Q: 19
An organization is implementing Cisco FTD using transparent mode in the network. Which rule in the
default Access Control Policy ensures that this deployment does not create a loop in the network?

B , because in transparent mode the default policy blocks all multicast and broadcast traffic, which is what can cause bridging loops if left unchecked. If the question was only about STP loops, then C would come into play. Anyone else think of a weird edge case here?
Pretty straightforward, it's B. Denying multicast and broadcast by default in transparent mode helps prevent L2 loops since those types of frames could flood and cause looping. Saw a similar question in some exam reports. Anyone disagree?
Its B but does the question specify if they're worried about BPDU traffic or just general loop prevention? If the main concern is blocking spanning-tree BPDUs, then maybe C instead. Depends on what exactly they're asking.
