Which technology does CEF switching use on Cisco hardware-based routers to forward packets?

  • forwarding engines implemented in specialized ASICs
  • router general-purpose CPU
  • interVLAN routing using subinterfaces
  • route processors using stateful switchover
    Answers Explanation & Hints:

    CEF switching on Cisco hardware-based routers uses forwarding engines implemented in specialized ASICs to forward packets. Cisco software-based routers use the general-purpose CPU for packet switching. InterVLAN routing using subinterfaces is not a CEF technology, and route processors using stateful switchover is a redundancy technology used by routers.
