Actual exam question from Fortinet's NSE7_EFW-7.2
Question #: 64
Topic #: 1
[All NSE7_EFW-7.2 Questions]

An administrator is configuring two FortiGate devices in an HA cluster. While configuring the devices, the administrator issues the following commands on both HA cluster members:

config system ha
set link-failed-signal enable

In which two ways do these commands impact the HA cluster? (Choose two.)

  • A. They force the switches to update their MAC forwarding tables, when failover happens.
  • B. They force the former primary to send gratuitous ARP packets when the failover happens to indicate that the virtual MAC address is now using a different device.
  • C. They force both HA devices for remote link monitoring to detect an issue in the forwarding path.
  • D. They force the former primary to shut down all its interfaces for one second when failover happens, excluding the heartbeat and reserved management interfaces.

AD is correct In most networks, that’s enough for the switches to update their MAC forwarding tables with the new information. However, some high-end switches might not clear their MAC tables correctly after a failover. So, they keep sending packets to the former primary even after receiving the gratuitous ARPs. In these cases, you should use the command shown on this slide to force the former primary to shut down all its interfaces for one second when the failover happens, excluding heartbeat and reserved management interfaces. This simulates a link failure that clears the related entries from the MAC table of the switches.

This command forces the former primary to shut its interfaces for 1 second following an HA failover resulting in the switches updating their MAC address tables.
