Drive in `/etc/fstab`does not mount automatically after reboot

The possible culprit is that your network might not be available when the system is processing the fstab. I believe auto is the default but would encourage you to add it. Also add delay_connect to give time for the network to come fully up.

According to the mount manual the defaults options are rw, suid, dev, exec, auto, nouser, and async. So you can replace what you have and itemize the defaults while adding the delay_connect option.

123.234.123.234:/folder /home nfs rw,suid,dev,exec,auto,nouser,async,delay_connect  0 1

try the _netdev option

from the man page for mount:

The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system).
