Which protocol can cause overload on a CPU of a managed device?

A.
Netflow

B.
WCCP

C.
IP SLA

D.
SNMP

Explanation:
Sometimes, messages like this might appear in the router console:
%SNMP-3-CPUHOG: Processing [chars] of [chars]

They mean that the SNMP agent on the device has taken too much time to process a request.
You can determine the cause of high CPU use in a router by using the output of the show process
cpu command.
Note: A managed device is a part of the network that requires some form of monitoring and
management (routers, switches, servers, workstations, printers…).
