2V0-21.23 Question 161
Single answerYou are configuring a new VMware vCenter SSO domain in a multi-site deployment. The organization requires that users across all sites authenticate using a single SSO domain while ensuring high availability. Which configuration step is required to achieve this?
- A
Deploy multiple vCenter Server instances in Enhanced Linked Mode within the same SSO domain.
- B
Create a separate SSO domain for each site and link them using vSphere Replication.
- C
Configure an external Platform Services Controller (PSC) for each vCenter Server instance.
- D
Enable Active Directory integration for each vCenter Server instance in the deployment.
Show answer and explanation
Correct answer: A
Explanation
In a multi-site deployment, using Enhanced Linked Mode within the same SSO domain ensures that all vCenter Server instances share a common authentication framework, enabling users to log in once and access resources across all sites. This approach simplifies management while maintaining high availability and scalability.
- A. Correct.
Deploying multiple vCenter Server instances in Enhanced Linked Mode within the same SSO domain allows administrators to manage multiple vCenter Servers in a single pane of glass while maintaining a unified authentication system across all sites.
- B. Incorrect.
Creating a separate SSO domain for each site would isolate authentication and management, which does not fulfill the requirement for users to authenticate across all sites using a single SSO domain.
- C. Incorrect.
Configuring an external Platform Services Controller (PSC) is no longer recommended in vSphere 7.x and later, as it has been deprecated. Using an embedded PSC within the same SSO domain is sufficient for most deployments.
- D. Incorrect.
Enabling Active Directory integration for each vCenter Server instance allows users to authenticate using AD credentials, but it is not directly related to configuring a unified SSO domain across sites.
