FC0-U71 Practice Question: A technician is selecting a storage solution for…
A technician is selecting a storage solution for a home server that requires fast access speeds and redundancy against a single drive failure. Which TWO technologies should be considered?
⚠ Common exam trap
Candidates often confuse RAID 0 with RAID 1, mistakenly thinking RAID 0 provides redundancy because it improves performance, or they overlook that SSDs are necessary for fast access speeds, assuming HDDs are sufficient for a home server.
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
✓
SSD
SSD (Solid State Drive) provides fast access speeds due to its use of NAND flash memory, which eliminates mechanical seek times and rotational latency found in HDDs. This makes it ideal for a home server requiring rapid data retrieval. RAID 1 (mirroring) writes identical data to two drives, offering redundancy against a single drive failure by allowing the system to continue operating if one drive fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SSD
Why this is correct
SSDs offer fast read/write speeds compared to HDDs.
- ✗
Cloud storage
Why it's wrong here
Cloud storage depends on internet speed and may not provide fast local access.
- ✗
HDD
Why it's wrong here
HDDs are slower than SSDs, not ideal for fast access.
- ✓
RAID 1
Why this is correct
RAID 1 provides mirroring for redundancy, protecting against a single drive failure.
- ✗
RAID 0
Why it's wrong here
RAID 0 improves speed but has no redundancy.
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.
