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.
Which of the following directories is NOT defined in the Filesystem Hierarchy Standard (FHS)?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "NOT"
Why it matters: Negative qualifier — you are looking for the one option that does NOT apply. Most options will be true; only one is false for this scenario.
/run
Why wrong: /run is a standard temporary filesystem for runtime data.
/proc
Why wrong: /proc is a standard virtual filesystem.
/net
/net is not defined in the FHS.
/media
Why wrong: /media is standard for removable media mount points.
/sys
Why wrong: /sys is standard for kernel and device information.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
/net
The /net directory is not defined in the Filesystem Hierarchy Standard (FHS). The FHS specifies standard directory locations like /run, /proc, /media, and /sys, but /net is not a required or standard directory; it may appear in some systems as a mount point for network filesystems but is not part of the FHS specification.
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.
/run
Why it's wrong here
/run is a standard temporary filesystem for runtime data.
/proc
Why it's wrong here
/proc is a standard virtual filesystem.
/net
Why this is correct
/net is not defined in the FHS.
Clue confirmation
The clue word "NOT" in the question point toward this answer.

/media
Why it's wrong here
/media is standard for removable media mount points.
/sys
Why it's wrong here
/sys is standard for kernel and device information.
Common exam traps
The trap here is that candidates may assume /net is a standard FHS directory because it appears in some distributions for network mounts, but the FHS does not define it, and the exam expects knowledge of the official standard directories.
Detailed technical explanation
The FHS (Filesystem Hierarchy Standard) is maintained by the Linux Foundation and defines the directory structure for Unix-like systems. /run was introduced in FHS 3.0 to replace /var/run and /var/lock, providing a tmpfs-based location for runtime data that is cleared on reboot. /proc and /sys are virtual filesystems that expose kernel data structures and device information, while /media is used by automounting utilities like udisks. The /net directory is not part of FHS and is often used locally for NFS mounts or network shares, but its existence is distribution-specific.
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 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.
