Which two design options address split brain when configuring high availability (HA)?

[Reference: The HA documentation for PAN-OS describes the use of heartbeat backups to maintain HA integrity and prevent split-brain conditions., Palo Alto Networks HA Configuration Guide, Adding a Backup HA1 Interface:, Configuring a backup HA1 interface provides redundancy for the primary HA1 link, ensuring continued communication between HA peers even if the primary link fails. This setup is crucial for maintaining synchronization and preventing split-brain scenarios., Reference: The configuration guide for HA in PAN-OS includes steps for setting up a backup HA1 interface to enhance HA reliability., Palo Alto Networks HA Configuration, , ]
