20+ practice questions focused on Trust and security with Google Cloud — one of the most tested topics on the Google Cloud Digital Leader exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Trust and security with Google Cloud PracticeA security audit finds that a company's application service accounts have been granted broad IAM roles (e.g., Storage Admin on the entire project) when they only need to read specific Cloud Storage buckets. The auditor recommends following the principle of least privilege. What is the most precise way to implement this for the Cloud Storage use case?
Explanation: It grants the minimal required permission (Storage Object Viewer) at the specific bucket level, adhering to the principle of least privilege. This ensures the service account can only read objects in that bucket and cannot perform any other storage operations, even accidentally. Granting roles at the resource level (bucket) rather than the project level eliminates unnecessary broad access.
A small IT team needs to grant developers the ability to deploy instances in a project but not delete them. Which IAM best practice should they use?
Explanation: It follows the IAM best practice of using organizational policies to enforce constraints on resources. By applying an organization policy that restricts the deletion of compute instances, the IT team can allow developers to have IAM permissions to deploy instances (e.g., compute.instances.insert) but prevent them from deleting them, without granting delete permissions directly. This approach aligns with least privilege by using policy-level controls to override allowed actions.
A financial services company needs to ensure that all access to sensitive data in Cloud Storage is logged with information about the user and the reason for access. Which feature should they enable?
Explanation: Access Transparency provides detailed logs of actions taken by Google Cloud support and engineering personnel when accessing customer data, including the specific user and the business reason for access. This meets the requirement for logging access with user identity and reason, as Cloud Audit Logs do not capture the business justification.
Refer to the exhibit. A developer receives this error when trying to create a Compute Engine instance. The developer is authenticated as a user with Project Editor role. What is the most likely cause?
Explanation: The error occurs because the developer lacks the iam.serviceAccountUser role on the service account they are attempting to attach to the instance. Even though Project Editor includes compute.instances.create, creating an instance with a service account requires the iam.serviceAccounts.actAs permission on that service account (provided by roles/iam.serviceAccountUser). Without this, the API call is denied.
A company wants to grant a data analyst read-only access to specific BigQuery datasets, but only if the request comes from within the corporate network. Which two Google Cloud tools should they combine to enforce this?
Explanation: IAM defines the read-only role (e.g., roles/bigquery.dataViewer) for the data analyst, while VPC Service Controls create a security perimeter that restricts access to the BigQuery API from only the corporate network IP range. Together, they ensure the request is both authorized by IAM and originates from within the allowed VPC perimeter, blocking any access from outside the corporate network even if the IAM role is granted.
