Palo Alto Networks Certified Strata Field Engineer (PCSFE) — Question 1
Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)
Answer options
- A. Heartbeat polling
- B. Ping monitoring
- C. Session polling
- D. Link monitoring
Correct answer: A, D
Explanation
Heartbeat polling is a critical mechanism for monitoring the health of nodes in an HA setup, allowing for quick failover when a failure is detected. Link monitoring also plays a vital role by ensuring that network connections are active; if a link fails, it can trigger a failover. Ping monitoring and session polling are not typically used for HA failover detection.
