Palo Alto Networks System Engineer – Strata — Question 89

What helps avoid split brain in active/passive HA pair deployment?

Answer options

• A. Use a standard traffic interface as the HA2 backup
• B. Enable preemption on both firewalls in the HA pair
• C. Use the management interface as the HA1 backup link
• D. Use a standard traffic interface as the HA3 link

Correct answer: C

Explanation

Using the management interface as the HA1 backup link is effective in preventing split brain situations, as it ensures a reliable communication path for failover. The other options either do not address the split brain issue directly or may introduce additional complexity that does not guarantee the same level of reliability in failover scenarios.
