A system administrator needs to ensure that a Linux server can boot properly even if a non-essential network share, defined in /etc/fstab, is unavailable. Which mount option should be added to the relevant entry in /etc/fstab to achieve this?
defaults
noauto
nofail
nodev
The correct answer is nofail. The nofail option in /etc/fstab instructs the system to not report an error and to continue the boot process if the specified device is not present or cannot be mounted. This is essential for non-critical filesystems, such as network shares, that might be temporarily unavailable during a reboot.
noauto is incorrect because it prevents the filesystem from being mounted automatically at boot time. The administrator wants the share to mount if it's available, but not to halt the boot process if it is not. noauto would require a manual mount every time.nodev is a security option that prevents the interpretation of character or block special devices on the filesystem. It has no effect on whether the system boots if the device is unavailable.defaults is a placeholder for a standard set of options, typically including auto, rw, suid, dev, exec, nouser, and async. It does not include the nofail option, so using defaults alone would still cause the system to wait and potentially fail to boot if the network share is unreachable.Bash is our AI bot, trained to help you pass your exam.
