The site’s Web server has heavy traffic.
C.
WINS server has no NetBIOS name entry for the server.
D.
DNS entry is not available for the host name.
Explanation:
You are unable to access the site on entering http://www.company.com because the
DNS server has no entry for the host name
www.company.com. DNS server resolves host name to IP address. If the DNS entry is not found, the
browser’s request by host name cannot
be resolved. Hence, you will access the site only by specifying the IP address of the site.
