LPIC-1 Devices, Filesystems and FHS Practice Question
This LPIC-1 practice question tests your understanding of devices, filesystems and fhs. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
/dev/sda3
The /etc/fstab file defines the order in which filesystems are checked by fsck during boot, based on the sixth field (pass number). A pass number of 1 is checked first (typically the root filesystem), 2 is checked next (other filesystems), and 0 means no check. In the exhibit, /dev/sda3 has a pass number of 2, but since it is listed last among the entries with pass number 2, it will be checked after all other pass-2 filesystems, making it the last one checked overall.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
/dev/sda3
Why this is correct
Pass 2, checked after pass 1 filesystems and before any higher pass numbers.

✗
/dev/sda2
Why it's wrong here
Pass 1, checked before pass 2.
✗
/dev/sda1
Why it's wrong here
Pass 1, checked before pass 2.
✗
/dev/sdb1
Why it's wrong here
Pass 0, not checked.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume the pass number alone determines the order, ignoring that filesystems with the same pass number are checked sequentially based on their listing order in /etc/fstab.
Detailed technical explanation
How to think about this question
The fsck order is determined by the pass number in /etc/fstab, but within the same pass number, the order follows the sequence of entries in the file (top-to-bottom). The root filesystem is typically assigned pass 1 to ensure it is checked first, while other filesystems use pass 2 and are checked in the order they appear. A pass of 0 disables checking entirely, which is common for swap or pseudo-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 LPIC-1 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.
