Explanation:
Cisco routers prioritize log messages into 8 levels (0-7), as shown below:
When you enable logging for a specific level, all logs of that severity and greater (numerically less)
will be logged. In this case, when you enable console logging of warning messages (level 4), it will
log levels 0-4, making the correct answer warnings, errors, critical, alerts, and emergencies.
Incorrect Answers:
: When you enable logging using a value such as warning, all message of that severity and greater
(numerically less) will also be logged.
: Only the warnings and other more severe messages will be logged, so in this case levels 0-4 will be
logged.
: The correct answer is warnings, errors, critical, alerts, and emergencies.
