C. 警告、エラー、ク リティカル、アラート、緊急事態
D. 通知、警告、エラ ー
E. 警告、エラー、クリティカル、アラート
Correct Answer: C
Explanation:
Cisco routers prioritize log messages into 8 levels (0-7), as shown below: LevelLevel
NameDescription 0 Emergencies System is unusable 1 Alerts Immediate action needed 2 Critical
Critical conditions 3 Errors Error conditions 4 Warnings Warning conditions 5 Notifications
Informational messages 6 Informational Normal but significant conditions 7 Debugging Debugging
messages
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.
