Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 297

What is the best definition of the Heartbeat Interval?

Answer options

• A. the interval during which the firewall will remain active following a link monitor failure
• B. the frequency at which the HA peers exchange ping
• C. the interval in milliseconds between hello packets
• D. the frequency at which the HA peers check link or path availability

Correct answer: B

Explanation

The correct answer is B because the Heartbeat Interval specifically refers to the frequency of ping exchanges between HA peers to monitor their status. Option A describes the firewall's active duration post-failure, which is unrelated, while C focuses on hello packets rather than the ping exchange frequency. Option D discusses link or path checks, which pertains to monitoring rather than the specific heartbeat interval.
