This ACE practice question tests your understanding of setting up a cloud solution environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which two actions are required to allow a user to create a Cloud Storage bucket using gcloud?
Set up billing
Why wrong: Billing is already typically set up when the project is created.
Create a service account
Why wrong: Service account is not required; user can use their own account.
Assign the user roles/storage.admin
Storage admin includes bucket create permission.
Enable the Cloud Storage API
APIs must be enabled for the project.
Assign the user roles/storage.objectAdmin
Why wrong: Object admin does not include bucket create.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Assign the user roles/storage.admin
Option C is correct because the `roles/storage.admin` IAM role includes the `storage.buckets.create` permission, which is required to create a Cloud Storage bucket using the gcloud command. Without this role, the user will receive a permission denied error even if other prerequisites like billing are configured.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Google Cloud often tests the distinction between bucket-level permissions (e.g., `storage.buckets.create`) and object-level permissions (e.g., `storage.objects.create`), leading candidates to mistakenly choose `roles/storage.objectAdmin` because it sounds like it covers all storage administration.
Detailed technical explanation
The `gcloud storage buckets create` command authenticates the user via OAuth 2.0 and checks IAM permissions at the project level. The `roles/storage.admin` role is a predefined role that includes all storage.buckets.* permissions, while `roles/storage.objectAdmin` is scoped only to object-level operations. In a real-world scenario, a DevOps engineer might be assigned `roles/storage.admin` to manage bucket lifecycle, while a data analyst only needs `roles/storage.objectAdmin` to upload files to existing buckets.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
