• A
  80% (49)
• C
  20% (12)

Explanation

Options A, B, and D correctly describe how bandwidth resources are classified in virtual firewall systems. A is correct because outbound traffic (private-to-public) is subject to outbound bandwidth limiting policies. D is correct because inbound traffic (public-to-private) is subject to inbound bandwidth limiting policies - together, A and D establish the directional traffic-policing model. B is correct because the Virtual-if interface used in cross-virtual system forwarding is classified as a public network interface by default, meaning traffic crossing it is treated as external-facing for policy purposes.

Option C is wrong because it inverts the definition: the public network interface is the one connecting the firewall to the external/internet-facing network, not the internal corporate network. The interface connecting to the internal private network is the private network interface.

Memory tip: Think of "public" as "outside world" and "private" as "inside home." Traffic leaving home (private → public) = outbound limit (A); traffic entering home (public → private) = inbound limit (D). The Virtual-if bridge between virtual systems is treated as a door to the outside (public), so B follows naturally.
