C.
Session polling
Answers

Session polling
D.
Link monitoring
Answers
D.
Link monitoring
Suggested answer: A, D

Explanation:

Heartbeat polling and link monitoring are two mechanisms that can trigger an HA failover event. Heartbeat polling is a method of verifying the health of the peer firewall by sending periodic heartbeat messages. If the heartbeat messages are not received within a specified interval, the firewall assumes that the peer is down and initiates a failover. Link monitoring is a method of verifying the connectivity of the interfaces on the firewall by sending link state packets. If the link state packets are not received on a specified number of interfaces, the firewall assumes that the network is down and initiates a failover. Ping monitoring and session polling are not HA mechanisms, but they are used for path monitoring and session synchronization respectively.
