Which statement about Cisco Express Forwarding (CEF) is correct?

Cisco Express Forwarding (CEF) is a high-performance, distributed, Layer 3 IP switching mechanism that maintains two primary tables in the data plane for efficient packet forwarding: the Forwarding Information Base (FIB) and the adjacency table. The FIB is derived from the IP routing table and contains the next-hop IP address for specific prefixes, while the adjacency table stores Layer 2 rewrite information (e.g., MAC addresses) for those next hops. This pre-computed information allows routers to forward packets quickly without needing to consult the routing table for every packet. The other options are incorrect because: CEF offloads packet-switching decisions from the CPU to specialized hardware or pre-computed tables, reducing CPU involvement. CEF does not rely on a fast cache; instead, it uses the FIB and adjacency tables, which are more comprehensive and stable than a cache. CEF's forwarding decisions are made directly by looking up information in the FIB and adjacency tables, not by a process scheduled through the IOS scheduler, which is more relevant for control plane operations.
