Here are the GCP Exam questions along with their answers, correct answers, and explanations:
1. Question: You are designing cloud applications for a healthcare provider. The records management application will manage medical information for patients. Access to this data is limited to a small number of employees. The billing department application will have insurance and payment information. Another group of employees will have access billing information. In addition, the billing system will have two components: a private insurance billing system and a government payer billing system. Government regulations require that software used to bill the government must be isolated from other software systems. Which of the following resource hierarchies would meet these requirements and provide the most flexibility to adapt to changing requirements?
- Answer Choices:
- A. One organization, with folders for records management and billing. The billing folder would have private insurer and government payer folders within it. Common constraints would be specified in organization-level policies. Other policies would be defined at the appropriate folder.
- B. One folder for records management, one for billing, and no organization. Policies defined at the folder level.
- C. One organization, with folders for records management, private insurer, and government payer below the organization. All constraints would be specified in organization-level policies. All folders would have the same policy constraints.
- D. None of the above.
- Correct Answer: A
- Explanation: Option A provides a clear hierarchy with flexibility to define policies at different levels (organization, folder). This allows for isolation as required by regulations and adapts easily to changes in requirements.
2. Question: When you create a hierarchy, you can have more than one of which structure?
- Answer Choices:
- A. Organization only
- B. Folder only
- C. Folder and project
- D. Project only
- Correct Answer: C
- Explanation: In GCP, you can have multiple folders and projects within an organization, allowing you to organize resources in a flexible manner.
3. Question: You are designing an application that uses a series of services to transform data from its original form into a format suitable for use in a data warehouse. Your transformation application will write to the message queue as it processes each input file. You don’t want to give users permission to write to the message queue. You could allow the application to write to the message queue by using which of the following?
- Answer Choices:
- A. Billing account
- B. Service account
- C. Messaging account
- D. Folder
- Correct Answer: B
- Explanation: Service accounts can be used to grant specific permissions to applications without giving users those permissions.
4. Question: Your company has a number of policies that need to be enforced for all projects. You decide to apply policies to the resource hierarchy. Not long after you apply the policies, an engineer finds that an application that had worked prior to implementing policies is no longer working. The engineer would like you to create an exception for the application. How can you override a policy inherited from another entity in the resource hierarchy?
- Answer Choices:
- A. Inherited policies can be overridden by defining a policy at a folder or project level.
- B. Inherited policies cannot be overridden.
- C. Policies can be overridden by linking them to service accounts.
- D. Policies can be overridden by linking them to billing accounts.
- Correct Answer: A
- Explanation: Policies defined at a lower level in the hierarchy (folder or project) can override inherited policies.
5. Question: Constraints are used in resource hierarchy policies. Which of the following are types of constraints allowed?
- Answer Choices:
- A. Allow a specific set of values
- B. Deny a specific set of values
- C. Deny a value and all its child values
- D. Allow all allowed values
- E. All of the above
- Correct Answer: E
- Explanation: Constraints can be used to allow specific values, deny specific values, deny values and their children, and allow all allowed values.
6. Question: A team with four members needs you to set up a project that needs only general permissions for all resources. You are granting each person a primitive role for different levels of access, depending on their responsibilities in the project. Which of the following are not included as primitive roles in Google Cloud Platform?
- Answer Choices:
- A. Owner
- B. Publisher
- C. Editor
- D. Viewer
- Correct Answer: B
- Explanation: Google Cloud Platform primitive roles include Owner, Editor, and Viewer. Publisher is not a primitive role.
7. Question: You are deploying a new custom application and want to delegate some administration tasks to DevOps engineers. They do not need all the privileges of a full application administrator, but they do need a subset of those privileges. What kind of role should you use to grant those privileges?
- Answer Choices:
- A. Primitive
- B. Predefined
- C. Advanced
- D. Custom
- Correct Answer: D
- Explanation: Custom roles can be created to grant a specific subset of privileges tailored to the needs of the DevOps engineers.
8. Question: An app for a finance company needs access to a database and a Cloud Storage bucket. There is no predefined role that grants all the needed permissions without granting some permissions that are not needed. You decide to create a custom role. When defining custom roles, you should follow which of the following principles?
- Answer Choices:
- A. Rotation of duties
- B. Least principle
- C. Defense in depth
- D. Least privilege
- Correct Answer: D
- Explanation: The principle of least privilege should be followed to grant only the permissions necessary for the app to function.
9. Question: How many organizations can you create in a resource hierarchy?
- Answer Choices:
- A. 1
- B. 2
- C. 3
- D. Unlimited
- Correct Answer: A
- Explanation: Each GCP account can have only one organization resource.
10. Question: You are contacted by the finance department of your company for advice on how to automate payments for GCP services. What kind of account would you recommend setting up?
- Answer Choices:
- A. Service account
- B. Billing account
- C. Resource account
- D. Credit account
- Correct Answer: B
- Explanation: A billing account is used to manage payments and automate billing for GCP services.
11. Question: You are experimenting with GCP for your company. You do not have permission to incur costs. How can you experiment with GCP without incurring charges?
- Answer Choices:
- A. You can’t; all services incur charges.
- B. You can use a personal credit card to pay for charges.
- C. You can use only free services in GCP.
- D. You can use only serverless products, which are free to use.

- Explanation: GCP offers a range of free services that can be used without incurring charges.
12. Question: Your DevOps team has decided to use Stackdriver monitoring and logging. You have been asked to set up Stackdriver workspaces. When you set up a Stackdriver workspace, what kind of resource is it associated with?
- Answer Choices:
- A. A Compute Engine instance only
- B. A Compute Engine instance or Kubernetes Engine cluster only
- C. A Compute Engine instance, Kubernetes Engine cluster, or App Engine app
- D. A project
- Correct Answer: D
- Explanation: Stackdriver workspaces are associated with a GCP project.
13. Question: A large enterprise is planning to use GCP across a number of subdivisions. Each subdivision is managed independently and has its own budget. Most subdivisions plan to spend tens of thousands of dollars per month. How would you recommend they set up their billing account(s)?
- Answer Choices:
- A. Use a single self-service billing account.
- B. Use multiple self-service billing accounts.
- C. Use a single invoiced billing account.
- D. Use multiple invoiced billing accounts.

- Explanation: Granting iam.serviceAccountUser at the project level ensures the administrator can manage
all service accounts in the project, including any new ones that are created.
15. Question: You work for a retailer with a large number of brick and mortar stores. Every night the stores upload daily sales data. You have been tasked with creating a service that verifies the uploads every night. You decide to use a service account.
