SNCF — Securing Networks with Firepower — Question 101

What must be implemented on Cisco Firepower to allow multiple logical devices on a single physical device to have access to external hosts?

Answer options

• A. Add at least two container instances from the same module.
• B. Set up a cluster control link between all logical devices.
• C. Define VLAN subinterfaces for each logical device.
• D. Add one shared management interface on all logical devices.

Correct answer: C

Explanation

The correct answer, C, is essential because VLAN subinterfaces allow each logical device to communicate independently with external networks. The other options do not facilitate external access as effectively; for instance, A talks about container instances, which do not directly relate to external connectivity, while B and D focus on internal management rather than enabling outbound connections.
