CV0-004 Cloud Architecture and Design Practice Question
This CV0-004 practice question tests your understanding of cloud architecture and design. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
An organization must comply with a regulation requiring that all data stored in the cloud be encrypted at rest using a cloud provider's native encryption service. The company also needs to maintain control over the encryption keys. Which solution should the architect recommend?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the cloud provider's native encryption service with customer-managed keys
Option A is correct because the regulation requires cloud-native encryption at rest with customer-controlled keys. Cloud providers offer services like AWS KMS with customer-managed keys (CMKs) or Azure Key Vault with customer-managed keys, which allow the organization to create, rotate, and disable keys independently while the provider handles the underlying encryption of data at rest using envelope encryption. This satisfies both the 'native encryption service' and 'maintain control over the encryption keys' 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.
✓
Use the cloud provider's native encryption service with customer-managed keys
Why this is correct
This meets compliance and provides key control through the provider's key management service.
Related concept
Read the scenario before looking for a memorised answer.
✗
Encrypt the data on-premises before uploading to the cloud
Why it's wrong here
This requires additional steps and may not leverage native cloud encryption.
✗
Use the cloud provider's default encryption with provider-managed keys
Why it's wrong here
Provider-managed keys do not give the organization control over the keys.
✗
Use a third-party hardware security module (HSM) hosted on-premises
Why it's wrong here
This is not a native cloud solution and may not integrate seamlessly.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between 'native encryption service' and 'encryption at rest'—candidates mistakenly think any encryption (like client-side or third-party HSM) satisfies the requirement, but the question explicitly demands the cloud provider's native service with customer-managed keys.
Detailed technical explanation
How to think about this question
Under the hood, cloud-native encryption services like AWS KMS use envelope encryption where a customer-managed key (CMK) encrypts data keys, which then encrypt the actual data. The CMK never leaves the HSM-backed key store, and the customer can enable key rotation, disable keys, or set key policies via IAM. In a real-world scenario, if the organization needs to revoke access to data immediately, they can disable the CMK, rendering all data encrypted under that key inaccessible—something not possible with provider-managed keys.

→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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
