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.)
e2label /dev/sdc1 data
Why wrong: Setting a label is optional.
mkfs.ext4 /dev/sdc1
Creates the ext4 filesystem.
mkdir /mnt/data
Creates the mount point directory.
mount /dev/sdc1 /mnt/data
Why wrong: Manual mount is not needed for auto-mount at boot.
add entry to /etc/fstab for /dev/sdc1
fstab entry ensures mount at boot.
Answer choices
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
Option A (mkfs.ext4) creates the filesystem. Option C (mkdir) creates the mount point. Option E (add to /etc/fstab) enables automatic mounting at boot. Option B (e2label) is optional. Option D (mount) is manual and not required for boot-time mounting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
e2label /dev/sdc1 data
Why it's wrong here
Setting a label is optional.
mkfs.ext4 /dev/sdc1

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
