LPIC-2 Linux Kernel and System Startup Practice Question
Exhibit
BOOT_IMAGE=/boot/vmlinuz-5.10.0-8-amd64 root=/dev/sda1 ro quiet splash
Refer to the exhibit. Which kernel parameter is responsible for reducing the amount of kernel messages displayed on the console?
⚠ Common exam trap
Test-takers frequently confuse `quiet` with `splash`, thinking both suppress messages, but `splash` only hides them visually while the kernel still generates the same output, whereas `quiet` actually reduces the kernel's console log level.
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
✓
quiet
The `quiet` kernel parameter suppresses most kernel log messages from being printed to the console during boot, reducing console output to only critical or error-level messages. This is controlled by the kernel's console log level, which `quiet` effectively lowers to KERN_WARNING (4) or higher, filtering out informational and debug messages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ro
Why it's wrong here
'ro' mounts the root filesystem read-only; does not affect message output.
- ✗
splash
Why it's wrong here
'splash' is for a graphical boot splash, not message reduction.
- ✓
quiet
Why this is correct
The 'quiet' parameter suppresses most kernel messages on the console.
- ✗
BOOT_IMAGE
Why it's wrong here
BOOT_IMAGE is set by GRUB to indicate the kernel image; does not affect messages.
