Which are four attributes of the Active vCenter HA node? (Choose four.)
The correct answer is A. It runs the active vCenter Server Appliance instance. C. It uses a public IP address for the management interface. E. It uses the vCenter HA network for replication of data. F. It uses the vCenter HA network to communicate with the Witness node.. The Active vCenter HA node runs the live vCenter Server instance, holds the management IP, and uses the dedicated HA network for both data replication to the Passive node and heartbeat communication with the Witness node.

Why each option
The Active vCenter HA node runs the live vCenter Server instance, holds the management IP, and uses the dedicated HA network for both data replication to the Passive node and heartbeat communication with the Witness node.
The Active node hosts the running vCenter Server Appliance instance that services all management traffic, making it the primary operational node in the vCenter HA cluster.
Providing quorum to prevent split-brain scenarios is the role of the Witness node, not the Active node - the Witness casts the deciding vote when the Active and Passive nodes cannot communicate with each other.
The Active node is assigned a public (management network) IP address that clients and administrators use to connect to vCenter Server, distinguishing it from the Passive and Witness nodes which have only HA network addresses.
vPostgres data is replicated between the Active node and the Passive node only - the Witness node stores no database data and participates only in quorum/heartbeat functions.
Data replication - including vPostgres database changes and configuration state - travels over the dedicated vCenter HA network between the Active and Passive nodes to avoid saturating the management network.
The Active node uses the vCenter HA network to send heartbeat signals and state information to the Witness node, which uses those signals to determine whether a failover should be triggered.
