EX200 Configure local storage Practice Question
An administrator needs to ensure that a specific LVM logical volume is automatically mounted at boot with the 'noexec' option. Which configuration file and entry should be used?
⚠ Common exam trap
Many candidates confuse the purpose of /etc/fstab with boot scripts like rc.local, or they forget that mount options in fstab must be comma-separated and include 'defaults' to ensure all standard options are explicitly set before overriding them.

Correct answer & explanation
✓
/etc/fstab: /dev/vg/lv /mnt ext4 defaults,noexec 0 0
/etc/fstab is the standard configuration file for defining filesystem mount points and options that are applied automatically at boot. The entry specifies the logical volume device, mount point, filesystem type, and mount options including 'noexec' to prevent execution of binaries on that filesystem. The 'defaults' keyword ensures standard mount behavior is applied before the 'noexec' option overrides the exec permission.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
/etc/fstab: /dev/vg/lv /mnt ext4 noexec 0 0
Why it's wrong here
Missing 'defaults' before noexec; 'noexec' alone is acceptable but typically combined with defaults.
- ✗
/etc/rc.d/rc.local: mount /dev/vg/lv /mnt -o noexec
Why it's wrong here
Not the standard method; fstab is used for automatic boot mounts.
- ✓
/etc/fstab: /dev/vg/lv /mnt ext4 defaults,noexec 0 0
Why this is correct
Correct fstab entry.
- ✗
/etc/rc.local: mount -o noexec /dev/vg/lv /mnt
Why it's wrong here
rc.local is not the standard way; fstab is preferred for boot-time mounts.
