LFCS Storage Management Practice Question
A system administrator needs to mount an ext4 filesystem with the options 'noatime' and 'errors=remount-ro'. Which mount command is correct?
⚠ Common exam trap
The trap here is that candidates may incorrectly use multiple `-o` flags (as in option B) or mistype the `errors` option (as in option A), confusing the `remount-ro` syntax with the unrelated `remount` command, or they may assume `atime=no` is a valid alternative to `noatime` (as in option C).

Correct answer & explanation
✓
mount -o noatime,errors=remount-ro /dev/sda1 /mnt
The `mount -o noatime,errors=remount-ro /dev/sda1 /mnt` command uses a single `-o` flag with a comma-separated list of mount options, which is the proper syntax for specifying multiple options. The `noatime` option disables updating the access time on reads, and `errors=remount-ro` tells the kernel to remount the filesystem as read-only if an I/O error is encountered, both of which are valid ext4 mount options.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
mount -o noatime,errors=remount /dev/sda1 /mnt
Why it's wrong here
The correct option is 'errors=remount-ro', not 'errors=remount'.
- ✗
mount -o noatime -o errors=remount-ro /dev/sda1 /mnt
Why it's wrong here
Multiple -o options are not the standard syntax; options should be comma-separated in one -o.
- ✗
mount -o atime=no,errors=remount-ro /dev/sda1 /mnt
Why it's wrong here
The option is 'noatime', not 'atime=no'.
- ✓
mount -o noatime,errors=remount-ro /dev/sda1 /mnt
Why this is correct
Comma-separated options in one -o is correct.
