An administrator would like to configure vSphere HA to use two isolation addresses. How would this affect the behavior of HA?

HA does not restart the host itself; when isolation is confirmed, HA restarts the virtual machines running on the isolated host, not the host hardware.

vCenter Server IP is used as a default isolation address when none are manually configured, not as a fallback or secondary mechanism when custom isolation addresses fail.

When two isolation addresses are configured, vSphere HA uses an OR logic to determine isolation status - the host is only considered isolated if it cannot reach ANY of the configured isolation addresses. If at least one isolation address remains reachable, the host is deemed to have network connectivity and will not be marked as isolated, preventing unnecessary VM restarts.

If only one isolation address is reachable, the host retains network connectivity confirmation and will NOT be considered isolated - this choice states the opposite of correct HA behavior.
