Explanation

The HA4 link is used in Active/Active HA deployments for session synchronization between the two cluster members. The HA4 Keep-Alive Threshold defines the timeframe within which the local firewall must receive keepalive packets from the peer cluster member over the HA4 link. If keepalives are not received within this threshold, the firewall concludes that the peer is no longer reachable via HA4, which can trigger failover actions. Option A describes the Hello Interval. Option B describes the Preemption Hold Time or Promotion Hold Time. Option D describes the Monitor Fail Hold Up Time or a related timer. The HA4 Keep-Alive Threshold is specifically about session-sync link health monitoring between cluster peers.
