- A
Custom roles are available for all Google Cloud services by default.
Why wrong: Custom roles are not available for all services by default; they must be enabled and are limited to certain services.
- B
IAM roles are collections of permissions.
Correct. IAM roles are indeed collections of permissions.
- C
Roles assigned to a project are automatically inherited by all resources in the project.
Correct. Project-level IAM roles are inherited by all resources in the project unless overridden.
- D
The basic roles include Owner, Editor, and Viewer.
Correct. The primitive/basic roles are Owner, Editor, and Viewer.
- E
Primitive roles are the same as predefined roles.
Why wrong: False. Primitive roles and predefined roles are different; predefined roles are more specific and fine-grained.
Google ACE Practice Question: Which TWO statements are true about Cloud IAM…
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 statements are true about Cloud IAM roles?
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
IAM roles are collections of permissions.
Options B, C, and D are all true statements about Cloud IAM. Option B correctly defines IAM roles as collections of permissions that grant specific access. Option C is true because IAM policies are hierarchical; roles assigned at the project level are inherited by all resources within that project by default. Option D is accurate as the basic roles in Google Cloud IAM are Owner, Editor, and Viewer. Options A and E are false: custom roles are not available for all services by default (they require enabling the relevant API), and primitive roles (the old term) are not the same as predefined roles; predefined roles are more granular and service-specific.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
One common misconception is that custom roles are available for all services, but they have limitations. Also, while project-level roles are inherited, some resources (e.g., Cloud Storage buckets) can have their own IAM policies that override inheritance, but the default behavior is inheritance.
Detailed technical explanation
How to think about this question
Under the hood, IAM roles are defined by a list of permissions in the form of `service.resource.verb` (e.g., `compute.instances.start`). When a role is assigned at the project level, it applies to all resources in that project only if those resources do not have a more specific IAM policy binding; however, resources like Compute Engine instances can have their own IAM policies via the `setIamPolicy` method, which can override project-level bindings. In practice, a common scenario is granting a user the `roles/compute.instanceAdmin` role at the project level, but then restricting access to specific instances by setting a separate IAM policy on those instances, demonstrating that inheritance is not automatic and can be overridden.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
