This LPIC-2 practice question tests your understanding of linux kernel and system startup. 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 directories or files are typically associated with the Linux kernel? (Choose three.)
/proc
/proc is a virtual filesystem that provides kernel and process information.
/dev
Why wrong: /dev contains device files, largely managed by udev, not directly the kernel.
/etc
Why wrong: /etc contains system configuration files, not kernel-specific.
/sys
/sys is a virtual filesystem that exposes kernel objects.
/boot/vmlinuz-*
The vmlinuz-* files are the compressed kernel images.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
/proc
/proc is a virtual filesystem that provides an interface to kernel data structures, exposing process information, system hardware details, and runtime kernel parameters. It is dynamically generated by the kernel and does not occupy disk space, making it a direct representation of kernel state.
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.
/proc
Why this is correct
/proc is a virtual filesystem that provides kernel and process information.

/dev

/etc
Why it's wrong here
/etc contains system configuration files, not kernel-specific.
/sys
Why this is correct
/sys is a virtual filesystem that exposes kernel objects.

/boot/vmlinuz-*
Why this is correct

Common exam traps
The trap here is that candidates often confuse /dev as a kernel-associated directory because it contains device nodes, but /dev is a user-space interface managed by udev, whereas /proc and /sys are virtual filesystems directly maintained by the kernel.
Detailed technical explanation
The /proc filesystem (procfs) exposes kernel parameters like /proc/sys for sysctl tuning, while /sys (sysfs) provides a structured view of kernel objects, devices, and drivers. /boot/vmlinuz-* is the compressed kernel image loaded by the bootloader (e.g., GRUB) into memory during startup; its filename typically includes the kernel version and is used with initramfs to mount the root filesystem.
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-2 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.
