Refer to the exhibit. A LAN interface connected from FortiGate to two FortiSwitch devices is shown. Which two statements about the LAN interface connection shown in the exhibit are correct? (Choose two answers)

  • A. You must enable Spanning Tree Protocol (STP) or Rapid STP (RSTP) on FortiGate and FortiSwitch to avoid layer 2 loopbacks.
  • B. FortiGate is using an SD-WAN-type interface to connect to one FortiSwitch device with MCLAG.
  • C. The connection is using a FortiLink interface.
  • D. The LAN interface must use an 802.3ad type interface.

I don't think this needs to be a fortilink interface

From Study Guide:
You can connect FortiGate to a single FortiSwitch using an aggregate interface. However, using Multichassis Link Aggregation (MCLAG) with multiple FortiSwitch devices enhances layer 2 redundancy, allowing two FortiSwitch devices to act as one unit.
Both scenarios typically use FortiLink with a standard 802.3ad protocol to connect the firewall and switches.

https://docs.fortinet.com/document/fortiswitch/7.6.4/fortilink-guide/173292/configuring-stp-settings
STP is not supported between a FortiGate unit and a FortiSwitch unit in FortiLink mode.

802.3ad (LACP Link Aggregation) without MCLAG won't work as both FortiSwitches are not a cluster yet

MCLAG works with FortiSwitches, not SDWAN
