LPIC-1 System Architecture Practice Question
Which TWO of the following are valid methods to reduce boot time on a Linux system? (Select exactly 2.)
⚠ Common exam trap
A common mix-up: candidates confuse 'reducing boot time' with 'reducing kernel size' or 'removing features,' but the two most effective methods are eliminating unnecessary startup processes (services) and upgrading the storage hardware to reduce I/O wait, not tweaking filesystem types or kernel logging verbosity.
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
✓
Disable unnecessary systemd services.
Disabling unnecessary systemd services reduces the number of processes that must be started during boot, directly decreasing the time spent in the target phase of systemd's parallel service activation. Each disabled service eliminates its own dependency resolution, unit loading, and execution overhead, which is especially impactful on systems with many enabled services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Disable unnecessary systemd services.
Why this is correct
Reduces the number of processes started sequentially.
- ✗
Use an initramfs with minimal drivers.
Why it's wrong here
initramfs is required; minimizing it helps but not as effective as other options.
- ✓
Replace a hard disk drive with a solid-state drive.
Why this is correct
SSDs have much faster read speeds, reducing boot times.
- ✗
Increase the kernel log level to debug.
Why it's wrong here
Debug logging adds overhead and increases boot time.
- ✗
Use ext2 instead of ext4 as the root filesystem.
Why it's wrong here
ext2 lacks journaling but not a significant boot time improvement.
