Q: 15
Refer to the exhibit, which shows a LAN interface connected from FortiGate to two FortiSwitch
devices.
What two conclusions can you draw from the corresponding LAN interface? (Choose two.)

B and C for sure. You need 802.3ad LAG for connecting to MCLAG peers, and that interface is always used for FortiLink when managing downstream switches/VLANs from FortiGate. Pretty standard setup unless something's changed in recent firmware, right?
I don’t think A fits, it’s B and C. FortiGate needs 802.3ad for MCLAG and FortiLink manages the VLANs, not SD-WAN.
B/C work here. The picture basically shows an 802.3ad LAG, and FortiLink is always what's used for FortiGate switch management. Not seeing anything that points to SD-WAN or STP config being needed in this context.
B and C tbh. That's what pops up in both the official docs and most practice sets covering FortiLink and switch stacking stuff, no SD-WAN in this one. Let me know if you saw anything different in other exam reports.
From what I've seen in the official guide and a couple of practice tests, it's B and C here. 802.3ad is a must for MCLAG, and FortiLink does the VLAN management. Pretty sure-let me know if there's a different config.
B and C match what's in the official guide and practice tests for FortiLink with MCLAG. The LAG has to be 802.3ad, and FortiLink manages VLANs. Not 100% sure unless they ask about loop prevention, though. Disagree?
Kinda feel like A is valid here. Since you have multiple switches, enabling STP or RSTP seems important to prevent loops at L2. I've seen network loops in similar setups if STP isn't enabled. Not completely sure though, maybe I'm missing something about how FortiLink handles redundancy? Agree?
Option D looks tempting since SD-WAN gets mixed up with multi-link stuff, but here it's just a regular LAG with FortiLink, not SD-WAN. I think D is a trap, but I could see why someone might pick it.
B/C make sense here. The interface needs to be 802.3ad (B) for aggregation and FortiLink is used to centrally manage VLANs (C). Not seeing any SD-WAN or STP requirement in this context. Anyone disagree?
Pretty sure it's B and C, saw a similar question on a practice exam. Matches the 802.3ad and FortiLink setup.
Be respectful. No spam.
