Refer to this output. What is the logging severity level? R1#Feb 14 37:15:12:429: %LINEPROTO-5-UPDOWN Line protocol on interface GigabitEthernet0/1. Change state to up

The correct answer is A. Notification. Explanation Option A is correct because the number 5 in %LINEPROTO-5-UPDOWN directly indicates the syslog severity level, and level 5 corresponds to Notification (also called "Notice"). The Cisco syslog severity scale runs from 0 to 7, where each number maps to a specific level:

Explanation

Option A is correct because the number 5 in %LINEPROTO-**5**-UPDOWN directly indicates the syslog severity level, and level 5 corresponds to Notification (also called "Notice"). The Cisco syslog severity scale runs from 0 to 7, where each number maps to a specific level: 0=Emergency, 1=Alert, 2=Critical, 3=Error, 4=Warning, 5=Notification, 6=Informational, and 7=Debugging. Options B (Alert) and D (Emergency) are wrong because Alert = level 1 and Emergency = level 0 - both are much higher in severity. Option C (Critical) is wrong because Critical = level 2, not level 5.

Memory Tip: Use the mnemonic "Every Awesome Cisco Engineer Will Need Daily Inspiration" → Emergency, Alert, Critical, Error, Warning, Notice, Debug, Informational - then just match the number in the syslog message to its position (starting at 0) to identify the severity level instantly.
