SNCF — Securing Networks with Firepower — Question 148

A Cisco FTD has two physical interfaces assigned to a BVI. Each interface is connected to a different VLAN on the same switch. Which firewall mode is the Cisco FTD set up to support?

Answer options

• A. high availability clustering
• B. active/active failover
• C. transparent
• D. routed

Correct answer: C

Explanation

The correct answer is 'transparent' because this mode allows the Cisco FTD to operate without routing, enabling it to bridge traffic between VLANs. The other options, such as high availability clustering and active/active failover, pertain to redundancy and availability rather than the bridging function that the BVI provides.
