D is correct as the project is already created

Project Billing Manager cannot create a billing account, there is nothing like Billing Administrator it is Billing Account Administrator. Both Project Billing Manager and Billing Account Administrator cannot create a billing account. A is the only answer that make sense. We have to assume the the billing acount is already created

Hmm doesn't seem like any of these answers are correct. But the Billing Account Admin has the same privileges and additional ones when compared to the Project Billing Manager. YET, B is the only answer that says create a new billing account. This is a tough one, but I would go with answer D if it showed on the test.

All are more or less wrong. We need both Billing Account User and Project Billing Manager. But if I have to choose I choose B (it's the only option that creates an account) https://cloud.google.com/billing/docs/how-to/billing-access it [Billing Account User] has very restricted permissions, so you can grant it broadly. When granted in combination with Project Creator, the two roles allow a user to create new projects linked to the billing account on which the Billing Account User role is granted. Or, when granted in combination with the Project Billing Manager role, the two roles allow a user to link and unlink projects on the billing account on which the Billing Account User role is granted.

D is correct as my opinion because: This role is an owner role for a billing account. Use it to manage payment instruments, configure billing exports, view cost information, link and unlink projects and manage other user roles on the billing account. By default, the person who creates the Cloud Billing account is a Billing Account Administrator for the Cloud Billing account. and When granted in combination with the Billing Account User role, the Project Billing Manager role allows a user to attach the project to the billing account, but does not grant any rights over resources. Project Owners can use this role to allow someone else to manage the billing for the project without granting them resource access.

Answer is B

Answer is B

I'm quite confused since the question is explicitly mentioning "Creating New Billing Account" however neither "Project billing manager" nor "Billing Administrator" has the permission to create a billing account. Only the billing creator can!!

I think its A. C and D refers to Billing Administrator and there is only Billing Account Administrator, so C abd D are out. Only left is A and B. Both Project Billing Manafer cannot create billing accounts, he can only link and unlink billing accounts to projects, NOT create them. Thus, the option left is A, and it makes sense, cause that role can link projects to billing accounts and update the exisiting project with that new billing accoubt.

b seems more legit

Option B is the accurate approach. As a Project Billing Manager, you have the authority to create a new billing account and link it to an existing Google Cloud Platform project. This way, you maintain control over both the project and its associated billing. Option A involves updating the existing project to link it to the existing billing account, which is not the correct sequence for creating a new billing account and linking it to the project.

B is correct answer.Bill Administrator cannot create A billing account

Project Billing Manager (roles/billing.projectManager) Link/unlink the project to/from a billing account. Organization, folder, or project. When granted in combination with the Billing Account User role, the Project Billing Manager role allows a user to attach the project to the billing account, but does not grant any rights over resources. Project Owners can use this role to allow someone else to manage the billing for the project without granting them resource access.

B is the correct answer

D is the correct answer As per GCP docs neither the Billing Administrator nor Project Billing Manager can create billing account. so by assuming that account is already created , we only have to link it Project Billing Manager role has to be combined with the Billing Account User role to be able to link a project to billing account so the correct answer must be D . https://cloud.google.com/billing/docs/how-to/billing-access#relationships-between-resources

Billing Administrator and Project Billing Manager both can link and unlink projects to/from a billing account. Billing Administrator does not have permission to create new billing account. hence it can be linked to existing account only. However, Project Billing Manager needs additional role as "Billing Account User" to attach the project to the billing account. the question says "You need to create a new billing account" but neither Billing Administrator and Project Billing Manager have the permission to create new billing account. Therefore best matching option is that user should have Billing administrator role and use existing account to link to existing projects.

The answer is B. If you read all options carefully, the only option talk about new billing account is B.
