You have a file /etc/resolv.conf, but the computer does not use the configured DNS servers to look up host names.
What is most likely the problem?
A. The hosts entry in your /etc/nsswitch.conf does not list dns.
B. You do not have a /etc/named.conf file.
C. The localhost hostname is not properly configured in /etc/hosts.
D. The named daemon is not running on your computer.
