LPIC-1 System Architecture Practice Question
A server has two disk drives: /dev/sda (SSD) and /dev/sdb (HDD). The administrator wants to place frequently accessed files on the SSD for performance. Which approach best achieves this using Linux filesystem features?
⚠ Common exam trap
Candidates often confuse RAID 0's speed benefits with the goal of isolating hot data, failing to recognize that RAID 0 mixes all data across both disks, preventing the administrator from selectively placing frequently accessed files on the faster SSD.
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
✓
Create separate LVM logical volumes on each disk and mount them at different mount points.
LVM allows the administrator to create separate logical volumes on each physical disk (/dev/sda and /dev/sdb) and mount them at distinct mount points. By placing frequently accessed files on the SSD logical volume and less critical data on the HDD logical volume, the administrator can directly control which files benefit from the SSD's faster performance without mixing data or requiring complex overlays.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create separate LVM logical volumes on each disk and mount them at different mount points.
Why this is correct
LVM allows flexible allocation of storage from different physical volumes.
- ✗
Configure RAID 0 across both disks to combine speed.
Why it's wrong here
RAID 0 stripes data, so both disks are used equally; slow disk becomes bottleneck.
- ✗
Use symbolic links to redirect file access to the SSD.
Why it's wrong here
Symlinks are manual and not suitable for dynamic file placement.
- ✗
Use a union mount to overlay the SSD on top of the HDD.
Why it's wrong here
Union mounts are not typically used for this purpose and add complexity.
