Option B:
When a failover occurs, the new primary unit sends gratuitous ARP packets to refresh the MAC forwarding tables of the switches connected to the cluster. However, some high-end switches might not clear their MAC tables correctly after a failover. The set link-failed-signal enable command forces the switches to update their MAC forwarding tables by briefly shutting down all interfaces on the former primary unit." (Enterprise Firewall 7.2 Study Guide | Page 98)
This command helps ensure that the switches update their MAC forwarding tables correctly during a failover.

Option D:
The set link-failed-signal enable command causes the former primary unit to shut down all its interfaces (except the heartbeat and reserved management interfaces) for one second when a failover happens." (Enterprise Firewall 7.2 Study Guide |Page 98)
This brief shutdown helps clear the MAC table entries in the switches, ensuring proper traffic redirection to the new primary unit.
