Which two methods will help avoid Split Brain when running HA in Active/Active mode? (Choose two.)
Which two methods will help avoid Split Brain when running HA in Active/Active mode? (Choose two.)
To avoid Split Brain in an Active/Active HA setup, it is crucial to ensure consistent communication between the devices to avoid both acting as active units simultaneously. Configuring a Backup HA1 Interface ensures that a backup communication link is available if the primary HA1 interface fails. This maintains the synchronization between the devices. Configuring a Heartbeat Backup establishes an additional mechanism to monitor the heartbeats between them, ensuring that each device is aware of the other's status and preventing Split Brain scenarios by avoiding simultaneous active states.

AB are correct
The split-brain conditions can be prevented by configuring the "HA1" backup-link and enabling heartbeat backup.
