Suggested Answer: B,C Vote an answer
The diagram shows a FortiGate connected to two FortiSwitches, which suggests the use of FortiLink, Fortinet's protocol for managing switches directly from a FortiGate. Since multiple connections are being used, the LAN interface must be set to 802.3ad (LAG) mode to aggregate the links for redundancy and load balancing.
This setup allows FortiGate to handle VLAN assignments dynamically, as seen with VLAN 10 (192.168.15.1
/24). FortiLink ensures seamless integration between FortiGate and FortiSwitches, making STP unnecessary because Fortinet's MCLAG prevents loops at Layer 2. SD-WAN, on the other hand, is used for WAN interfaces and does not apply to switch connectivity in this scenario.
