Why each option
In a FortiGate High Availability (HA) cluster, there is only one master unit responsible for synchronizing configuration changes to all slave units.
A FortiGate HA virtual cluster strictly operates with a single master unit at any given time, which is responsible for processing traffic and managing the cluster's state.
The master unit in a FortiGate HA cluster maintains the authoritative configuration and is responsible for automatically synchronizing all configuration changes to the slave units, ensuring cluster consistency.
Reserved management HA interfaces can be configured on all units within an HA cluster, including slave units, to allow for independent access and management.
Heartbeat interfaces are crucial for all units in an HA cluster, including the master, as they are used to monitor the health, synchronization, and failover status among cluster members.
