where is dhclient.conf? I need to create it? If yes, where're the default options?
The dhclient.conf file doesn't exist by default in more modern versions of CentOS. You'll need to create it in /etc/dhcp, or by putting the requested options in /etc/dhcp/dhclient.d
For CentOS 7, it should be safe to use http://pkgs.fedoraproject.org/cgit/dhcp.git/plain/README.dhclient.d as guidelines should you choose the latter route.
