CV0-004 Practice Question: A DevOps team uses infrastructure as code to…
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 choices
Why each option matters
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.
Using a cloud policy service (e.g., AWS Service Control Policy, Azure Policy, or GCP Organization Policy) can enforce rules like 'deny public access' and 'require versioning' at the account or organizational level, automatically applying to all storage resources. Option A is wrong because pre-commit hooks check templates but do not enforce at deployment; they can be bypassed. Option B is wrong because security groups apply to network resources like VMs, not storage buckets. Option D is wrong because a manual approval gate adds human review but does not automatically enforce the security 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.
- ✗
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.
- ✗
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.
