- A
Set up billing
Why wrong: Setting up billing is a project-level prerequisite, but it is not an action the user needs to take to create a bucket. Billing is already configured for the project, so this is not a required action for the user.
- B
Create a service account
Why wrong: Creating a service account is not required; the user can be an individual user with appropriate IAM roles. Service accounts are used for applications, not for individual user access.
- C
Assign the user roles/storage.admin
Assigning the IAM role `roles/storage.admin` is required because it includes the `storage.buckets.create` permission needed to create a Cloud Storage bucket.
- D
Enable the Cloud Storage API
The Cloud Storage API must be enabled in the project before using gcloud to create buckets. If it is not enabled, the command will fail.
- E
Assign the user roles/storage.objectAdmin
Why wrong: The role `roles/storage.objectAdmin` provides object-level permissions but does not include `storage.buckets.create`, so it does not allow bucket creation.
Google ACE Practice Question: Which two actions are required to allow a user to…
This ACE practice question tests your understanding of ace exam topics. 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.
Which two actions are required to allow a user to create a Cloud Storage bucket using gcloud?
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
Assign the user roles/storage.admin
Options C and D are required. The user needs the `roles/storage.admin` IAM role (which includes the `storage.buckets.create` permission) to create a bucket via gcloud. Additionally, the Cloud Storage API must be enabled for the project; without it, gcloud commands will fail. Option A is incorrect because billing is a project-level prerequisite, not a direct action to allow a user. Option B is unnecessary; a user can use their own credentials. Option E is incorrect because `roles/storage.objectAdmin` only covers object-level permissions, not bucket creation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
The role `roles/storage.objectAdmin` provides object-level permissions but does not include `storage.buckets.create`, so it does not allow bucket creation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
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.
TExam Day Tips
- 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 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.
