Why each option
A vCenter Server HA cluster consists of exactly three node types - Active, Passive, and Witness - each with a distinct role in ensuring high availability.
There is no Master node type in vCenter Server HA; the primary node is called Active, and the term Master does not apply to the vCenter HA architecture.
There is no Replica node type in vCenter Server HA; the standby node is called Passive, not Replica, which is terminology used in other clustering or replication technologies.
The Witness node is a lightweight node that monitors the health of the Active and Passive nodes and acts as a tie-breaker to prevent split-brain scenarios during a network partition.
The Active node is the primary vCenter Server instance that handles all management operations and client requests under normal operating conditions.
The Passive node is a fully synchronized clone of the Active node that automatically takes over management duties within seconds if the Active node fails.
