DS0-001 Database Planning And Deployment Practice Question
Which TWO database deployment configurations help mitigate the impact of a hardware failure on the primary storage controller?
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
✓
Multi-path I/O (MPIO) configuration
Redundancy at the hardware/storage layer is achieved through RAID configurations and multi-path I/O (MPIO).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Full recovery model enabled
Why it's wrong here
This is a log management setting, not a hardware redundancy feature.
- ✓
Multi-path I/O (MPIO) configuration
Why this is correct
MPIO provides redundant paths between the server and storage, protecting against controller failure.
- ✓
RAID 10 configuration for data volumes
Why this is correct
RAID 10 provides redundancy and performance in case of disk failure.
- ✗
SQL Server Always On
Why it's wrong here
This provides database-level failover, but not physical storage controller redundancy.
- ✗
Database partitioning
Why it's wrong here
Partitioning is for performance and manageability, not hardware fault tolerance.
Quick reference
RAID Level Comparison
| 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.
