Which two statements about logging are true? (Choose two.)

A.    Log messages are sent to the console port by default.

E.    System restart messages are logged at the Critical level.
F.    Reload requests are logged at the Notification level.

Answer: AC
By default, switches send the output from system messages and debug privileged EXEC commands to a logging process. The logging process controls the distribution of logging messages to various destinations, such as the logging buffer, terminal lines, or a UNIX syslog server, depending on your configuration. The process also sends messages to the console.
The software generates four other categories of messages:
• Error messages about software or hardware malfunctions, displayed at levels warnings through emergencies. These types of messages mean that the functionality of the switch is affected. For information on how to recover from these malfunctions, see the system message guide for this
• Output from the debug commands, displayed at the debugging level. Debug commands are typically used only by the Technical Assistance Center.
• Interface up or down transitions and system restart messages, displayed at the notifications level. This message is only for information; switch functionality is not affected.
• Reload requests and low-process stack messages, displayed at the informational level. This message is only for information; switch functionality is not affected.
