An engineer reviews a router's logs and discovers the following entry. What is the event's logging severity level? Router# *Jan 01 38:24:04.401: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up
A. Error is correct. The Number in %LINK-3-UPDOWN indicates this is logging level 3:
Number of the desired severity level at which messages should be logged. Messages at or numerically lower than the specified level are logged. Severity levels are as follows:
0 —emergency: System unusable
1 —alert: Immediate action needed
2 —critical: Critical condition—default level
3 —error: Error condition
4 —warning: Warning condition
5 —notification: Normal but significant condition
6 —informational: Informational message only
7 —debugging: Appears during debugging only

Answer is A (Interfaces up/down status is an error)
From https://community.cisco.com/t5/networking-documents/how-to-configure-logging-in-cisco-ios/ta-p/3132434
Router messages
0 Emergencies System shutting down due to missing fan tray
1 Alerts Temperature limit exceeded
2 Critical Memory allocation failures
3 Errors Interface Up/Down messages
4 Warnings Configuration file written to server, via SNMP request
5 Notifications Line protocol Up/Down
6 Information Access-list violation logging
7 Debugging Debug messages
Logging severity messages:
seq no:timestamp: %facility-severity-MNEMONIC:description
severity - Single-digit code from 0 to 7 that is the severity of the message
In this case it is 3 therefore error...
Yes but would a link going UP rather than DOWN really generate an error?
But even if not a typo, go by the severity level # in the syslog for the answer.
