LPIC-2 Linux Kernel and System Startup Practice Question
Which three directories or files are typically associated with the Linux kernel? (Choose three.)
⚠ Common exam trap
A common mix-up: candidates 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.
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
✓
/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.
Answer analysis
Option-by-option breakdown
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
Why it's wrong here
/dev contains device files, largely managed by udev, not directly the kernel.
- ✗
/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
The vmlinuz-* files are the compressed kernel images.
