Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
LVM: Allows flexible disk management with volume groups and logical volumes
The correct matches are: LVM for flexible disk management with VGs and LVs, RAID for combining disks for redundancy/performance, Stratis for pool-based snapshots and thin provisioning, and VDO for block-level deduplication/compression. Common confusions include swapping LVM with VDO and RAID with Stratis.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
LVM: Allows flexible disk management with volume groups and logical volumes
Why this is correct
LVM (Logical Volume Manager) provides a flexible approach to disk management by abstracting physical storage into volume groups and logical volumes.
LVM: Deduplicates and compresses data at the block level
Why it's wrong here
This describes VDO (Virtual Data Optimizer), not LVM. LVM does not perform deduplication or compression.
RAID: Combines multiple disks for redundancy or performance
Why this is correct
RAID (Redundant Array of Independent Disks) uses multiple disks to provide data redundancy (e.g., RAID 1, 5, 6) or performance improvement (e.g., RAID 0).
RAID: Provides thin provisioning and snapshots using a pool-based model
Why it's wrong here
This describes Stratis, not RAID. Stratis uses a pool-based model for thin provisioning and snapshots.
Stratis: Provides advanced storage features like snapshots and thin provisioning using a pool-based model
Why this is correct
Stratis is a storage management solution that simplifies the management of filesystems with features like thin provisioning, snapshots, and pooling.
VDO: Deduplicates and compresses data at the block level
Why this is correct
VDO (Virtual Data Optimizer) reduces storage usage by performing block-level deduplication and compression.
Quick reference
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
