SIMULATION - You are working as an Administrator. There is a common data shared (/data) from 192.168.0.254 to all users in your local LAN. When user`s system start, shared data should automatically mount on /common directory. 

Please see explanation

To automatically mount at boot time, we use the /etc/fstab file. Because /etc/rc.d/rc.sysinit file reads and mounts all file system specified in /etc/fstab. To mount Network Sharing Files also use the /etc/fstab but filesystem is nfs.
