- A
e2label /dev/sdc1 data
Why wrong: Setting a label is optional.
- B
mkfs.ext4 /dev/sdc1
Creates the ext4 filesystem.
- C
mkdir /mnt/data
Creates the mount point directory.
- D
mount /dev/sdc1 /mnt/data
Why wrong: Manual mount is not needed for auto-mount at boot.
- E
add entry to /etc/fstab for /dev/sdc1
fstab entry ensures mount at boot.
Question 511 of 513
LFCS Storage Management Practice Question
This LFCS practice question tests your understanding of storage management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE steps are required to create a new ext4 filesystem on /dev/sdc1 and ensure it is automatically mounted at /mnt/data at boot? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
mkfs.ext4 /dev/sdc1
B is correct because `mkfs.ext4 /dev/sdc1` creates a new ext4 filesystem on the specified partition. This is the fundamental step to format the device with the ext4 filesystem type, which is required before the partition can be mounted and used for data storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the temporary `mount` command (which does not persist across reboots) with the permanent configuration required in /etc/fstab, and may also mistakenly think setting a filesystem label is a required step for creating or mounting a filesystem.
Detailed technical explanation
How to think about this question
The `mkfs.ext4` command writes the ext4 superblock, inode table, and journal to the partition, initializing the filesystem structure. For automatic mounting at boot, the /etc/fstab entry must include the device or UUID, mount point, filesystem type, and mount options (e.g., defaults 0 2), and the mount point directory must exist before the mount is attempted. The `mount -a` command, run at boot by systemd or init scripts, reads /etc/fstab to mount all listed filesystems.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the LFCS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
