SNCF — Securing Networks with Firepower — Question 157

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?

Answer options

• A. Multicast and broadcast packets are denied by default
• B. STP BPDU packets are allowed by default.
• C. ARP inspection is enabled by default.
• D. ARP packets are allowed by default.

Correct answer: B

Explanation

The correct answer is B because allowing STP BPDU packets ensures that the Spanning Tree Protocol can function properly, preventing network loops. Options A, C, and D do not directly address the prevention of loops, as they focus on packet types that do not manage the topology of the network.
