Which table maps packets in an MPLS LSP that exit the same interface, use the same next hop, and share queuing policies?

The correct answer is FEC (Forwarding Equivalence Class). An FEC is a set of packets that are forwarded in the same manner, over the same path, and with the same forwarding treatment. In MPLS, packets belonging to the same FEC are mapped to the same Label Switched Path (LSP), meaning they exit the same interface, use the same next hop, and share queuing policies. LDP (Label Distribution Protocol) is used to distribute labels between MPLS routers, but it doesn't define the grouping of packets. CEF (Cisco Express Forwarding) is a forwarding mechanism used by Cisco routers, optimizing IP packet forwarding, but it's not specific to MPLS FECs. RIB (Routing Information Base) is the routing table that stores routing information, which is then used to populate the FIB (Forwarding Information Base) for CEF, but it doesn't directly define MPLS forwarding equivalence.
