How does Cisco Express Forwarding (CEF) switching differ from process switching on Cisco devices?

A. Cisco Express Forwarding (CEF) switching saves memory by sorting adjacency tables in dedicate memory on the line cards, and process switching stores all tables in the main memory
B. Cisco Express Forwarding (CEF) switching uses adjacency tables built by the CDP protocol, and process switching uses the routing table
C. Cisco Express Forwarding (CEF) switching uses dedicated hardware processors, and process switching uses the main processor
D. Cisco Express Forwarding (CEF) switching uses proprietary protocol based on IS-IS for MAC address lookup, and process switching uses in MAC address table
