A network administrator is configuring a Syslog server to collect log messages from multiple network devices. Which severity level indicates that a system is unusable and requires immediate attention, typically resulting in a system crash?
- AAlert
- BEmergency
- CCritical
- DError
Show answer & explanationAnswer & explanation
Correct answer: B. Emergency
The 'Emergency' (level 0) severity level in Syslog indicates that a system is unusable, often due to a system crash, and requires immediate attention. It is the highest severity level.
Why the other options are wrong
- A. Alert (level 1) means immediate action is needed, but the system might still be partially functional.
- C. Critical (level 2) indicates a critical condition, but not necessarily a complete system crash.
- D. Error (level 3) indicates error conditions that might still allow some functionality.
Syslog Severity: Emergency
The highest Syslog severity level (level 0), indicating that the system is unusable, often due to a crash, and requires immediate attention.
- Severity level 0.
- Most critical log message type.
- Often associated with system failures or crashes.
Memory trick: An 'Emergency' is the ultimate system-stopping crisis.
