The correct answer is to implement a cloud policy that disallows public access and requires versioning on all storage resources. This works because cloud policy services, such as AWS Service Control Policies or Azure Policy, operate at the account or resource hierarchy level to automatically enforce storage security requirements, preventing any non-compliant deployment regardless of how the resource is created. On the CompTIA Cloud+ CV0-004 exam, this scenario tests your understanding of governance and automation within Infrastructure as Code environments, where the key trap is confusing manual reviews or CI/CD pipeline checks with account-wide policy enforcement—policies cannot be bypassed, while pipelines or manual steps can. A common memory tip is to think of cloud policies as a “permanent gatekeeper” that blocks misconfigurations at the source, not just during a specific build step.
CV0-004 Security Practice Question
This CV0-004 practice question tests your understanding of security. 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 DevOps team uses infrastructure as code to deploy cloud resources. Security policy requires that all storage buckets have versioning enabled and are not publicly accessible. How can these requirements be enforced automatically?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement a cloud policy that disallows public access and requires versioning on all storage resources.
Option D is correct because using a cloud policy service (e.g., AWS Service Control Policy or Azure Policy) can enforce rules like 'deny public access' and 'require versioning' at the account level. Option A is wrong because it relies on manual review. Option B is wrong because the CI/CD pipeline can be bypassed. Option C is wrong because security groups do not apply to storage.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Add pre-commit hooks to check the IAC templates for compliance.
Why it's wrong here
Hooks can be bypassed if developers commit directly.
✗
Use security group rules to restrict access to the storage buckets.
Why it's wrong here
Security groups control network traffic to instances, not storage buckets.
✓
Implement a cloud policy that disallows public access and requires versioning on all storage resources.
Why this is correct
Cloud policies provide preventive governance at the resource level.
Related concept
Standard ACLs match source addresses.
✗
Configure a manual approval gate in the deployment pipeline for any storage changes.
Why it's wrong here
Manual review is not automatic and can be missed.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related CV0-004 ACL questions on filtering logic and placement.
