The answer is IOPS requirements for the database workload and encryption at rest support. IOPS, or input/output operations per second, directly determines how quickly the database can read and write data, which is critical for a 500 GB database growing 10% monthly—insufficient IOPS will cause performance bottlenecks as the workload scales. Encryption at rest ensures data stored on disk is protected, often through transparent data encryption or server-side encryption with customer-managed keys, and the chosen storage type must support these features to meet compliance mandates. On the CompTIA Cloud+ CV0-004 exam, this question tests your ability to balance performance and security when selecting storage for a managed database; a common trap is focusing only on capacity growth while ignoring the workload’s read/write demands. Remember the mnemonic “I-O-E” for IOPS and Encryption—two pillars that govern both speed and safety in cloud storage decisions.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
IOPS (Input/Output Operations Per Second) directly impacts database query performance, especially for transactional workloads; selecting a storage type with insufficient IOPS can lead to throttling and latency spikes. For a 500 GB database growing 10% monthly, provisioning storage with adequate IOPS and throughput (e.g., AWS gp3 or io2 volumes) is essential to handle peak loads without re-provisioning. Encryption at rest often requires specific storage features like hardware security module (HSM) integration or key management service (KMS) support, which may not be available on all storage tiers.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.

Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
