mount CD on RHEL 7 Linux

run blkid to find out the correct device, example /dev/sr0

Create a mount point if it doesn't already exist.

mount /dev/sr0 /mnt/cdrom

mount /dev/cdrom /mnt/cdrom (might work)

RHEL Network configuration

The primary network configuration files are as follows:

/etc/hosts

Resolve host names that cannot be resolved any other way, by DNA for example. 

/etc/resolv.conf

This file specifies the IP addresses of DNS servers and the search domain.

/etc/sysconfig/network

This file specifies routing and host information for all network interfaces.

/etc/sysconfig/network-scripts/ifcfg-interface-name

For each network interface, there is a corresponding interface configuration script. Each of these files provide information specific to a particular network interface.
