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

Using the Heartbeat Backup:

The heartbeat backup is a mechanism that helps to prevent split-brain scenarios in a high availability

(HA) configuration by providing an additional path for heartbeat communication. This ensures that both

firewalls in the HA pair are aware of each other's status.

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.
