Which three requirements are true for the vCenter Server HA network? (Choose three.)
The correct answer is B. IP addresses for all nodes must be static. C. HA network IP addresses for all nodes can be on different subnets. E. A default gateway must be configured. vCenter Server HA requires static IP addresses for all nodes, allows HA network IPs on different subnets, and requires a default gateway to be configured for inter-node communication.

Why each option
vCenter Server HA requires static IP addresses for all nodes, allows HA network IPs on different subnets, and requires a default gateway to be configured for inter-node communication.
The documented latency requirement for vCenter HA is less than 10 milliseconds for the management network, but this specific statement is not listed among the three core HA network requirements.
Static IP addresses are mandatory for all vCenter HA nodes (active, passive, and witness) to ensure reliable heartbeat and replication traffic without DHCP lease interruptions.
The vCenter HA network is explicitly designed to allow nodes on different subnets, providing flexibility in network topology as long as routed connectivity exists between nodes.
vCenter HA network IP addresses are not required to be on the same network as the management network; they can and typically should be on a dedicated, separate network.
A default gateway must be configured so that vCenter HA nodes can reach each other when they reside on different subnets, enabling proper failover communication.
