The correct answer is to implement a VPN tunnel between the cloud VPC and the on-premises network. This solution encrypts all IP traffic at the network layer, creating a secure, encrypted tunnel that protects data in transit across the public internet between your cloud and on-premises environments. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding of network security controls for hybrid cloud connectivity, often appearing as a direct comparison against less comprehensive options like SSL/TLS for individual applications or IPsec without a full tunnel. A common trap is confusing application-layer encryption (e.g., HTTPS) with network-layer encryption—remember that a VPN tunnel covers all traffic, not just specific ports. Memory tip: “Tunnel all traffic, not just one app” to distinguish a VPN from a simple encrypted connection.
CV0-004 Operations and Support Practice Question
This CV0-004 practice question tests your understanding of operations and support. 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.
A company is migrating its on-premises workloads to a public cloud. The security team requires that all data in transit between the cloud resources and on-premises be encrypted. Which solution should the cloud architect recommend?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement a VPN tunnel between the cloud VPC and the on-premises network.
A VPN tunnel encrypts all IP traffic between the cloud VPC and on-premises network, covering all data in transit. Other options are insufficient or address different aspects.
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.
✗
Deploy a hardware security module (HSM) for key management.
Why it's wrong here
HSM manages encryption keys but does not encrypt data in transit.
✗
Enable encryption on the cloud storage buckets.
Why it's wrong here
Storage encryption protects data at rest, not in transit.
✗
Use TLS for all application traffic.
Why it's wrong here
TLS only encrypts application-layer traffic; other protocols may be unencrypted.
✓
Implement a VPN tunnel between the cloud VPC and the on-premises network.
Why this is correct
Correct. A VPN encrypts all network traffic between sites, ensuring all data in transit is encrypted.

Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
