Which two statements are correct about a Juniper Packet Forwarding Engine?

The Packet Forwarding Engine is the forwarding-plane component responsible for high-speed packet handling. Juniper documentation states that the PFE performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. This makes option A correct because transit traffic is forwarded by the PFE rather than by the control plane. The Routing Engine manages and programs the PFE by building routing information and copying the forwarding table to the PFE, making option B correct. Option C reverses the relationship and is therefore incorrect. Option D is also incorrect because routing tables are created and maintained by the Routing Engine and routing protocol processes; the resulting forwarding information is then installed into the PFE for packet forwarding.
