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
✓
Organization policy with a list constraint.
Organization policies can enforce constraints like constraints/storage.uniformBucketLevelAccess to require uniform bucket-level access. Option B (IAM roles with custom permissions) cannot deny bucket creation with specific settings. Option C (Cloud Audit Logs) is for logging, not enforcement. Option D (Cloud Armor) is for security policies at the edge.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Organization policy with a list constraint.
Why this is correct
An organisation policy with a list constraint enforces exactly this prohibition: the constraint `storage.uniformBucketLevelAccess` accepts allowed values, and denying `false` blocks bucket creation where uniform bucket-level access is disabled. This satisfies the stem's requirement to prevent, rather than merely detect, non-compliant buckets across the organisation.
- ✗
IAM roles with custom permissions to deny bucket creation.
Why it's wrong here
IAM controls who can create buckets, not how they are configured.
- ✗
Cloud Audit Logs to monitor bucket creation.
Why it's wrong here
Logging is reactive, not preventive.
- ✗
Cloud Armor security policies.
Why it's wrong here
Cloud Armor protects against DDoS, not resource configurations.
