Correct answer: When a destination PE device receives a labeled packet, it pops the label and uses it to forward the packet to the correct CE device..
Why this is the answer
The correct answer describes the penultimate step in MPLS L3 VPN forwarding. The egress PE receives a packet with a VPN label (inner label) and possibly a transport label (outer label). It pops the VPN label, revealing the IP packet. The egress PE then uses the IP packet's destination address to perform a standard IP lookup in the correct VRF (Virtual Routing and Forwarding) table associated with the CE device. Finally, it forwards the packet to the appropriate CE device without any MPLS labels. The first incorrect option describes an EIGRP redistribution scenario, not MPLS L3 VPN forwarding. The third incorrect option describes the ingress PE's action, not the egress PE's. The fourth incorrect option describes how VPN routes are handled when learned from a CE, not the forwarding action of labeled packets.
