PSE-SOFTWARE-FIREWALL practice question 5 of 25

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

Full set: 151 questions

Answer options

A: Bundling multiple interfaces in an aggregated interface group and assigning HA2

B: Using the heartbeat backup Correct answer

C: Sending heartbeats across the HA2 interfaces

D: Adding a backup HA1 interface Correct answer

Correct Answer:

B. Using the heartbeat backup; D. Adding a backup HA1 interface

Explanation

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. Palo Alto Networks HA Configuration
