CV0-004 Practice Question: A cloud administrator needs to design a storage…
A cloud administrator needs to design a storage solution that provides block-level access for a database server and must be highly durable. Which storage type should be used?
⚠ Common exam trap
CompTIA often tests the misconception that object storage can serve as a high-performance block store, but candidates must remember that object storage lacks the low-latency, block-level access and filesystem semantics required for transactional databases.
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
✓
Block storage
Block storage is the correct choice because it provides raw, low-latency block-level access that database servers require for high-performance read/write operations. It also supports features like RAID, snapshots, and replication to achieve high durability, making it ideal for transactional databases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
File storage
Why it's wrong here
File storage uses network file shares, not direct block access.
- ✓
Block storage
Why this is correct
Block storage provides raw volumes that databases can use and is durable.
- ✗
Archive storage
Why it's wrong here
Archive storage is for infrequently accessed data, not low-latency database needs.
- ✗
Object storage
Why it's wrong here
Object storage provides REST API access, not block-level.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is migrating a legacy application to the cloud. The application requires low-latency access to a shared filesystem that must be accessible from multiple virtual machines simultaneously. Which storage solution should the cloud architect recommend?
easy- A.Cold archive storage
- B.Local instance store
- ✓ C.Block storage
- D.Object storage
Why C: Block storage (C) is correct because it provides a shared filesystem that can be mounted by multiple virtual machines simultaneously with low-latency access. Services like Amazon EBS with multi-attach or Azure Managed Disks support concurrent read/write operations from multiple instances, meeting the legacy application's requirement for a shared, low-latency filesystem.
