Google Professional Cloud Security Engineer Question 99
Select 3Google Cloud PlatformYour organization uses Google Workspace and a third-party identity provider (IdP) to manage user authentication. You are tasked with setting up access to a Google Cloud application using SAML for single sign-on (SSO). Which of the following steps are required to successfully configure SAML-based authentication for your Google Cloud application?
- A
Configure the identity provider with your service provider details, including the ACS (Assertion Consumer Service) URL and Entity ID.
- B
Enable the OAuth 2.0 API for the Google Cloud project to allow token-based authentication.
- C
Upload the identity provider's metadata file or configure the SAML settings manually in the Google Workspace Admin console.
- D
Ensure the Google Cloud application has an associated OAuth consent screen configured to allow user authentication.
- E
Map user attributes (e.g., email, name) in the identity provider to the appropriate fields in the service provider.
Show answer and explanation
Correct answers: A, C, E
Explanation
To enable SAML-based single sign-on (SSO) for a Google Cloud application, you must configure the identity provider (IdP) and service provider (SP) to communicate with each other. This includes setting up the ACS URL and Entity ID in the IdP, uploading IdP metadata to the Google Workspace Admin console, and mapping user attributes between the IdP and SP. Steps involving OAuth, such as enabling the OAuth 2.0 API or creating an OAuth consent screen, are unrelated to SAML and are not required for SAML-based SSO.
- A. Correct.
Correct: Configuring the identity provider with the service provider details (such as ACS URL and Entity ID) is a mandatory step to set up SAML-based authentication. This allows the IdP to know where to send authentication responses.
- B. Incorrect.
Incorrect: OAuth 2.0 API is unrelated to SAML-based authentication. OAuth is a separate authorization framework, while SAML is specifically used for single sign-on (SSO).
- C. Correct.
Correct: Uploading the IdP metadata file or configuring SAML settings manually in the Google Workspace Admin console ensures that Google Workspace can properly communicate with the IdP for SAML authentication.
- D. Incorrect.
Incorrect: The OAuth consent screen is only relevant for OAuth flows, not for SAML-based SSO. SAML does not require an OAuth consent screen.
- E. Correct.
Correct: Mapping user attributes between the identity provider and the service provider ensures that the correct user information is passed during SAML authentication, which is essential for successful login.
