Answer: C
Cisco Discovery Protocol is a proprietary protocol to allow
you to
access configuration information on other routers and
switches with a
single command. It uses SNAP at the Data-Link Layer. By
default CDP
sends out a broadcast every 60 seconds and it holds this
information for
180 seconds. CDP is enabled by default.
