An administrator configures logging on a router with the level set to capture severity 4 and anything more serious. Which condition will NOT be recorded under this setting?
- AAn interface line-protocol change down, logged at severity 3 (error)
- BA power supply fault reported by the chassis at severity 2 (critical)
- CA redundancy supervisor failover raised at severity 1 (alert)
- DA routine configuration change notification raised at severity 5 (notification) Correct
Why A is wrong: Severity 3 is numerically lower than 4 and therefore more severe, so it is included when the threshold is set to warnings; this event is recorded, not excluded.
Why B is wrong: Severity 2 is more severe than the level-4 threshold, so critical messages are always captured; a candidate might wrongly think a lower number means lower priority.
Why C is wrong: Severity 1 sits above the warning threshold in importance, so alerts are logged; confusing the inverted scale could make this look excluded when it is not.
Why D is correct: Setting the level to 4 (warning) records severities 0 through 4 only; severity 5 is less severe than the threshold and is filtered out, so this notification is not recorded.
