CV0-004 Practice Question: Migrating its on-premises database to a…
A company is migrating its on-premises database to a cloud-based managed database service. The database is currently 500 GB and is expected to grow by 10% monthly. Which TWO factors should the company consider when selecting the storage type?
⚠ Common exam trap
CompTIA often tests the distinction between operational policies (like backup frequency) and infrastructure decisions (like storage type), leading candidates to mistakenly select backup-related options when the question explicitly asks about storage type selection.

Correct answer & explanation
✓
Encryption at rest requirements.
Encryption at rest is a critical consideration when selecting storage for a cloud-based managed database service, as it ensures data is encrypted when stored on disk. Many cloud providers offer transparent data encryption (TDE) or server-side encryption with customer-managed keys (CMKs), and the storage type must support these features to meet compliance requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Backup frequency and retention.
Why it's wrong here
Backup settings are independent of storage type.
- ✗
Physical location of the data center.
Why it's wrong here
Location is a region/zone decision, not storage type.
- ✓
Encryption at rest requirements.
Why this is correct
Some storage types may not support encryption or may have additional cost.
- ✗
Operating system compatibility with the storage.
Why it's wrong here
Managed database abstracts the OS.
- ✓
IOPS requirements for the database workload.
Why this is correct
Different storage types offer different IOPS performance.
