Overall, C seems the best choice. Loop prevention is key!
DE

I feel like B is important too. Denying multicast can help.
MA

True, but without STP, loops can still happen. C is safer.

But what about A? ARP inspection could also play a role.

I agree, C makes sense. It helps maintain the network topology.

I think it's C. STP BPDU packets are crucial for preventing loops.

B) Multicast and broadcast packets are denied by default, though.

Totally agree, C is the right choice!

Wait, are we sure about that? Sounds off.

B) Multicast and broadcast packets are denied by default. Ah, the sweet smell of a loop-free network.

I'm just hoping the default policy doesn't include "Deny all the things!" - that would be a real loop-de-loop.

C) STP BPDU packets are allowed by default. Gotta keep those bridges spanning!
EL

D) ARP packets are allowed by default. This is important for transparent mode to work properly.

B) Multicast and broadcast packets are denied by default. This prevents loops in the network.

I feel like allowing ARP packets is crucial, but I don't know if that directly addresses the loop issue in transparent mode.
BO

I practiced a similar question where multicast packets were involved, and I think they were denied by default, which might help here.
DE
Dexter

I remember something about ARP inspection being important, but I can't recall if it directly prevents loops.

I think the key here is B. Denying multicast and broadcast packets by default would be a way to prevent loops in a transparent deployment. The other options don't seem as directly relevant.

I'm a bit confused on this one. I know Cisco FTD can operate in transparent mode, but I'm not sure how the default policy handles things like STP and ARP. Gonna have to review my notes.
CO
Colette

I thought ARP inspection was the key here?
CH

C) STP BPDU packets are allowed by default.
CL
Clement

I think it might be related to STP BPDU packets, but I'm not entirely sure if that's the right choice.
GE

Okay, I've got a strategy. I'll focus on the default policy settings and how they impact layer 2 protocols and broadcast/multicast traffic. That should point me to the right answer.
PE
Percy

Hmm, this seems tricky. I'm not super familiar with Cisco FTD and transparent mode, so I'll need to think through the network implications carefully.
IZ
Izetta

I think the key here is to understand how Cisco FTD in transparent mode affects the network topology. The default policy needs to handle things like ARP and STP to avoid loops.
TR

Multicast and broadcast denial also plays a role in stability.
NI
Nikita

But what about ARP inspection? Isn't that important too?
SU

True, allowing those packets is essential.
JU

I believe STP BPDU packets are crucial for preventing loops.
LA

Yes, but it mainly helps with ARP spoofing, not loops.
