How Many vSphere Trust Authority Clusters Can a Trusted Cluster Reference?

A.

In VMware vSphere 7.x, a Trusted Cluster is a group of ESXi hosts that have been configured to participate in a trust relationship with a vSphere Trust Authority (TA) Cluster. The TA Cluster is responsible for issuing and managing the digital certificates that are used to authenticate communication between the hosts in the Trusted Cluster.

To answer the question, a Trusted Cluster can reference up to 4 vSphere Trust Authority Clusters. This is the correct answer option B.

When a Trusted Cluster is created, it is associated with a single TA Cluster by default. However, you can add up to 3 additional TA Clusters to the Trusted Cluster configuration, for a maximum of 4 TA Clusters per Trusted Cluster.

Having multiple TA Clusters can be useful for several reasons. For example, if one TA Cluster becomes unavailable or compromised, the Trusted Cluster can still obtain valid digital certificates from the other TA Clusters. Additionally, if the Trusted Cluster spans multiple geographic locations or data centers, having multiple TA Clusters in different locations can help minimize the impact of network outages or other issues.

Overall, the ability to reference multiple TA Clusters provides greater flexibility and resilience in the management of digital certificates for vSphere hosts in a Trusted Cluster.
