Which switching method is used when entries are present in the output of the command show ip cache?

A. fast switching

B. process switching

C. Cisco Express Forwarding switching

D. cut-through packet switching








 

Suggested Answer: A

Fast switching allows higher throughput by switching a packet using a cache created by the initial packet sent to a particular destination. Destination addresses are stored in the high-speed cache to expedite forwarding. Routers offer better packet-transfer performance when fast switching is enabled. Fast switching is enabled by default on all interfaces that support fast switching.
To display the routing table cache used to fast switch IP traffic, use the "show ip cache" EXEC command.
