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

Question

Options

• AAdd at least two container instances from the same module.
• BSet up a cluster control link between all logical devices
• CAdd one shared management interface on all logical devices.
• DDefine VLAN subinterfaces for each logical device.

• A
  3% (1)
• C
  5% (2)
• D
  93% (37)

Explanation

On Cisco Firepower chassis (FXOS), when multiple container instances (logical devices) share a single physical interface, VLAN subinterfaces are used to give each logical device its own logical path to the external network. The physical interface is configured as a trunk carrying multiple VLANs, and each logical device is assigned one or more VLAN subinterfaces. This allows all logical devices to reach external hosts through the same physical uplink while remaining logically isolated. Option A is incorrect - adding container instances alone does not provide external access. Option B (cluster control link) is for clustering, not external connectivity. Option C (shared management interface) only handles management traffic, not data-plane access to external hosts.
