Refer to the following:
Logging Console 7 -
Which option is one of the effects entering this command on a Cisco IOS router, with no additional logging configuration?

A. Debug messages can be seen on the console by enabling "terminal monitor."

B. Debug messages are logged only on active console connections.

C. A user that is connected via SSH sees level 7 messages

D. The router can experience high CPU utilization








 

Suggested Answer: B

Console logging: By default, the router sends all log messages to its console port. Hence only the users that are physically connected to the router console port can view these messages.
The router does not check if a user is logged into the console port or a device is attached to it; if console logging is enabled, messages are always sent to the console port that can cause CPU load.
To stop the console logging, use the "no logging console" global configuration command. You might want to limit the amount of messages sent to the console with the "logging console level" configuration command (for example, logging console Informational).
