How many vSphere Trust Authority Clusters can a Trusted Cluster reference?

A Trusted Cluster can reference a maximum of one vSphere Trust Authority Cluster. This architecture is designed to maintain a streamlined and secure trust relationship between a Trusted Cluster and the vSphere Trust Authority. By limiting the connection to a single vSphere Trust Authority Cluster, VMware ensures that the integrity and security of the trust relationships are maintained without complicating the management or potentially exposing the environment to multiple points of trust authentication.

This design choice ultimately helps simplify security management, as the policies and rules governing the Trusted Cluster can be consistently applied without the added complexity of managing multiple vSphere Trust Authority Clusters. This approach aligns with best practices for security and design in virtualization environments, focusing on minimizing vulnerabilities while ensuring that trust relationships are clear and manageable.
